Astronomy Events – May 2013

April 30, 2013

by yaska77

Hot on the heels of an unexpected break in the weather (allowing us to see April’s partial eclipse of the Moon) we’re eager to get stuck in to another new month of astronomical events!

Now spring has finally arrived in the UK we’re hoping to be able to get some new images to show you, and if you get any snaps yourself please feel free to tweet them to us.  Is there anything in particular you’re looking forward to?

Thursday 2nd May – The Moon is at Last Quarter phase today

Monday 6th May – The Eta Aquarid meteor shower peaks early this morning (01:30 UTC/02:30 BST) with an expected ZHR of 10 meteors per hour as viewed from the UK (observers from more southern latitudes could see up to 55 per hour).  Appearing to originate from the constellation Aquarius (hence the name), Aquarids are known for bright tails left by fast moving meteors

Thursday 9th – Friday 10th May – An annular solar eclipse occurs today when the Moon’s apparent diameter is smaller than that of the Sun (blocking most of its light) which causes it to look like a ring (or annulus)

This type of eclipse appears as a partial eclipse over a region thousands of kilometres wide, and will be visible from northern Australia and the southern Pacific Ocean, with the maximum of just over 6 minutes visible from the Pacific Ocean east of French Polynesia

The eclipse begins at 21:25:10 UTC

Friday 10th May – Today sees a New Moon so now is a good time for observing deep sky objects usually affected by moonlight

Saturday 11th May – Bright planets Venus and Jupiter flank the Moon just after sunset.  Shown below at 19:45 UTC/ 20:45 BST, if your NW horizon is flat enough this could be a great target for some photos!

Jupiter, the Moon and Venus all pay Taurus a visit soon after sunset this evening, look WNW and see if you can spot them! (click to enlarge) – Credit: Sky-Watching/Stellarium

The planet Mercury is also in Superior conjunction today, so is unobservable until later in the month

Monday 13th May – The Moon is at Apogee today at a distance of 405,825 km (252,168 miles), the farthest point in its orbit from the Earth

Saturday 18th May – This morning the Moon is at First Quarter phase

Saturday 25th May – Today’s Full Moon will experience another penumbral eclipse (where it skims the edge of the Earth’s shadow), this time however it will be virtually imperceptible unlike the partial eclipse witnessed on 25th April

Penumbral Eclipse 25042013 21.22 BST Sky-Watching.co.uk

In April the Full Moon also experienced penumbral eclipse, shown above at 20:22 UTC (21:22 BST) with the Earth’s shadow visible across the northern edge (click to enlarge) – Credit: Sky-Watching/A.Welbourn

May’s Full Moon is also sometimes known as the Milk Moon, Dragon Moon or Hare Moon

Sunday 26th May – Soon after twilight this evening the planets Jupiter, Mercury and Venus should be visible forming an equilateral triangle to the WNW (West North-West)

Jupiter, Mercury and Venus 26052013 20.15 UTC Sky-Watching.co.uk

Forming an equilateral triangle in the twilight sky, Jupiter, Mercury and Venus appear close to each other just after sunset on 26th May, as shown at 20:15 UTC/21:15 BST (click to enlarge) – Credit: Sky-Watching/Stellarium

These planets will be near neighbours from 23rd to 31st of this month, but appear closest together this evening

And today the Moon is at Perigee at a distance of 358,375 km (222,684 miles), the closest point of its orbit to the Earth

Friday 31st May – Tonight sees the Moon at Last Quarter phase; and twilight planets Jupiter, Mercury and Venus appear aligned soon after sunset

Planets visible this month:

Jupiter
Saturn
Venus
Mercury

Remember, it can take your eyes up to 20 minutes to become properly dark adapted, and anything up to an hour for a telescope to reach ambient temperature outside (to ensure the best image), so give yourself plenty of time to get set up!

To make it easier to find this list of astronomical happenings you can also locate it in the “Monthly Guide” section in the menu bar to the right. Handy! :)

Astronomy is contagious!

April 29, 2013

by yaska77

The great thing about astronomy is that anyone with a sky over their heads can get involved. You don’t need a truckload of expensive gear, just an interest and a modicum of patience will get you a long way!

Soon after I got my camera and started posting images on this blog, Mick Judd (a talented photographer who I happen to work with) also began skywatching, and he has captured some great shots with limited “astro-specific” equipment.

After we recently discussed the upcoming penumbral eclipse on 25th April (see our images here) Mick went home and over the course of a few evenings has produced the following short video, which we hope you enjoy.

We think it’s great, and just the sort of thing we hope will help others catch the astronomy bug! But how did he do it?  I’ll let him explain that himself!

“To capture the images I used two different eyepieces on a D=60mm F=700mm telescope; an H20 to fit the whole of the moon in the frame and an HF6 for the close-ups of the lunar surface and for Saturn. To attach the camera (a Sony Ericsson Xperia Arc S mobile phone) I drilled a hole in the middle of a plastic lid from a can of hair mousse, and glued it around the lens hole on the phone’s protective case.

