The International Space Station 10:39 p.m. on Sunday 24th April 2011

I had watched the earlier 9:04 p.m. crossing of the ISS and this lasted nearly 5-minutes at almost the same elevation as the 10:39 p.m. crossing.  So why was the 9:04 p.m. crossing 5-minutes long and the 10:39 p.m. crossing only 3-minutes long?  The accompanying image tells the story.  At 10:39 p.m. the Sun has set further, so the ISS is illuminated for less of its course across the sky.  As you can see in the image – it barely makes Ursa Major before its lights out – fascinating!

Progress 41P and the International Space Station

Passing almost directly overhead (83 degees) on 22nd April 2011 were the automated Russian cargo vehicle Progress 41P and the International Space Station.  Progress 41P first appeared in the West at 9:48 p.m. followed just one minute later by the International Space Station (ISS).  Both disappeared from view in the ENE at an elevation of 25 degrees.  In this image both tracks are overlaid as they were both in the same orbit.  It was a fantastic sight with just a layer of thin high cloud preventing perfection (and preventing me from imaging).

Parker/Carboni do a wide-field of the Whale & Hockey Stick (galaxies) region of Coma Berenices

Recently processed by Noel Carboni this data was acquired just a few days ago at the New Forest Observatory.  This image shows the Whale & Hockey Stick galaxies in Coma Berenices, and to the lower/far left there are a pair of tiny interacting galaxies called “The Mice”.  What would be an unbalanced frame gains balance between the bunch of bright stars at the bottom and the small galaxies at the top.  Unfortunately it is not always possible to play this trick 🙂
