This image of globular cluster M13 was taken on 20th March, 2012 by Simon Edwins from his home in Bedfordshire, UK. Simon used a Canon 350D SLR at prime focus on an 8" F/4.5 Orion Optics CT8reflector. The image is a stack of 10x 3 minute exposures and stacking was carried out using Nebulosity, with post processing in Photoshop.

Peter Edwards took this image of the new supernova in Messier 95 on 27th March, 2012 using a Celestron C11 SCT operating at f/6.3 and an SBIG ST2000XCM camera. Eight sub frames of 5 minutes duration were used to create the final image.

As the sun continues to throw some of it's material in our direction, Alan Tough has submitted some of his best images of the auroral display on 15th March. The image was taken using a Canon EOS 60D and Sigma EX 24-60mm lens

A brace of bright supernovae

Two ‘bright’ supernovae in nearby galaxies are well within the range of most amateur astronomers telescopes.

Supernova Candidate PSN J10435372+1140177 in M95 – now designated 2012aw

Supernova 2012aw imaged by Nick James on March 18th

This supernova was discovered on 2012 March 16.8493 by J. Skvarc & Alessandro Dimai of the Italian Supernovae Search Project.

M95 is at R.A. = 10h43m53s.72, Decl. = +11°40′17″.7 (= NGC 3351) and the SN is located 60″ west and 115″ south of the center of M95. M95 is well placed for observation, transiting at around 23:00 UT, with the galaxy culminating at about 50° altitude.  M95 is part of the Leo I group of galaxies, about 38 million light years distant.

A discovery image can be found here:

Nick James observation of this object (above) puts it at about magnitude 13 and adds that unfortunately Mars is very close and has caused significant interference with the image.  However, Mars will continue to move further away as time progresses.

And here is an image by Martin Mobberley, the following night:

 

Supernova 2012aw imaged by Martin Mobberley on March 19th

 

SN 2012au in NGC 4790 in Virgo

Discovered by the Catalina Real-Time Transient Survey and Stan Howerton (USA) at mag 18.2C on 2012 March 14.450 but it has rapidly brightened and is currently at magnitude 13.25V.   This SN is of Type Ib, and apparently found in the early stages of its evolution so it may well brighten further.

However, it is vary close to the core of the host galaxy, but is the brightest supernova so far this year. Recent images etc can be found here: http://www.flickr.com/photos/watchingthesky/6846911246

NGC 4790 is at R.A. = 12h54m52s.18, Decl. = -10°14′50″.2 and the SN is located 3″.5 east and 2″.0 north of the center of NGC 4790. NGC 4790 is not very far from Saturn, but currently culminates at about 27° altitude at around 01:00 UT.

BAA member John Bell, who is Vice Chair of the Milton Keynes Astronomical Society, took this interesting image of Jupiter and Venus as they passed each other in the evening sky during March. This image was taken on 11th March and John used a Canon 5D SLR fitted with a 200mm lens at f/8. It is a 5sec exposure at ISO 100 andshows the Jovian moonsIo Ganymede and Callisto.

The picture is a composite of a full moon shot taken withJohn's 8 Newtonian at f6 (f4x teleconverter) 1/200sec , and a crescent at 1/20sec. The full moon shot was then darkened and given a blue tint in photoshop cs5 to simulate the earthlit moon. The crescent was slightly resized to match the scale of the full moon and pasted on top. The intention was to capturethe whole scene to look like an idealised earthlit moon. The final effect is quite dramatic.

Splendid aurora observed on 15th March

Yesterday evening, following much agitation of the Earth’s magnetic field, an aurora (the northern lights) was viewed by many from the north of Scotland. Poor weather in other areas may have prevented views further south.

BAA member Denis Buczynski captured a few images of the display from Portmahomack, which will give a flavour for what was seen.  These were taken between 20:58 and 23:48 with a Canon 400D and a 28mm lens at f2.8 at ISO 800.  Exposures were all about 30 secs.
