03 04 57 00
Buzz Aldrin (LMP): No, that's fine. I just wanted to confirm that. Until 79 10, then we'll breeze around here in orbit.
03 04 57 07
Bruce McCandless (CAPCOM): Roger. And we've got an observation you can make if you have some time up there. There's been some lunar transient events reported in the vicinity of Aristarchus. Over.
03 04 57 28
Buzz Aldrin (LMP): Roger. We just went into spacecraft darkness. Until then, why, we couldn't see a thing down below us. But now, with earthshine, the visibility is pretty fair. Looking back behind me, now, I can see the corona from where the Sun has just set. And we'll get out the map and see what we can find around Aristarchus
03 04 57 54
Neil Armstrong (CDR): We're coming upon Aristarchus right now —
03 04 57 55
Bruce McCandless (CAPCOM): — Okay. Aristarchus is at angle Echo 9 on your ATO chart. It's about 394 miles north of track. However, at your present altitude, which is about 167 nautical miles, it ought to be over—that is within view of your horizon: 23 degrees north, 47 west. Take a look and see if you see anything worth noting up there. Over.

03 04 58 34
Neil Armstrong (CDR): Both looking.
03 04 58 36
Bruce McCandless (CAPCOM): Roger. Out.
03 05 03 01
Buzz Aldrin (LMP): Houston, 11. It might help us a little bit if you could give us a time of crossing of 45 west.
03 05 03 09
Bruce McCandless (CAPCOM): Say again, please, 11.
03 05 03 23
Buzz Aldrin (LMP): You might give us a time of crossing of 45 west, and then we'll know when to start searching for Aristarchus.
03 05 03 32
Bruce McCandless (CAPCOM): Roger. You'll be crossing 45 west at 77 04 10 or about 40 seconds from now. Over. Thirty seconds from now.
03 05 03 45
Buzz Aldrin (LMP): Okay.
03 05 04 50
Bruce McCandless (CAPCOM): Apollo 11, when we lose the S-band, we'd like to get OMNI Charlie from you. And update my last, that 77 04 was the time when Aristarchus should become visible over your horizon. 77 12 is point of closest approach south of it. Over.
03 05 05 14
Buzz Aldrin (LMP): Okay. That sounds better because we just went by Copernicus a little bit ago.
03 05 05 18
Bruce McCandless (CAPCOM): Roger. We show you at about 27 degrees longitude right now.
03 05 05 25
Buzz Aldrin (LMP): Righto.
03 05 07 07
Buzz Aldrin (LMP): Houston, when a star sets up here, there's no doubt about it. One instant it's there, and the next instant it's just completely gone.
03 05 07 16
Bruce McCandless (CAPCOM): Roger. We copy.
03 05 09 21
Bruce McCandless (CAPCOM): Apollo 11, this is Houston. We request you use OMNI Charlie at this time. Over.
03 05 09 29
Buzz Aldrin (LMP): Okay. Going to OMNI Charlie.
03 05 09 32
Bruce McCandless (CAPCOM): Roger. Out.
03 05 11 57
Buzz Aldrin (LMP): Houston, Apollo 11.
03 05 12 01
Bruce McCandless (CAPCOM): Apollo 11, this is Houston. Go ahead.
03 05 12 06
Buzz Aldrin (LMP): Roger. Seems to me since we know orbits so precisely, and know where the stars are so precisely, and the time of setting of a star or a planet to so very fine a degree, that this might be a pretty good means of measuring the altitude of the horizon …
03 05 12 32
Bruce McCandless (CAPCOM): Roger.

Michael Collins (CMP): Hey, Houston. I'm looking north up toward Aristarchus now, and I can't really tell at that distance whether I am really looking at Aristarchus, but there's an area that is considerably more illuminated than the surrounding area. It just has—seems to have a slight amount of fluorescence to it. A crater can be seen, and the area around the crater is quite bright.
03 05 13 30
Bruce McCandless (CAPCOM): Roger, 11. We copy.
03 05 14 23
Buzz Aldrin (LMP): Houston, Apollo 11. Looking up at the same area now and it does seem to be reflecting some of the earthshine. I'm not sure whether it was worked out to be about zero phase to—Well, at least there is one wall of the crater that seems to be more illuminated than the others, and that one—if we are lining up with the Earth correctly, does seem to put it about at zero phase. That area is definitely lighter than anything else that I could see out this window. I am not sure that I am really identifying any phosphorescence, but that definitely is lighter than anything else in the neighborhood.
03 05 15 15
Bruce McCandless (CAPCOM): 11, this is Houston. Can you discern any difference in color of the illumination, and is that an inner or an outer wall from the crater? Over.
03 05 15 34
Michael Collins (CMP): Roger. That's an inner wall of the crater.
03 05 15 43
Buzz Aldrin (LMP): No, there doesn't appear to be any color involved in it, Bruce.
03 05 15 47
Bruce McCandless (CAPCOM): Roger. You said inner wall. Would that be the inner edge of the northern surface?
03 05 16 00
Michael Collins (CMP): I guess it would be the inner edge of the westnorthwest part, the part that would be more nearly normal if you were looking at it from the Earth.
03 05 16 20
Bruce McCandless (CAPCOM): 11, Houston. Have you used the monocular on this? Over.
03 05 16 28
Buzz Aldrin (LMP): Stand by one.
03 05 17 59
Buzz Aldrin (LMP): Roger. Like you to know this quest for science has caused me to lose my E memory program, it's in here somewhere, but I can't find it.
03 05 18 08
Bruce McCandless (CAPCOM): 11, this is Houston. We're—we're hearing only a partial COMM. Say again please.
03 05 18 20
Neil Armstrong (CDR): I think …
03 05 18 41
Neil Armstrong (CDR): Houston, we will give it a try if we have the opportunity on next—when we are not in the middle of lunch, and trying to find the monocular.
03 05 18 51
Bruce McCandless (CAPCOM): Roger. Copied you that time. Expect in the next REV you will probably be getting ready for LOI 2.
03 05 19 09
Bruce McCandless (CAPCOM): So, let's wind this up, and since we've got some other things to talk to you about in a few minutes. Over.
03 05 19 19
Buzz Aldrin (LMP): Okay.
03 05 22 44
Bruce McCandless (CAPCOM): Apollo 11, this is Houston. Over.
03 05 22 49
Michael Collins (CMP): Go ahead, Houston.
03 05 22 53
Bruce McCandless (CAPCOM): 11, this is Houston. We're targeting—planning to make the LOI 2 burn now using bank A only. We'll have the PAD and everything for you next time around. Just trying to economise a little on bank B. Bank B is holding, though.
03 05 23 15
Michael Collins (CMP): Roger. Understand.
03 05 31 53
Bruce McCandless (CAPCOM): Apollo 11, this is Houston. Over.
03 05 32 02
Neil Armstrong (CDR): Go ahead.
03 05 32 04
Bruce McCandless (CAPCOM): 11, Houston. In order to improve the communications a little bit here, we'd like to try to get you on the high gain antenna. We're recommending a pitch angle of 0, yaw 355—I say again 355, the track switch to MANUAL, and wide beamwidth. Over.
03 05 32 42
Neil Armstrong (CDR): Okay. You ready to switch to high gain now?
