(meteorobs) Swift Sees 5th Magn. GRB!

[stange34 at sbcglobal.net]

The Sentinel system would have detected it being -5Mag (IF) there had been 
some motion to it. Sentinel does not normally detect a stationary light 
burst.

My second backup system(HandyAvi) ,would have detected it because it does 
not rely on motion solely....failed because I had forgot to start it after 
setting it up that night. My fault.

That system normally captures light bursts etc., and records many hundreds 
of megabytes each night(mostly from airplanes) which I delete at each time 
of the new nights setup.

I should not have missed that.....but it was an accident.
