Only Clear glass filter (Astronomik) for CCD protection was used. Video evaluation accomplished with VirtualDub 1.10.0, Tangra v1.3.1.434 Event data details according to the predictions published on the web site of Felipe Braga-Ribas. http://www.lesia.obspm.fr/perso/braga-ribas/campaigns/2012-02-03_2003AZ84.html Predicted event time was about 19:49:30 UTC for my observing position. Predicted maximum duration was about 25.4 seconds with a 5.2mag drop. Position was about 1400km from last predicted central line in N direction between path edge and 1-sigma limit with a probability of 8%.
