TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3144 SUBJECT: GRB050326: delayed XRT observation DATE: 05/03/26 15:06:30 GMT FROM: David Burrows at PSU/Swift D. N. Burrows, S. Hunsberger, S. Kobayashi (PSU) and A. Moretti (INAF-OAB) report on behalf of the Swift XRT team: GRB 050326 was discovered by the Swift BAT instrument at 09:53:55 UT today (Markwardt et al. 2005, GCN 3143). The burst was within the Swift Earth constraint and observations were delayed by nearly an hour. When the XRT observed the field at 10:48:13 UT, there was no afterglow strong enough for an on-board centroid determination (which is normal when we observe this long after the burst). Unfortunately, this burst occurred during the daily 6 to 7 hour period when Swift is out of contact with the ground station, so we cannot perform ground analysis to search for an X-ray afterglow until about 19:00 UT. We will issue an updated GCN Circular once we can process those data.
