What is an Aurora?

What causes It?

What do we know about the Aurora?

Can we see any from the UK?

What happens at our meetings?


Doors open at 7:30 for the meeting due to start at 8:00 but several club members and friends gather before this to have a drink and chat in the bar.


Following welcome announcements we have a guest speaker who speaks on the subject of the evening for about 45 - 60 minutes.  This is followed by questions relating to the talk.


Announcements about forthcoming events follow.


You can then choose from the following activities:

  1. If the weather is clear telescopes and binoculars brought by members are set up outside for some observation.  Members doing so will be pleased to share their scopes with others.
  2. If you need help with some equipment then now is your chance to bring it in.  Others in our club will be more than willing to help you .  Don’t be shy, we get just as excited about a telescope bought at the charity shop for £20 as we do one costing many times more.
  3. Just socialise with others - about anything!


We look forward to seeing you.

Star formation in our Galaxy

Carla Natario

Observations at Infra-red and sub-millimetre wavelengths carried out with the JCMT and Herschel telescopes have revealed that the ISM in our Milky Way is highly organized in cold and dense filamentary structures. The most massive of these structures  are believed to be the initial conditions of massive star and star cluster formation.


A large effort has been done in the past to determine the global physical properties of these clouds and of their dense (and cold) clumps/cores and filaments. However, it still remains poorly understood the role of filaments in star formation; how this clouds form and fragment into dense clumps, and how these clumps subsequently fragment and evolve.


In this talk, I will present my ongoing work on the characterization of the internal physical structure, fragmentation and gas dynamics in these cold regions.

8:00 - 10:00pm


Doors open at 7:30 although the bar is open earlier for a drink
