This week we at the NSO have passed a rather special milestone - our 150,000th request for an observation. The observation of Jupiter was taken by the Liverpool Telescope early on the morning of Tuesday 8th May and as you can see from the image here, it just caught the moon Io as it was about to pass between us and the planet.

Another exciting thing about this particular observation is that it shows the success of our new class of "NSO User" which opens the NSO up to the world - the observation was requested by a student not in the UK but Thailand.

Don't forget that if you have an interesting observation that you want to share, let us know on the Forums
