Subject
Chandra observation of the IPN error box of GRB021201 (short/hard)
Date

From
Kevin Hurley at UCBerkeley/SSL <khurley@sunspot.ssl.berkeley.edu>
K. Hurley, T. Cline, M. Feroci, P. Li, F. Frontera, E. Mazets, S.
Golenetskii, I. Mitrofanov, G. Ricker, and J.-L. Atteia, on behalf
of the Chandra target of opportunity for IPN short bursts collaboration,
report:

Chandra observed the error box of the short/hard GRB021201 (GCN 1719)
for approximately 21 ks starting at 23:10 on December 9.  A very
preliminary analysis indicates that about 26 sources are present in
the Chandra field.  They are listed in the table below.  One of these
sources (#10) is inside the IPN error box.  A map has been posted at
ssl.berkeley.edu/ipn3/021201.  A second follow-up Chandra observation
will take place in several weeks to determine whether this or any other
source in the field displays fading behavior.
