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.

25 years of the Hubble Space Telescope

Roger O’Brien

The Hubble Space Telescope (HST) is a space telescope that was launched into low Earth orbit in 1990, and remains in operation. With a 2.4-meter (7.9 ft) mirror, Hubble's four main instruments observe in the near ultraviolet, visible, and near infrared spectra. The telescope is named after the astronomer Edwin Hubble.


Hubble's orbit outside the distortion of Earth's atmosphere allows it to take extremely high-resolution images with negligible background light. Hubble has recorded some of the most detailed visible-light images ever, allowing a deep view into space and time. Many Hubble observations have led to breakthroughs in astrophysics, such as accurately determining the rate of expansion of the universe.


Although not the first space telescope, Hubble is one of the largest and most versatile, and is well known as both a vital research tool and a public relations boon for astronomy. The HST was built by the United States space agency NASA, with contributions from the European Space Agency, and is operated by the Space Telescope Science Institute. The HST is one of NASA's Great Observatories, along with the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope.[6]


Space telescopes were proposed as early as 1923. Hubble was funded in the 1970s, with a proposed launch in 1983, but the project was beset by technical delays, budget problems, and the Challenger disaster. When finally launched in 1990, Hubble's main mirror was found to have been ground incorrectly, compromising the telescope's capabilities. The optics were corrected to their intended quality by a servicing mission in 1993.
