[GCN OPS NOTE: Due to a processing problem at the GCN end, this circular was delayed in distribution (as were others, which see). It was received at 00:34:58 UT 05 Jul 99. It was received before GCN#362. Also, please note that the problem seems to be due to a problem with the gcncirc@lheawww.gsfc.nasa.gov account. Until I can resolve this problem with the System Administrators during tomorrow's normal business hours (today is a National holiday), please send any future notices to the gcncirc@lheawww account AND to the gcncirc@gris1.gsfc.nasa.gov, i.e. the account name is the same but a second host machine has been added. The second account@host is also working.]
