What happens at our meetings?

Doors open at 7:00 for the pre meeting show of astro photographs taken by group members followed by main meeting arrival from 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.  No need to book - just turn up.

Four intrepid members of HAGAS recently drove across Spain to visit an excellent astronomy hosting facility known as Entre Encinas y Estrellas (e-EyE) near Seville. Anthony Challoner, Martin Weston, Denis O'Shea and Stephen Heliczer spent a few nights under crystal-clear skies at this quite unique observing facility as well as sampling the wonderful local food, drink and picturesque scenery in this completely unspoilt part of southern Spain. Speak to Steve or anyone above for further information.  One of the benefits of joining Hertford Astronomy Group is the opportunity for extra-curricular activities such as this!

The Royal Institution Christmas Lectures have been a staple of the festive period for nearly two hundred years. Colin’s book - “13 Journeys Through Space and Time” - looks back at 13 devoted to our understanding of the universe, delving into the historical archives to chart our changing understanding of the cosmos.

With lecturers including James Jeans, Carl Sagan & Monica Grady, you’ll hear behind the scenes secrets and stories of the treasures that Colin found hidden in the archives. We’ll also see just how much our understanding of the universe has evolved over the last century and a bit.

Colin will have copies of his book with him. Cover price £12.99

In 2014 he was the runner-up in the European Astronomy Journalism Prize.

The asteroid (15347) Colinstuart is named after him.

Something to look out for:

Geminid Meteor Shower  - Observable  in December, when the Earth passes through the dust trail left by the asteroid 3200 Phaethon (1983 TB), a Class B-type dark carbonaceous rock comet. At a mean diameter of about 5km (3 miles) and travelling at 20km/s (45,000 mph), it will pass-by the Earth at a distance of 0.068 AU (10.3 million km – 6.4 million miles).

The anticipated number of shooting stars could be 100 – 200 / hr at peak on the 13th - 14th.
