The mailer has formatted the previous circular in an almost un-readable
way. Below the text, I hope it will be readable this time. My apologies,
Michel
A. Klotz, M. Boer (CESR/OMP/CNRS), and J.L. Atteia (LAT/OMP/CNRS), on
behalf of the TAROT collaboration communicate:
Following our first analysis (Boer et al., GCN #1408), we performed a
refined analysis of the images acquired by TAROT after the alert sent by
HETE for GRB 020531 (Ricker et al., GCN #1399). �Within the IPN error
box we find a 3 sigma excess, elongated in the direction of the
telescope aberration, at the following position: RA = 15h15m12s, DEC =
-19�24�33�, with an error box of 7 arcsec, and a magnitude of 17.5.
Though this possible source is close to CXOU J151514.1-192428 (source #
56 in Butler et al., GCN #1415) both sources seem different.
�
In addition, the exposures taken by TAROT started at 01h54m28s UT, 6s
after the alert was sent by the GCN (and not 50s as mentioned in the
earlier circular).
