If this had been observed at 20:58 on Saturday, March 25, I would wonder if it could have been related to the launch of the IMAGE satellite at 20:34:43 from Vandenberg AFB into a 93.9-degree inclination orbit. According to Space Today, the Main Engine Cut-Off (MECO) was at 20:39, and first cut-off of second stage (SECO) was at 20:45, when it was at an altitude of 185 km (100 nautical miles). At 20:55 IMAGE was entering a "telemetry gap" of 25 minutes (very high northern latitudes?), and by 21:30 they reported that the third stage had burned out. Alternatively, maybe some other IMAGE event occurred on Sunday, March 26 that could have produced such a cloud occurred 24 hours and some minutes after launch?
