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.

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!?

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.

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 – January 2013

December 31, 2012

by yaska77

We’d like to take this opportunity to wish all our visitors a very happy and prosperous New Year! 2013 has much potential for stargazing and we’ve vowed to bring you more photos and articles than ever before.

As usual we’ve highlighted below some great heavenly happenings throughout January to keep your eyes skyward and don’t forget UK astro fans, Stargazing Live! returns to our screens on the 8th January for another series.

It’s all very exciting! :)

Wednesday 2nd January – The Earth is at Perihelion today, the point in it’s orbit where it passes closest to the Sun

Thursday 3rd January – The best time to try catch some of this year’s Quadrantid meteor shower is probably after nightfall this evening. The peak is actually around the middle of the day, but with the Moon rising later tonight (around 23:15 UTC) some of the fainter meteors will be lost in the glare as midnight approaches

While the Quadrantids can produce hundreds of meteors an hour, this year the ZHR in the early evening is expected to be lower at around 10-20 meteors per hour.

If you’ve got clear skies however any meteor shower is worth craning your neck for so wrap up warm, get outside and see how many you can spot!

Saturday 5th January – Today is a last quarter Moon

Tuesday 8th January – The BBC’s ever popular Stargazing Live! returns to our screens this evening (BBC2/BBC HD 20:00 UTC) as hosts Professor Brian Cox and comedian Dara O Briain kick off the new series looking at Mars exploration

Wednesday 9th January – This evening Stargazing Live! will look into how it is possible to chart the history of the Universe by looking millions of light years out into the depths of space (BBC2/BBC HD 20:00 UTC)

Thursday 10th January – The Moon is at Perigee today at a distance of 360,045 km (223,722 miles), the closest point in its orbit to the Earth

In the final episode of this series of Stargazing Live! Professor Brian Cox and Dara O Briain discuss meteors, comets and asteroids, and examine what the study of them reveals about the origins of life (BBC2/BBC HD 20:00 UTC)

Friday 11th January – This evening it’s a New Moon which rises and sets just before the Sun. This makes it a good time to observe deep sky objects like NGC 2244, an open cluster of stars in the heart of the Rosette Nebula in Monoceros, found to the right of Orion

I took the image above last February after watching an episode of Stargazing Live! It was a late night but the images I got were worth the lack of sleep I believe (click here to see for yourself!)

Saturday 12th January – A 21 hour old slither of crescent Moon may just be visible low down to the southwest immediately after sunset this evening. If you have clear skies and a zoom lens on your camera you may be able to get a shot of this faint but illusive occurrence

Friday 18th January – Today is a first quarter Moon, and the planet Mercury is in Superior Conjunction. This means it is on the opposite side of the Sun to the Earth so will be unobservable until the end of the month

Monday 21st January – Jupiter appears high in the sky this evening, midway between the Hyades and Pleiades clusters (see below). Joining the bright winter object is the waxing gibbous Moon which may dim the stars around it

Tuesday 22nd January - Today the Moon is at Apogee at a distance of 405,310 km (251,848 miles), the farthest point in its orbit to the Earth

Sunday 27th January – The Full Moon this morning is also sometimes called the Wolf Moon, Ice Moon or Old Moon

Thursday 31st Jaunary – Mercury makes a brief appearance low down in the southwest just after sunset. Those with a flat horizon and clear skies may find this a challenging photo target (but then Mercury usually is!)

Planets visible this month:

Mercury
Venus
Mars
Jupiter
Saturn
Uranus
Neptune

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! :)

Perseid Meteor Shower – 12th August 2012

August 12, 2012

by yaksa77

After the dress rehearsal for this morning’s Perseid meteor shower peak provided so many sightings on Friday I had hight hopes. Never one to conform to expectations though, the run up to the peak was decidely slow starting and a bit lacklustre!

Undeterred by this, or the stubborn refusal of evening cloud to move on, I still set out just gone midnight to the Wye Downs in mid-Kent. Despite only capturing a few flashes with the camera eventually the show sparked into life, and in just over an hour I saw 33 meteors!

Taken using a Canon EOS 550D at 18mm focal length, f/3.5, 20 second exposure at ISO-1600 – 12th August 2012 (click to enlarge) – Credit: Sky-Watching/A.Welbourn

This is probably the best of the photos I got while out in the countryside, I love the way the meteor flashed into view right in the middle of a gap in the clouds.

The Pleiades cluster is also nice and bright, and you can see Jupiter is just rising at the base of the fence post directly below the meteor!

This one shows a nice long clear Perseid tail with more definition to the shape at the end of the streak, heading away from Andromeda – 12th August 2012 (click to enlarge) – Credit: Sky-Watching/A.Welbourn

After a few hours I packed up and headed home to find the skies had cleared over my house. Not wanting to miss the opportunity I set up again and caught a few more (the best of which are above and below). In the image above the Perseid can be seen streaking away from an oval smudge that is the Andromeda galaxy.

I’m so pleased that after my disappointment with the faint efforts I got last year, over the last two nights I’ve caught some nice clear examples of one of nature’s most beautiful free displays!

