I'm bringing up all the instrumentation and checking everything for problems. COMMENT: Wed Jan 19 18:10:43 GMT 2000 No observing until clouds clear away. Wed Jan 19 13:58:14 GMT 2000 CHIP Startup--Initializing new tape **LOW-L PROBLEM**: Wed Jan 19 18:31:56 GMT 2000 L00660 was popped out of drive #0 yesterday and replaced with L00662. L00661 had 2 files on it yesterday so I replaced it with L00663 in drive #1.

Their GPS time always differs from our WWVH time, right now it is 15 seconds fast, I double checked ours with WWVH and it is correct, I'll let them know. CHIP Gain COMMENT: Wed Jan 19 20:02:57 GMT 2000 Everything is back up and working correctly as far as I can tell.

The UPS is passing through power (bypass mode) but won't support a load if HELCO goes out again. The main symptom was that the display wasn't lit up, I tried several tests and determined that the Electronics Unit (EU) was bad. It probably has a sticky or stuck relay, this gave me a problem back in 2/4/99, and it always sounded strangely noisy when it did its automatic tests. The manufacturer, APC, is sending out a new EU which should arrive in 7 to 10 days. I won't restart the instruments due to clouds.
