04 02 05 28
Jim Lovell (CMP): Okay. Sounds good. How is your Christmas, Jerry?
04 02 05 31
Jerry Carr (CAPCOM): Real good, Jim. Santa Claus struck last night before I came in here on the shift, and I guess we will finish off the unwrapping this morning when I get back.
04 02 05 45
Jim Lovell (CMP): Right. He was looking for a chimney on 103 here, but he didn't see any.
04 02 05 50
Jerry Carr (CAPCOM): (Laughter) You could have left the hatch unlocked for him.
04 02 06 08
Jim Lovell (CMP): I'll think about that one.
04 02 06 10
Jerry Carr (CAPCOM): Think real hard, Jim. EECOM says he could have slid down the steam duct.
04 02 06 37
Jim Lovell (CMP): Sounds good. About that time, Bill would have been boiling water.
04 02 06 53
Frank Borman (CDR): Hey, Jerry, this is Frank. What's up?
04 02 06 55
Jerry Carr (CAPCOM): Hi, Frank. Christmas morning has come at the Borman house. And the boys and Susan and your Mom and Dad all send their love. They say for you to stay in there and pitch. Over.
04 02 07 11
Frank Borman (CDR): Okay. Thank you. Please reciprocate for me.
04 02 07 16
Jerry Carr (CAPCOM): Sure will, Frank.
04 02 07 27
Jerry Carr (CAPCOM): Frank, when Bill wakes up, give me a holler. I've got a message for him, too.
04 02 07 35
Frank Borman (CDR): Okay.
04 02 15 23
Jim Lovell (CMP): Houston, Apollo 8.
04 02 15 26
Jerry Carr (CAPCOM): Apollo 8, Houston. Go.
04 02 15 31
Jim Lovell (CMP): Roger. Are the Guidance boys busy this morning?
04 02 15 41
Jerry Carr (CAPCOM): They say they are.
04 02 15 49
Jim Lovell (CMP): I just worked out an answer to move my landing longitude 6 degrees east. I just want to compare with what they've got based on the same burn time of 114 hours, based on the bias impact longitude determined from the P37 which is wrong. I've indicated that I need 600 foot per second DELTA-V_C burn plus, and my DELTA-V_X changes from a minus 11.6 feet per second. I'd like to have them verify that if I could.
04 02 16 29
Jerry Carr (CAPCOM): Roger Jim. Standby, and I'll see if they copied all that.
04 02 17 30
Jerry Carr (CAPCOM): Apollo 8, Houston.
04 02 17 34
Jim Lovell (CMP): Go ahead.
04 02 17 35
Jerry Carr (CAPCOM): The voice isn't too great right now, and the Guidance troops didn't get all of that. How about waiting about 2 or 3 minutes? We'll swap OMNI antennas, and then we should get good voice transmission from you and then repeat it. Would you, please?
04 02 17 54
Jim Lovell (CMP): Roger.
04 02 17 55
Jerry Carr (CAPCOM): Okay.
04 02 22 55
Jerry Carr (CAPCOM): Apollo 8, Houston. How do you read? Over.
04 02 23 00
Frank Borman (CDR): Loud and clear.
04 02 23 01
Jerry Carr (CAPCOM): Roger. We're reading you much better now. Jim can go ahead with his transmission to the guidance troops. They have one question before he starts. They would like to know what his GERU was at TIG, 114 hours. Over.
04 02 23 21
Frank Borman (CDR): Roger. Wait one. The GERU at TIG was plus 07972.
04 02 23 35
Jerry Carr (CAPCOM): Roger. Plus 07972.
04 02 25 07
Jerry Carr (CAPCOM): Apollo 8, this is Houston. We are ready to copy your data. Over.
04 02 25 14
Jim Lovell (CMP): Okay, Houston. Based on the P37 with minus MA solution, I got an impact longitude of minus 160.95. I biased it to get an impact latitude—longitude of 163.75. I wanted to change my impact point 30 degrees to the east, and I tried to determine what my P30 burn parameters would be to do this, and I got a DELTA-V_X burn of minus 11.6 and a DELTA-V_C of plus 600, DELTA-V_{Y of zero. Now that changed my previous DELTA-V_X burn from minus 50.2. I just want to know whether that meets with their approval.}
04 02 26 15
Jerry Carr (CAPCOM): Roger, Jim. We copy and will run it through the mill and give you an answer.
04 02 26 23
Jim Lovell (CMP): Roger.
04 02 49 35
Jerry Carr (CAPCOM): Apollo 8, Houston.
04 02 49 40
Frank Borman (CDR): Go ahead, Houston. Apollo 8.
04 02 49 42
Jerry Carr (CAPCOM): Apollo 8, this is Houston with a flight plan update.
04 02 49 48
Frank Borman (CDR): Go ahead.
04 02 49 50
Jerry Carr (CAPCOM): Roger. At 100 hours 30 minutes, change star number 02 from one set to two set. Over.

04 02 50 05
Frank Borman (CDR): Roger. Star 02 from one set to two set.
04 02 50 08
Jerry Carr (CAPCOM): Roger. Also, set number 2, set number 2, change star number 11 to star number 7. Over.
04 02 50 21
Frank Borman (CDR): Roger. Eleven to 7.
04 02 50 23
Jerry Carr (CAPCOM): Roger. Then after star set number 3, initiate PTC again; pitch 10, yaw 45. Over.
04 02 50 36
Frank Borman (CDR): Pitch 10, yaw 45.
04 02 50 38
Jerry Carr (CAPCOM): Roger. Then at 101 hours 30 minutes, delete the earth horizon settings. Over.
04 02 50 53
Frank Borman (CDR): 101:30, delete the earth horizons sightings.
04 02 50 57
Jerry Carr (CAPCOM): That's affirmative. The folks here are evaluating the thermal situation. Looks like you will be out of PTC rather at an extended period of time. That's the reason we have you initiating PTC again there around 101 as soon as you finish those three star sightings. We are still working on the—about the next 10 hours after 100 hours. We are looking at the thermal situation, and the star sighting situation, and we will be giving you more updates later on. Over.
04 02 51 32
Frank Borman (CDR): Roger. We don't have a thermal problem at all now, do we? All our indications here are normal in here.
04 02 51 40
Jerry Carr (CAPCOM): Roger. Everything looks okay. I think they're just kinda trying to look down the track aways.
04 02 51 47
Frank Borman (CDR): I'm all for keeping it that way.
04 02 51 50
Jerry Carr (CAPCOM): Roger.
04 02 51 53
Frank Borman (CDR): We deleted them.
04 02 51 55
Jerry Carr (CAPCOM): Okay.
04 02 56 53
Jerry Carr (CAPCOM): Apollo 8, Houston.
04 02 56 59
Frank Borman (CDR): Go ahead, Houston.
04 02 57 00
Jerry Carr (CAPCOM): 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.
04 02 57 11
Jim Lovell (CMP): Go ahead.
04 02 57 13
Jerry Carr (CAPCOM): 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.
04 02 58 01
Jim Lovell (CMP): 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. …
04 02 58 27
Jerry Carr (CAPCOM): Roger, Jim. Copy.
04 03 00 56
Jerry Carr (CAPCOM): Apollo 8, this is Houston with a comeback on your entry navigation calculations. Over.
04 03 01 05
Frank Borman (CDR): Go ahead.
04 03 01 07
Jerry Carr (CAPCOM): 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.
04 03 01 30
Jim Lovell (CMP): Roger.
04 03 01 33
Frank Borman (CDR): Thank you very much.
04 03 01 35
Jerry Carr (CAPCOM): You're welcome.
04 03 01 40
Jim Lovell (CMP): Now if we can get our state vectors to agree, we'll be in business.
04 03 01 45
Jerry Carr (CAPCOM): No sweat.
04 03 19 38
Jerry Carr (CAPCOM): Apollo 8, Houston.
04 03 19 55
Jerry Carr (CAPCOM): Apollo 8, Houston.
04 03 19 59

Jerry Carr (CAPCOM): Roger, Frank. Is Jim listening?
04 03 20 06
Jim Lovell (CMP): Listening.
04 03 20 08
Jerry Carr (CAPCOM): 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.
04 03 20 27
Jim Lovell (CMP): Roger. Understand. So 40 will have to come up with a TIG burn with an option 1 for us.
04 03 20 34
Jerry Carr (CAPCOM): 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.
04 03 20 56
Jim Lovell (CMP): Yes. That sounds like it was it.
04 03 20 59
Jerry Carr (CAPCOM): Roger. Thank you, Jim.
04 03 21 03
Jim Lovell (CMP): That must be a “no, no”.
04 03 21 08
Jerry Carr (CAPCOM): Yes, Yes. That's a “no, no”.
04 03 21 14
Jim Lovell (CMP): That almost caused an unscheduled EVA, too.
04 03 22 29
Jerry Carr (CAPCOM): Apollo 8, Houston. BIOMED switch center. Over.
04 03 22 49
Jim Lovell (CMP): Three, two, one -
04 03 22 51
Jim Lovell (CMP): MARK.
04 03 22 52
Jerry Carr (CAPCOM): Roger. Your mark.
04 03 50 59
Jerry Carr (CAPCOM): Apollo 8, Houston.
04 03 51 03
Frank Borman (CDR): Go ahead.
04 03 51 06
Jerry Carr (CAPCOM): 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.
04 03 51 22
Frank Borman (CDR): Okay. We'll get them for you right now.
04 03 51 24
Jerry Carr (CAPCOM): Roger.
04 03 51 32
Frank Borman (CDR): You want the motor off the test meter, right?
04 03 51 37
Jerry Carr (CAPCOM): That's affirmative.
04 03 51 48
Frank Borman (CDR): The 5C is pegged high.
04 03 51 55
Jerry Carr (CAPCOM): Roger. 5C pegged high.
04 03 51 56
Frank Borman (CDR): 5D is pegged high.
04 03 51 58
Jerry Carr (CAPCOM): Roger. D, high.
04 03 52 00
Frank Borman (CDR): So's 5D. 6A is high; 6B is high; 6C is 5 volts; 6D is pegged high.
04 03 52 27
Jerry Carr (CAPCOM): Apollo 8, Houston. Roger. Understand. 5C and 5D are pegged high; 6A and 6D are pegged high; 6 Charlie is 5 volts; and 6 Delta pegged high. Over.
04 03 52 42
Frank Borman (CDR): That's Roger.
04 03 54 56
Jerry Carr (CAPCOM): Apollo 8, Houston.
04 03 55 01
Frank Borman (CDR): Roger. Go ahead.
