Observation
of the bright Gamma-Ray Burster GRB 030329
On March 30, 2003 we
succeeded in observing GRB 030329, an extremely
bright Gamma Ray Burster that was discovered with
the HETE satellite on Mar. 29.484 UT and that is
located at R.A. = 10h44m50s, Decl. = +21o31'18"
(equinox 2000.0).
This was the
brightest GRB ever detected by HETE and ranked
among the brightest 1
percent of all GRBs previously detected. The
object was intensively monitored by both
professional and amateur astronomers, in
multiple wavelengths. It reached a
maximum brightness of about V 12.5.
We managed to obtain the image at right on
March 30, 2003 at 23h56m UT. This is nearly
1.5 days after the discovery of the burst,
and still the object was clearly visible in
our unfiltered CCD image. It's estimated
magnitude was mag 16.8. |