Another clear Perseid streak, this time with a faint green tint to the tail! 12th August 2012 (click to enlarge) – Credit: Sky-Watching/A.Welbourn

I’m not sure what the weather forecast is for this evening but the shower should still be fairly strong, and I feel on a bit of a roll at the moment so may just set the camera up again tonight.

Well, I wouldn’t want to miss anything would I!? :)

Warming up to the Perseid show

August 11, 2012

by yaska77

As you probably know, the annual Perseid meteor shower peaks this evening (check our monthly guide for some more info) but because it was clear last night I set up my camera in the garden, more out of hope than expectation.

My history of trying to photograph meteors has been sketchy at best (see last years attempt here) but last night I was left grinning like a cheshire cat!

18mm focal length, f/3.5, 15 sec exposure at ISO1600 – This is easily the best meteor photo i’ve taken (click to enlarge) – Credit: Sky-Watching/A.Welbourn

I approach photography with a “try lots of settings and see” kind of attitude, and I’ve found what works initially may not look as good an hour later (light pollution quite often gives me orange skies if I don’t pay attention). Normally I wouldn’t have the ISO as high as 1600 for long exposure star shots, but anything lower was producing too much of an orange tint.

Still, I’m very pleased with the shot above, lots of stars, a bright Perseid meteor flash and it’s not too faded.  The other shots I caught weren’t as clear, but one did stand out as the meteor flashed by a cool little cluster that you can’t usually see with the naked eye (unless you’re lucky enough to have dark skies!)

Another Perseid meteor flashes past Brocchi’s Cluster (the upside down coat hanger!) in this cropped image from early on 11th August 2012 (click to enlarge) – Credit: Sky-Watching/A.Welbourn

Brocchi’s Cluster can be found within the imagined lines of the “Summer Triangle“, about a third of the way from Altair in a straight line to Vega.  It’s also known as the “Coathanger” for obvious reasons!

And so on to this evening.  My camera’s batteries are charging, the tripod is ready and the weather forecast is (currently) still favourable, so I’m planning a little trip out of town tonight to slightly darker skies. It’s building up to be a good show, and if I get any more images I’ll post them here!

And if you capture any photos of your own, please feel free to tweet them to us as we’d love to see them!

Enjoy the show :)

Astronomy Events – May 2012

April 30, 2012

by yaska77

Despite a relatively good start to April, the proverbial showers soon set in and the second half of the month has been a washout under one rainstorm after another!

It can’t rain all the time though (can it!?), and with May now upon us there’s a whole new list of astronomical events coming up to cater for everyone!

Tuesday 1st May - Mercury rises before the Sun just after 04:00 UTC (05:00 BST) in the eastern sky

Thursday 3rd May – Venus is still visible after sunset over the west northwest horizon, and will gradually move closer to the setting Sun over the course of the month

Sunday 6th May – The Eta Aquarid meteor shower peaks this morning with a ZHR of around 30 per hour (see below). The radiant is in the constellation Aquarius that comes up over the eastern horizon around 01:30 UTC (02:30 BST) on 6th May, but meteors could appear anywhere across the sky

Tonight’s Full Moon is also at Perigee (356,955 km)

Monday 7th May – Saturn appears close to the blue giant Spica this evening, shown below to the south at 22:30 UTC (23:30 BST). At this time the Moon is also rising to the east close to the red giant Antares, which means “rival of Mars”

Saturn will be close to the blue giant Spica directly south at 22:30 UTC/23:30 BST (click to enlarge) – Credit: Sky-Watching/Stellarium

Saturday 12th May – Last Quarter Moon

Sunday 13th May – Jupiter is in conjunction with the Sun, and won’t be visible all month

If you’ve got a telescope M13 is well worth a look in the early hours of 17th May (click to enlarge) – Credit: Sky-Watching/Stellarium

Thursday 17th May – The Great Globular Cluster M13 in the constellation Hercules is at its highest at 01:00 UTC (02:00 BST) this morning (see above). We’ve always wanted to image this, and having had a go at lesser cluster M37 last year (below) we’re hoping it stays crystal clear this evening!

We imaged the M37 cluster in January this year, but M13 is much more impressive! (click to enlarge) – Credit: Sky-Watching/A.Welbourn

Saturday 19th May - Moon is at Apogee (406,450 km)

Sunday 20th May – New Moon which rises and sets with the Sun, so tonight is a good time for looking at deep sky objects

Tuesday 22nd May – Venus appears just above and to the right of the waxing crescent Moon this evening, which will set about an hour and a half after the Sun

Imaging the crecent Moon and Venus can get good results, in January they were opposite to how they’ll appear on 22nd May, when they’ll also be closer! (click to enlarge) – Credit: Sky-Watching/A.Welbourn

Wednesday 23rd May - This is the time of year to start looking for noctilucent clouds, which sometimes appear low down in the northwest (after sunset) and northeast (just before sunrise)

These clouds are in the upper atmosphere and are usually too faint to see, becoming visible only when illuminated by sunlight from below the horizon while the lower layers of the atmosphere are in the Earth’s shadow

Sunday 27th May – Mercury is at Superior Conjunction

Monday 28th May – First Quarter Moon

Planets visible this month:

Mercury
Venus
Mars
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!
