collaboration, report:
We have observed the error box of GRB 020819 with the CCD camera in
the JKT at La Palma on August 19/20. The filter was R Harris. We
obtained three sets of exposures at the beginning (2250 sec), middle
(3000 sec) and end (2250 sec) of the night. The limiting magnitude is
about R~22 for the first epoch.
We detect the OT candidate reported by Henden et al (GCN 1510) at
magnitude R ~ 21, but it does not fade from the beginning (UT ~ 23.814
hours) to the end (UT ~ 5.365 hours) of the night.
