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

Shown above at 02:30 UTC/03:30 BST on 6th May, the Aquarid meteor shower will be active from the end of April until the end of May (click to enlarge) – Credit: Sky-Watching/Stellarium

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!

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

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 :)

April showers of the Lyrid kind

April 17, 2013

by yaska77

Beginning now until the 25th of this month we see the April Lyrid meteor shower (peaking on April 22nd before dawn). The meteors in this shower tend to be bright and leave persistent trails as they enter the Earth’s atmosphere.

In recent years the shower has seen anything from 10 to 20 meteors per hour.

We caught this Perseid meteor flashing across the night sky in August 2012, so we’re hoping to have clear skies for the Lyrids! (click to enlarge) – Credit: Sky-Watching/A.Welbourn

Although that might sound like a fairly mediocre “shower”, it has been known for the Lyrids to surge to over 100 per hour! This is what makes this shower so difficult to predict. How many will we see?

Will it be a downpour of shooting stars or a washout this year!?

Although the meteors will seem to originate from Lyra, they can appear all over the sky. Shown above at 01:00 UTC (02:00 BST) on 22nd April just at the start of the peak (click to enlarge) – Credit: Sky-Watching/Stellarium

Lyrid meteors originate from a radiant point in the constellation of Lyra which is where this shower gets its name. The best time to look for Lyrid meteors is late in the evening after 21:00 UTC (22:00 BST) however, the waxing gibbous Moon will still be in the sky until the early hours so its light may wash out the fainter meteors.

Another Perseid from August 2012, this one has more definition to the shape at the end of the streak and is seen heading away from the Andromeda galaxy (click to enlarge) – Credit: Sky-Watching/A.Welbourn

Don’t let this deter you though, the unpredictable nature of the Lyrid shower is what makes it worth watching so we hope you have clear skies!

Now we’ve expressed an interest we’re expecting it to be cloudy, but amateur astronomers are nothing if not optimistic :)

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)

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!
