Next week is Moonwatch week here in the UK (28th of March to 5th of April). This is frankly our way of making up time on the 100 hours of astronomy, because of our rubbish weather. At my home institution, Cardiff University we are holding public events each evening when it is clear, inviting anyone to come and look through our new half-metre telescope.
Elsewhere in the UK many other museums, community centres and schools are also holding Moonwatch events. A pal of mine, Dr. Nutter (no joke), is holding his own tiny Moonwatch on his street in Magor. What a good idea! He wondered if there was a specific Moonwatch poster he could download to advertise the event. We could not find one and so Twitter came into use. Soon enough we had two posters available to us.
One pointed out by @cosmosboy covers any IYA2009 event. The other was created specially by @Space_Jockey and Ewan has created a special minisite about Moonwatch, where you can download the poster (shown above).
