Wednesday 2nd October 2019

Mike said that this Saturday was an Open Night and we should be there for 18.00 or earlier.

He said the venue had changed since our last visit. The scope field is where we did the water rocket launching on our Space Day. He outlined the details and said we must talk to the staff about the leaving procedure to avoid parking charges.

Andrew said that next week would be an Observing Evening or if cloudy Atmospheric Optics by Mike.

He also mentioned that he needs more volunteers for talks.

Jim said we should not forget his equipment which is available to all members.

Ted sad he was still collecting subs.

Mike said a friend has a Vixen 4 inch refractor for sale – tube only. He thought £80 to £100 would secure it. He reminded of his own endeavours with his own Vixen (tube only) - hand held - some time ago and gained nice shots of the ISS.

Peter said our club Star Party at was set for 28th Oct to 4th Nov.

Mike said the business this evening was: Members' Roundup

He started us off with a shot of the last quarter of the Moon – he pointed out two lunar domes that this particular Sun angle showed nicely. They are evidence of volcanic activity.

He mentioned the recent event at Kelling Heath which was blessed with an extraordinary range of weather including some clear skies allowing him to bag some great deep sky objects.

Jim had a lovely image of Abell 84 (PLN 112-10.1) a Planetary Nebula in Cassiopeia.

Also Comet C/2018 N2 (ASASSN) this was discovered a year ago and will reach perihelion next month but will not go much inside the Solar System and will not be brighter than magnitude 11. Plus Comet 260P/McNaught. The distance of it is currently 84,624,996 kilometers, equivalent to 0.565683 Astronomical Units. Light takes 4 minutes and 42.2786 seconds to travel to us.

Jim included finder charts for each of the objects.

Andrew had an image taken with his phone of a purple sky that he had noted it whilst driving and got the pic at his destination n Chelmsford. It was apparently caused by volcanic activity in the southern hemisphere. He also had a shot of a Sun Dog - these are like rainbows that are caused by light refracting through ice crystals and can appear 22.50 degrees either side of the Sun.

Ron had shots from Kelling Heath including a video from inside Andy’s caravan showing torrential rain; however he also had several delightful shots of the starry sky.

Chris had a deep image of the Western Veil Nebula that he had got in three different ways. He said they had needed 50 hours of imaging time.

Peter made a recent visit to Dunsink Observatory in Ireland. It is part of the Dublin Institute for Advanced Studies (DIAS) and integral to the Irish Astronomy Trail, has a long history in the service of science. Research is carried out at Dunsink as part of the programme of research of the Astronomy & Astrophysics Section of the School of Cosmic Physics.

He said he had completed the trip from Southend airport in a single day - attending a meeting there and all for little more than twice the rail fare to London!

He also mentioned his meteor detection camera system that automatically captures anything that moves in field of view - unfortunately this includes wildlife. However he showed us some splendid videos and a composite of meteors over 4.5 hours.

Excellent.
