CAS September 11th meeting: Change of Speaker |
|
Thursday, 26 August 2010 |
|
Unfortunately Dr Peter Hargrave, who was to be the speaker at the next CAS meeting, can't make it. He has very kindly found someone to speak in his place. Professor Matt Griffin has agreed to give the talk on September 11th. Matt is the principal investigator for the SPIRE instrument on the Herschel Space Observatory, and will give a talk on Herschel and it's science results.

Noctilucent Clouds viewed from Gloucestershire |
|
Tuesday, 15 June 2010 |
 CAS Member James Weightman viewed and recorded a display of Noctilucent Clouds last night (or more accurately 2.00 a.m. this morning), from his location near Cirencester. James made this video by using a time-lapse switch with a Canon DSLR with 85mm lens to take a series of 72 images
at 10 second intervals.

 At the Society meeting on Saturday, I mentioned the possibility of this comet reaching naked eye visibility in late May, early June. I have collated an overview chart and ephemeris from the BAA in this pdf ,
Note that this will probably be a challening object to see, and probably even harder to image. It will be low in the north-east, and it will be around mid-summer, with bright skies. However, I hope some members will be up for the challenge!
Also I read today that Comet 2009 K5 is also moderately bright, not naked eye, but possibly within range of binoculars.
A good place for comet information is the BAA Comet Section website .

Messier Observing Programme |
|
Monday, 07 July 2008 |
|
In order to encourage Society members (new and old, beginners and experienced) to spend more quality time at the eyepiece, we are launching a new Observing Programme based on the 110 Messier objects.
he aim of the Programme is to provide a structured approach to finding and observing these most spectacular of deep-sky objects. In addition, the Society will confer Awards (Silver, Gold and Platinum) on members who achieve certain observing goals and submit their completed observation logs to the Observing Director. A “roll of honour”, listing those who have received Awards, will also be maintained and published on the Society web site.
Star-hopping hints and tips for finding well-placed objects will be included in issues of Mercury throughout the year, and it is envisaged that helping observers hunt for their as-yet-unseen Messier objects will form a part of Society Observing Evenings during the winter months.
