[Aavso-sid-list] Trace of NPM for possible GRB 090307

[Gary Myers]

Last night a GRB alert came in on my cell phone via the HEN network, GRB 090307. I looked at my trace of NPM and saw a significant spike that started at 0342 UT and peaked at 0346 UT, close to the burst time of the notice. Plotted the burst on Xephem and it originated from the constellation Scorpius. From my location this spike is almost two hours after sunset. I think this could be just the erratic night propagation. Although during the past week, my sunset to night patterns didn't have any voltage jumps like this progressing into the night. Maybe someone else who is monitoring may have seen something simular.  

Here is the AAVSO report on GRB 090307:
