REC 100 2 2246-2313 *KP site computer appears to have crashed. SW 100 27 2308 MK tape repositioned to correct location. 2311 *Rebooting KP. 2313 *KP tape is correctly positioned so the astronomical data may be okay, but it autostowed at some point during the crash period so the data may not be any good after all. 2323 %Raining at SC. 2335 J Nowicki operating. 0000 Date is 1997AUG18/230. vclock okay. 0047 Last several tape readback checks all look fine. 0100 %Wea: PT raining, heavy clouds. 0208-0222 *LA auto stow.
