Hello Ed and all, Theoritical is maybe not appropriate, yes small impacts do occur, as do large ones. The remedy to the situation is theoritical. Mainly when...

Hi, Is anyone in Europe able to observe 9V04E48 during these few hours? It looks like we are having a near miss. Thank you, Andrea Boattini The Catalina Sky...

Hello all, The Rosetta spacecraft will be flying by us on 13 November. I thought this should be mentioned, since it's already been mistaken once for a natural...
Hello all, A while back, I was discussing a lost close-approacher with somebody and mentioned that it would be really nice if there was somebody in Hawaii,...
Hello all, A small note: I'm getting many solutions for 9V04008 that are as much as a degree east of the current NEOCP ephemeris. The uncertainty map shows a...
