The Gaia mission from ESA continues to provide a wealth of data on stellar positions and motions.
If you're not familiar, it's a satellite that continuously scans the sky as it rotates, plotting the position of stars with unprecedented accuracy. As the satellite moves with the Earth around the sun, this gives it the scope to measure the parallax of a billion stars in our galaxy, and measure the proper motion of a lot of them too. The satellite is fitted with a spectroscope so that it can measure the radial velocity of stars as well, allowing ESA to develop a catalogue of stars with velocity measurements in 3 dimensions.
ESA has recently issued a subset of measurements, showing the movement of 2 million stars projected forward for the next 5 million years.

Saturday 16th November at Jodrell Bank Discovery Centre:
Comet ISON has sparked a lot of public attention and we are waiting eagerly to see if it is as prominent in the sky as we hope by the end of the year. Professor Jamie Gilmour, our colleague and expert in geology and planetary science, will join us at Jodrell Bank on Saturday 16th November to talk about Comets, Asteroids and Meteorites â€“ the things that are left behind when planets form.
We are delighted that we will also be joined by a host of amateur astronomers for the evening, who will bring along their telescopes so that, weather permitting, we can have a joint viewing of the night sky.
Please let us know when you purchase your ticket, if you plan to bring your own telescope with you to the event.
Adult £9.00 (suitable for 16 +)
Please note tickets are non refundable
Times 7.00pm to 9.00pm
Pre-event dining : Dinner can be pre booked with sittings at 5.45pm, 6.00pm, 6.15pm and 6.30pm. Space is limited to 50 people. The cafe will be open for light refreshments to non diners. ( menu on www.jodrellbank.net)
Note: if any members would like to be part of the stargazing section and work the event, we are permit up to a maximum of 4 members plus a guest who are able to bring telescopes with them. if anyone is interested please do let me know as soon as possible as I will be..:-)

We're going to be at Delamere Forest for the transit, arriving around 11:30am on Monday May 9th. The transit begins at 12:12 and ends at 19:41. We may not be there for the whole event so get in touch via the Facebook Page, or Dave or Malc if you want to come much later on.
If anyone from the club (or interested members of the public) wants to join in, please arrive whenever you can at the Old Pale car park. We'll have some solar scopes but please feel free to bring your own.
