----------------------------------------------------------------------------- Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Thu Jan 6 17:45:56 GMT 2000 Year: 00 Doy: 006 Observer: koon WEATHER COMMENT: Thu Jan 6 17:45:59 GMT 2000 Clear sky, wind=10 mph from the SE, temp=40 F. **MKIV PROBLEM**: Thu Jan 6 17:50:57 GMT 2000 Twice this morning the akamai window disappeared about one second after appearing upon powerup of akamai. I'm going to try observing without the akamai window present.

It worked OK for a while this morning but now it can't find it every time. I see the Home LED light at the right time but it is before the Bit #1 LED which just blinks right at the end of it's wedge as the encoding wheel rotates. This worked flawlessly yesterday afternoon, It may be due to thermal expansion or contraction of the something, it has been really cold in the mornings, especially with the wind chill. If I put the wheel in the correct position with a power supply the Bit #1 LED won't light until I remove and replace the Wheel Status board, even if I use a different board. This may mean that the HEI voltage is just below the threshold needed to set Bit #1. **GONG PROBLEM**: Thu Jan 6 19:35:53 GMT 2000 Still no reply from Jean at GONG, so I called Lana and gave her all the information about the xterm console login problem and the network slowdown and asked her to check if GONG network activities have changed in case they may be causing the slowdown. I mentioned how the TCP login manager on the GONG workstation wasn't responding, she said they installed TCP wrappers back in November during their PM trip but doesn't know of any new network changes. She'll check it out and call me back. **GONG PROBLEM**: Thu Jan 6 19:49:17 GMT 2000 Lana called back already, nothing unusual could be found, and she said I can try a workstation reboot now that everything has been checked. So I'm going to do that in a few minutes.

I asked Lana and she said Jean found a problem with the iraf stuff yesterday. So it appears they still aren't sure if they are back to normal. After the reboot our console still can't login to the workstation, no change. **PICS PROBLEM**: Thu Jan 6 20:28:59 GMT 2000 Manually moved the wheel using the power supply, no Bit #1 LED lit, went upstairs with a heatgun and heated the decoder/HEI area, the Bit#1 LED came on. Definitely a thermal problem upstairs. Will try moving the Bit #1 HEI next.

We were on the hub with GONG and may have been slowed down by their bandwidth usage or a faulty hub. Getting mail messages is much faster now. Thu Jan 6 21:25:24 GMT 2000 MKIV Start Patrol MKIV COMMENT: Thu Jan 6 21:26:10 GMT 2000 I forgot to restart the Patrol after the cal, just did it now, too much running around. **GONG PROBLEM**: Thu Jan 6 21:29:22 GMT 2000 The MLSO console now will connect to the shelter, new hub better. COMMENT: Thu Jan 6 21:29:53 GMT 2000 MLO image computer working, new hub better. COMMENT: Thu Jan 6 21:30:18 GMT 2000 Darryl is going back down to add the GONG shelter to the new hub, then we'll see if everyone (including NOAA) gets slowed down drastically. If so, then GONG is causing the problem, if not then the old hub is bad. One thing is for sure, the network connection is back to normal using this new hub. COMMENT: Thu Jan 6 21:46:12 GMT 2000 OK, we tried various combinations of hubs and cables and it looks like the old hub is intermittently slow. I'll ask GONG to send out a new one, until then we'll be on the new hub and they'll be on the old hub.

I started Patrol so I can get data (if nothing else) until it starts failing again. I need to try an adjustment when Bit #1 isn't being sensed. **PICS PROBLEM**: Thu Jan 6 23:34:34 GMT 2000 Patrol stalled at Init., doing Kill/Run to restart. Thu Jan 6 23:36:53 GMT 2000 PICS Start Patrol **PICS PROBLEM**: Thu Jan 6 23:43:51 GMT 2000 I forgot to mention that earlier I tried blowing air over the HEI in case dust had settled there but there was no change in the problem. Right now there are no symptoms of the problem and since the problem appears worse in the morning that would be the time to work on this, that's a drag after getting this close. It appears the problem is either that the inner HEI needs to be adjusted to see through the Bit #1 hole better or the HEI is defective and needs to be replaced.
