The day began with Roy Williams talking generally about VOEvent and the basic things necessary for the standard which, at least according to Roy, are; curation, when/where, how, what and the hypothesis.

We then had Scott Barthelmy from NASA/GSFC talking about the GRB Co-ordinates Network (GCN) the "grandfather" of all the event notification systems who talked about the GCN and
Next up was Derek Fox talking about the astronomer's telegram which I must admit to not having heard of before. Interestingly, they offer distribution via several RSS feeds...
After a quick break for coffee George Djorgovski talked about the Palomar-Quest Survey and showed some of the actual plates illustrating the different types of transients, and the types of false alarms, that have been picked up during their survey work. Interesting stuff considering our plans for WFCAM.
The final talk before lunch was given by Tim Axelrod who discussed LSST.
Update: Back from lunch, and ready for some more talks...
