Showcase 2015

DSC_4541_1260At the April AGM meeting Peter Cadogan showed the entries for this years astro-photo competition for the Dan Turton trophy.

As many members were not able to attend that night, and not able to view or vote, those who did not vote on the night can view the pictures in the Showcase 2015 gallery, and vote by emailing your 1st, 2nd and 3rd choice favourite pictures to Peter Cadogan (coordinator@cotswoldas.org.uk). Please use the number on the image slide. Voting is open until Sunday 26th April.

The Showcase gallery images are generated from Peter’s powerpoint and are a somewhat downscaled from the originals – so apologies to the imagers that their images may not be the best quality possible.

Mutual Phenomena of Jupiter

Jupiter on 2014 December 24 by Ian Sibley
Jupiter on 2014 December 24 by Ian Sibley

During 2015, the Jupiter system will be edge-on to the Earth and Sun, which allows observers to see fascinating phenomena of the Galilean moons. First, this alignment allows the moons and the shadows to transit across the Equatorial Zone so that observers have the greatest chance of seeing one or more of them on the disk. Second, it allows the moons to eclipse and occult one another in so-called ‘mutual phenomena’. These events can be followed even with modest telescopes, especially mutual eclipses where one can see the rapid dimming of the eclipsed moon even if it cannot be resolved. Larger telescopes do allow the moons to be resolved, and should allow some impressive images and even videos to be obtained.
John Rogers, BAA

Tony Ireland has prepared a listing of mutual events to look out for.
