COMMENTS: Optical counterparts to GRBs have ONLY ONCE been observed COMMENTS: less than a few hours after the event. We claim no COMMENTS: ownership of any results that follow from this report. COMMENTS: We'd like to encourage you to take advantage of this COMMENTS: opportunity to make the next big discovery. COMMENTS: COMMENTS: Below are quanities to aid in evaluating this alert. COMMENTS: Values of chi-sq. less than 1.15 and S/N > 6.0 are good COMMENTS: indicators of a strong, real detection.

They are COMMENTS: not definitive, but we are confident that there *will* be COMMENTS: something new of Astronomical interest in this error box. COMMENTS: COMMENTS: BATSE reports no recent GRB trigger. COMMENTS: COMMENTS: SSC 1: No short-term variability detected in ASM MTS data.