Slotting the plastic lid over the eyepiece housing on the telescope and pushing it into place, it’s then a bit of hit and miss with lining up what I can see in the finder scope with what I can see on the phone’s display. The Xperia Arc S has a lot of camera settings so it’s just a matter of adjusting EV levels and using a bit of digital zoom to fill the frame to avoid seeing the round edge of the eyepiece.

To try and make sure that I capture something that is sharp I slightly tweak the scope’s focus every now and then between shots. The Sunspots were viewed through an additionally fitted Solar filter.  All the footage in the video was captured between 15th and 27th April 2013.”

Top work Judd bloke, and an ingenious set up!

You can see more of Mick’s photos on his Flickr page here

Now everyone get outdoors and enjoy the night sky! :)

Penumbral eclipse, full moon, no clouds!?

April 25, 2013

by yaska77

It’s been a very slow couple of months of late. The British weather is infamous the world over, and not only have we just experienced the first real warmth of spring, but an abundance of evening clouds have kept many a garden astro indoors.

The signs were good this evening however, there was a penumbral eclipse on the April Full Moon (as noted in our April Astro Guide), and not a cloud in the sky! What madness was this!?

Penumbral Eclipse 25042013 21.07 BST Sky-Watching.co.uk

Taken with a Canon Eos 550D and a 250mm lens mounted to a fixed tripod, the penumbral eclipse is visible over the top left edge of the full Moon (click to enlarge) – Credit: Sky-Watching/A.Welbourn

Some time ago the spotter scope on my telescope was knocked out of alignment, so combined with the clouds it’s been a shamefully long time since I used it.

Looking on this evening as a chance to at least re-align the spotter scope (even if the Moon would not rise high enough to see any of the partial eclipse), I set up and found my fence was just low enough for the scope to catch it before the shadow passed!

Now mounted to my Sky-Watcher 200P Telescope, the partial eclipse is still a visible shadow over the northern edge of the Full Moon (click to enlarge) – Credit: Sky-Watching/A.Welbourn

So finally we’ve had an astronomical event that the clouds missed. But not by much I can tell you, an hour after these photos were taken the Moon was enveloped behind a blanket of cloud.

So we do get a break once in a while after all :)

Astronomy Events – April 2013

March 31, 2013

by yaska77

Unfortunately for us, since we told you about the visit of comet PANSTARRS our own skies have seen nothing but clouds! It’s been great seeing all the photos on Twitter, but we’re gutted we’ve not had chance to image it ourselves.

Still, to be a stargazer you have to keep your chin up, so we’ve listed some interesting happenings for April to whet your interest so get out there and keep your eyes on the skies!

Wednesday 3rd April – Today is a last quarter Moon

Monday 8th April – The thin waning crescent Moon will be close to Mercury just before dawn this morning, however the planet will be lost in the brightening sky

Wednesday 10th April – The New Moon this morning rises and sets with the Sun, so it is a good time to observe deep sky objects with the glare from the Moon absent

Saturn can be a great sight through a small telescope or good binoculars, we’re hoping to image it again soon as our only successful previous attempt was a while ago!

Still one of the most amazing sights to see with your own eyes, Saturn and its rings look spectacular through a scope, look South East around 22:30 UTC/23:30 BST (click to enlarge) – Credit: Sky-Watching/A.Welbourn

Sunday 14th April – The waxing crescent Moon will appear quite close to the gas giant Jupiter this evening, you’ll be able to find both between the “horns” of constellation Taurus the Bull (see below)

Moon and Jupiter in Taurus (08042013) 20.00UTC Sky-Watching.co.uk

If you look due West at 20:00 UTC (21:00 BST) on 14th April you’ll see the Moon and Jupiter between the horns of the constellation Taurus (click to enlarge) – Credit: Sky-Watching/Stellarium

Monday 15th April – Today the Moon is at Apogee at a distance of 404,865 km (251,571 miles), the farthest point in its orbit to the Earth

Wednesday 17th April – The planet Mars is in conjunction with the Sun, so is unobservable for the month

Early morning at the moment comet C/2011 L4 (PANSTARRS) is located just to the bottom right of the constellation Cassiopeia (the W to the North). We’re still hopeful of catching a glimpse of this so far elusive celestial object!

Comet PANSTARRS 17042013 0230UTC Sky-Watching.co.uk

Now its brightness is diminishing comet PANSTARRS may prove difficult to spot, but it’s still there! Shown 17th April at 02:30 UTC/03:30 BST (click to enlarge) – Credit: Sky-Watching/Stellarium

Now circumpolar from the UK since the beginning of the month (meaning it doesn’t set), if it follows predictions PANSTARRS may still be naked eye visible if your skies are dark enough

Thursday 18th April – Tonight’s Moon is seen in the First Quarter phase

Sunday 21st April – For information about the Lyrid meteor shower which peaks over the next few evenings, click here

Thursday 25th April – The Full Moon tonight is also sometimes known as the Awakening Moon, Seed Moon or Wildcat Moon, which can be seen close by Saturn all evening

At around 20:00 UTC (21:00 BST) the Moon will be mid-way through a very slight penumbral eclipse, seen as a slight dimming of the Moon’s northern edge caused as it skims the bottom of the Earth’s shadow

