I've been up in the dome trying to figure out some things about the way the Spar is guiding, so image occulting is going to change now and then.

So I wiggled the connections to the ethernet transceivers while trying to "ping" Kii and Nene until the ping got through. Both Kii and Nene observing programs crashed again until I positioned the ethernet transceiver so that there wasn't any strain on the cables. I marked the cable that appears to have a flaky BNC connector on it. COMMENT: Tue Jun 17 18:49:40 GMT 1997 From my Spar guider and MKIII O1 guider testing it looks like the Spar is guiding very well but the range of the MKIII O1 guider is insufficient (due to those missing teeth on the Driving Gear) to keep the sun well occulted throughout the day. We either have to pick a time that we want good guiding (currently adjusted for after 2100 ut) or we have to adjust the Spar guider throughout the day and then adjust the dPMon occulting as necessary, I'll try this latter technique first.

DPMON COMMENT: Tue Jun 17 19:20:43 GMT 1997 I had to readjust the occulting due to the change in Spar guiding. MKIII COMMENT: Tue Jun 17 19:21:11 GMT 1997 Occulting looks very good now. COMMENT: Tue Jun 17 19:37:19 GMT 1997 Extended the dome slot. After repointing on the sun I found that I had to adjust the Spar guiding again so that the MKIII O1 guiding wouldn't be at a limit. When the sun was blocked by the dome the MKIII guiders took off and the N-S guider (which is the one with the bad gear) got out of adjustment due to gear slippage, this explains why Donna noticed that the "smudge" was occurring just after I adjusted the dome slot because that is when the O1 guider lost its guiding center. So we will have to adjust the Spar guiding after the dome slot extensions each day, and probably at least one other time at the start of the day once the Spar is guiding on the sun. Adjustments to the N-S adjusting screw are small, about plus or minus 1/4 revolution, and the MKIII O1 guiders react fairly quickly once you get the right screw position, so this procedure takes one or two minutes at most. MKIII COMMENT: Tue Jun 17 19:59:24 GMT 1997 I noticed that the Y-axis readout needle was pegged at the top of the scale, I went up into the dome and saw that the image was too far South on the occulting disk. I adjusted the Spar guiding again to improve this occulting.

Very noticeable, but maybe this is due to irregular O1/Spar guiding?
