one-hour flood of false spots

I get the odd false spot on my database now and then, but for about 40 minutes earlier today (4 July 2010) I got a flood of them, about 30 all told, with about 14 fake callsigns and grids. Never saw that happen before. All on 30 meters. Don't see any signs of unusual solar activity in that period. No signs of anything amiss with antenna, rig, interface or computer. I operate receive-only. My map looks pretty impressive for the last 24 hours. Too bad most of it is fake. The flood of junk began at 1146 UTC and lasted until 1220 UTC.

Anybody know of an explanation?