Moon and Saturn (25042013) 23.00UTC Sky-Watching.co.uk

A Full Moon can wash out most of the stars in the sky around it, but the brightness of Saturn should still make it visible, and look out for the very partial eclipse around 20:00 UTC (click to enlarge) – Credit: Sky-Watching/Stellarium

Saturday 27th April - Today the Moon is at Perigee at a distance of 362,265 km (225,101 miles), the closest point of its orbit to the Earth

Sunday 28th April – The planet Saturn is at opposition in Libra, meaning that it’s in an opposite position to the Sun in the sky, so is observable from dusk until dawn! This is also the time of year it appears at its brightest

Tuesday 30th April – Venus returns to our evenings skies (albiet briefly) to the west just after sunset, but may be tricky to spot in the twilight

Planets visible this month:

Jupiter
Saturn
Venus

Remember, it can take your eyes up to 20 minutes to become properly dark adapted, and anything up to an hour for a telescope to reach ambient temperature outside (to ensure the best image), so give yourself plenty of time to get set up!

To make it easier to find this list of astronomical happenings you can also locate it in the “Monthly Guide” section in the menu bar to the right. Handy! :)

Astronomy Events – March 2013

February 28, 2013

by yaska77

Well here we are at March already!  Spring is approaching, the days are getting longer and we’re hoping the weather also improves! This month we have the potential of a comet being visible to the naked eye, so read through below for details.

There should be something for everyone to enjoy so keep your eyes on the skies! :)

Monday 4th March – Today is a last quarter Moon and Mercury is in Inferior Conjunction so is not currently visible until towards the end of the month

Tuesday 5th March – The Moon is at Perigee today at a distance of 369,955 km (229,879 miles), the closest point in its orbit to the Earth

Monday 11th March – This evening it’s a New Moon which rises and sets just before the Sun, making it a good time to observe deep sky objects without interference from the Moon’s glare

One such object that looks great through binoculars or a small telescope is M44, the Beehive Cluster (also known as Praesepe)

Look high to the South around 21:00 UTC and you should be able to spot it! (click to enlarge) – Credit: Sky-Watching/Stellarium

We imaged the Beehive Cluster when Mars was passing in front of it in October 2011, and it looked great! If you’re going to try image this object yourself, why not tweet your results to us on Twitter!

The Beehive Cluster is one of the nearest open clusters to our Solar System, approximately 577 light years away (click to enlarge) – Credit: Sky-Watching/A.Welbourn

Wednesday 13th March – Discovered in June 2011, Comet C/2011 L4 (PANSTARRS) reaches Perihelion (its closest approach to the Sun) on 10th March. However, as it is close to our star on this date our best chance of spotting it is from 12th March onwards as it moves away into twilight skies

On 13th March it will appear below the crescent Moon soon after sunset

Friday 15th March – Appearing slightly higher in the sky than on the 13th, the position of Comet C/2011 L4 (PANSTARRS) is shown below. Should it have developed a tail it will point towards the Moon, and if predictions prove true should be visible to the naked eye!

Comet PANSTARRS 15032013 1900UTC Sky-Watching.co.uk

Shown above at 19:00 UTC close to the Western horizon on 15th March, comet PANSTARRS will appear higher each day, but will also diminish in brightness (click to enlarge) – Credit: Sky-Watching/Stellarium

Sunday 17th March – Tonight’s Moon is seen in the First Quarter phase

Tuesday 19th March – Today the Moon is at Apogee at a distance of 404,260 km (251196 miles), the farthest point in its orbit to the Earth

Wednesday 20th March – Today is the Spring Equinox in the Northern Hemisphere

Comet C/2011 L4 (PANSTARRS) should be visible in slightly darker skies after 19:30 UTC, and we are praying for good weather (and to find a flat Western horizon with less light pollution) so we can try and image it! Exciting!

Comet PANSTARRS 20032013 1930UTC Sky-Watching.co.uk

If you look from the middle of the W shaped constellation Cassiopeia and through the Andromeda galaxy you should find the comet just above the horizon, as shown above at 19:30 UTC (click to enlarge) – Credit: Sky-Watching/Stellarium

By the end of the month (and into April) it will appear just below the Andromeda galaxy

Wednesday 27th March – The Full Moon this evening is also sometimes called the Fish Moon, Sleepy Moon or Chaste Moon

Thursday 28th March – The planet Venus is in Superior Conjunction, and Uranus is in conjunction with the Sun

Sunday 31st March – British Summer Time (BST) begins, with the clocks going forward one hour at 01:00 UTC (becoming 02:00 BST).  The Moon is also at Perigee for the second time this month today at a distance of 367,495 km (228,351 miles), and Mercury is at its greatest Western Elongation meaning it may be visible in the Eastern sky before sunrise

Planets visible this month:

Mercury
Jupiter
Saturn

Remember, it can take your eyes up to 20 minutes to become properly dark adapted, and anything up to an hour for a telescope to reach ambient temperature outside (to ensure the best image), so give yourself plenty of time to get set up!
