Got multiple module 18886 100 23 slow errors on pack in bank B when pack in bank A was pulled (pack in bank A was "full" with only 75% used). Site tech is going to reboot Mark5 & VME. 1815 New operator: T. Perreault 1927 KP wea: low overcast, very light rain 1954-2001 *PT autostowed. Power glitch. Repointed. COM 100 7 2008-2016 *KP autostowed. Power glitch. Repointed. COM 100 8 Power glitch again before reaching source. Autostowed. Site techs repointed. 2107 %FD wea: heavy thunderstorms in area, getting close to the site 2108-2119 *PT autostowed. Power glitch. Repointed. COM 100 11 2139 New operator is Jim Ogle. 2142 *Raining at FD. 2245-2245 *FD autostowed, power glitch proably due to the WEA 100 1 bad weather in the area. Repointed. 2255 OV reports clear skies. 2314 MK reports clera skies. 0000 Date is 2006AUG31/243. 0111 %HN ellipsoid is being flagged on VLDIS but I don't see anything wrong with it in the checker messages or on screens. 0124-0127 *OV AZ#1 armature overcurrent fault. Briefly ACU 100 3 disabled the AZ axis to clear fault then repointed. 0127 HN ellipsoid no longer being flagged on VLDIS. 0545 New operator is Heidi Gerhardt. 0554 FD intermittant loss of communication with the COMM site. Dial backup was attempted, still no comm with the site. Possible issue with the router. Observation continued during the periods of loss of communication unless otherwise noted. 0735-0754 *FD communication down, stale link, dial up. COMM 100 19 reboot using site sensophone to try to get ant to respond 0826-0932 *FD taking out of observation due to very bad com COMM 100 66 Put back in to see if com will hold up. 1326 New operator: T.
