of the AAVSO International High Energy Network:
We observed the afterglow (Rykoff et. al., GCN 3723) for
the Swift burst GRB 050801 (Band et al., GCN 3725), using
the 30cm telescope plus ST-7XME CCD camera of Bronberg
Observatory. Using the UCAC2 star at 13:36:40.87
-21:55:58.6 as having a derived Rc magnitude of 14.5,
we obtain the following photometry:
UT / CR mag
19:03.0 17.5
19:05.5 17.7
19:08.0 17.9
19:10.5 18.1
19:14.5 18.4:
Uncertainty in timing : 30sec absolute, 10 sec relative
Uncertainty in magnitude : 0.3 in accuracy, 0.1 in precision
No further observations are planned.
