Here's a picture-quiz for you: who can identify this object and explain why it's unique:

I took the image last night (5th November), between 8-9pm.
The field of view is about half a degree across, aligned with North at the top and East to the left.

The answer will be in next month's newsletter.

Nope, Vesta is currently in the constellation of Cancer, so I'd need to wait until after midnight to catch it.

It would have been easier if it was in colour! I can remember drawing this in 1963 and watching the movement!

Is it Comet Johnston.
Using (Heavens Above) and setting it for the time and date you stated.

Well, C/2015 V2 Johnson is very low down in the North at the moment (behind my shed!).
I did manage to catch it last month: http://www.boltonastro.co.uk/forums/viewtopic.php?f=1&t=904

However this time I was pointing SE, and this object is not a comet.
But it is among the objects listed on Heavens-Above. Keep trying!

I've checked with Dave and he was thinking of Uranus or Neptune.
But it was neither of these - their movement in just one hour would not have been so noticeable.

Well then it must be Ceres.
Dwarf planet Ceres is the largest object in the asteroid belt between Mars and Jupiter and the only dwarf planet located in the inner solar system. (Google)
If I'm right you've started something which is a detective search.

Yes Peter, well done.
I had read that Ceres was first counted as a new planet when it was discovered (in 1801), but then became known as an asteroid some years later.
But I hadn't realised until this weekend that it was recently re-classified as a Dwarf Planet, and it is unique in that it is the only one in the inner Solar System - the others (including Pluto) are all in the Kuiper Belt.
