Jennings (IGPP, UCR visitor)\n\nreports that it intends to repeat observations of IPN/RXTE error box\nfor GRB990506 for comparison with data taken 7 May 1999 UT (for\npointing and observational details see GCN 294).  The data taken 7 May\nreach an R magnitude of approximately 23-24, and we expect to reach\nsimilar limits tonight.  If any variable sources are detected, we\nexpect to release the position and approximate photometric measures via\nGCN by 0700-0800 UT 8 May 1999, which may be sufficient notice for\nobservers located further west.",
