GCN Circular 85

Alain Maury (OCA), D. albanese (OCA), and Michel Boer (CESR/CNRS)
report:

"We obtained images of the localization of GRB 980519 (GCN circ 75) as
reported by BeppoSAX team, on May 19 and 20 using the 90cm Schmidt
telescope of the Observatoire de la Cote d'Azur.
The optical transient reported by Jaunsen et al. (GCN Circ. 78
Not found
 
 
) is
clearly detected and fading on images taken at UT May 19.862556,
20.076519, 20.964261 on unfiltered exposures.
The corresponding magnitudes are
May 19.862556           19.06 +- 0.26
May 20.076519           19.81 +- 0.37
May 20.964261           22.06 +- 0.76

The power-law slope decline is roughly 2.0, which, given the
uncertainties is consistent with the value reported by Djorgovski et al.
