After I "quit" the last problem noted in the log the screen started showing an apparently endless list of "counter timeout" messages. At first I waited, hoping this was something that would clear up, it didn't. I opened another xterm window and killed the Run task to get control again. Then I tried Run several times and would end up in the same position as the first problem I mentioned where you have to press q to quit. The telescope never pointed at the sun correctly. Then I tried reseting the PC and tried Run again, that too would lead to having to type q to get out of the endless loop, but the telecope seemed to point closer to the sun. Then I tried cycling the rack power and then tried Run, that too lead to the endless loop. PSPT COMMENT: Sun Apr 5 20:25:58 GMT 1998 The last time I tried Run I noticed a message scroll by on the PC screen that said that the miiror servo was off, along with a few other things that were off. I'm not sure if this is normal at that point of the startup but the green LED on the front off the mirror servo rack doesn't come on either. I sent e-mail asking Haosheng to call me up so I can ask him a few questions, in the mean time I'll keep trying different things. PSPT COMMENT: Sun Apr 5 20:57:43 GMT 1998 Still no luck with this. It looks like everything is working OK but the telescope is pointing to the wrong place. It points to the coordinates that are requested on the screen but that isn't where the sun is. Its as if the ephemeris is wrong because it will point to where the sun was an hour or two earlier. I used Obs to check the time and it is correct so it isn't pointing to the wrong place due to the wrong system time. The only other thing I can think of is maybe the RA and Dec initializations haven't worked the last 6 or 7 times that I tried Run.

Again the telescope doesn't point to the correct position but it points where it is told to point. Also, regarding questions I had earlier, I did see the mirror servo light go on and off when it should have and those messages I saw about things being off are apparently normal and are shown whenever those devices are turned off as scheduled. So the most likely problem is the ephemeris calculations, tomorrow is the start of daylight savings time but I doubt that was factored in anywhere since that doesn't affect GMT which is what the ephemeris probably uses. Secondly I guess the initialization of the RA and Dec could be incorrect but I doubt it. I can't go any further with this today unless Haosheng calls. Maybe if this is an ephemeris problem it will clear up with a change in date, as some of the old LOWL problems did. COMMENT: Sun Apr 5 21:27:43 GMT 1998 I extended the dome about 20 minutes ago, late due to PSPT problems distracting my attention.
