GRB 980703: BATSE Observations
R. M. Kippen (University of Alabama in Huntsville) reports on behalf
of the BATSE GRB team:
GRB 980703 was detected by BATSE on July 3.182468 UT as trigger number
6891. The event consisted of two pulses, each lasting approximately
100 s, with a total duration of about 400 s. The first pulse had
significant sub-structure, whereas the second, weaker, episode was
relatively smooth. The burst's peak flux (50-300 keV; integrated over
1 s) and fluence (>20 keV) are 2.42 (-/+ 0.06) photons cmE-2 sE-1 and
4.59 (-/+ 0.42) x 10E-5 erg cmE-2, respectively---ranking it in the
top 20% (5%) of the BATSE burst flux (fluence) distribution. The
average spectral hardness of the burst, as estimated by the ratio of
100-300 keV counts to those in the 50-100 keV range, is H32 = 1.05
(-/+ 0.02), which is average for events of this long duration. The
BATSE burst location is consistent with those measured by RXTE-ASM
(GCN/XTE Notices) and BeppoSAX (GCN 127). A location sky-map and
lightcurve for this event (and other notable bursts) are available at
the BATSE Rapid Burst Response world-wide-web site:
