Roger. Frank, I would like to talk to you for a minute or two about the AUTO OPTICS funnies that you have been seeing throughout the mission. Over.

Roger. The problems you have run into so far are due to some unknown source, probably EMI or the like loading your CMC trunnion cell which is now 91, so it doesn't really represent your true trunnion angle. Now this loading problem we don't feel implies any decrease in the reliability in your CMC at all. We think that the best way to circumvent the problem is to cycle the OPTICS ZERO switch first to OFF and then ON prior to using the optics for any purpose. And with that procedure, I think you probably won't have any more problems. Over.

Roger, Jerry. Understand. I do notice one difference. We did preferred REFSMMAT's. The first we had trouble with; the last one worked out as expected. I noticed for the first one that when the option came up, it was for nominal option, whereas for the very same procedure for this last REFSMMAT change, we got … preferred REFSMMAT option. …

Roger. We went through the charts and got exactly the same answer as you got. Looks like your procedure is very good; looks like it was real good head. You remembered to average out the velocity. We also went ahead and computed the problem to verify the chart and got a good solution. Over.

Roger. On your question about the option: PROGRAM 40 sets the preferred flag such that the next P52 will come up option 1, subsequent alignments after that come up option 2. Over.

Roger. Understand. So 40 will have to come up with a TIG burn with an option 1 for us.

Roger. Now concerning your restart that happened in lunar orbit, for the peace of mind of the computer people and the MIT folks, we have a question. Did VERB 34 ENTER to a flashing VERB 51 in P22 cause your restart? Over.

Apollo 8, this is Houston. It is about time for us to start keeping track of some command module RCS temperatures; so when you get a chance, we'd like the reading now, and we'll try to repeat it about every 8 hours or so.
