Also, it would seem Major Klutz and I are in different instances - I've never seen anyone on the moon - which is probably a good thing. It means the moon speed is consistent in different instances and not some glitch in one or the other.

We have a party started here. Still to dark to see much. The moon is still 6.58Mm away
Update: Moving painfully slow now. Still 6.35 Mm away an hour later

While I've been waiting, I've been doing some m-a-t-h-s 
2c is 0.72Ls from the gas giant (orbital radius). Its orbital period is 1.4days. Neither of these numbers are very precise, but they work out to an orbital velocity of 11,212m/s.
The closing velocity between 2b and 2c that I've been measuring has ranged from 76m/s up to about 160m/s. Put another way, the closing velocities are varying between 0.76% and 1.43% of the orbital velocity.
Note that I'm pretty sure the closing velocity is still slowing down right now - 76m/s won't be the minimum (edit: it is). The 160m/s I saw yesterday appeared to be a peak - I measured 158m/s at the start of my 12 consecutive measurements, got ~160m/s in the middle, and ~158m/s again at the end.
Doing some Googling on the eccentricity (0.001 - not very precise) the ratio between vmin and vmax is 0.998.
Taking the two extremes of orbital velocity we have seen: 160-76=84m/s difference, split that against the average orbital velocity: 11212+/-42 is 11170 and 11253m/s. The ratio of those is 0.9926.
Given the inaccuracy of the in-game numbers, this seems to be ball-park correct to me.
Every time I take a close look at the stellar forge, I get very impressed - good work Frontier! [up]

Looks like we have another commander on the b moon right now. And it looks like the lights are on over there.

Speed Update: at 04:22:49 it's exactly 6.00 Mm away.
Closing 0.1 Mm in 1303 seconds or a speed of 0.0046048 Mm/minute. 76.74m/s
Even slower than before. And still very dark.
Update: Still 5.46 Mm at 06:18. Gotta be at least 10 hours left even if it speeds back up to .5Mm/hr
Gotta get some sleep now, back in the morning.

Currently sitting at 1000km from the surface of C on the B-C line.
Current stream:
[video=youtube;PmGWhg64m_g]https://youtu.be/PmGWhg64m_g[/video]
At 08:43:18, the distance to B ticked over to 2.65Mm, making the distance between cores 4.997Mm +/- 0.01Mm.
At 09:20:45, the distance to B ticked over to 2.55Mm, making the distance between cores 4.897Mm +/- 0.01Mm.
That is 2247s to get 0.1Mm closer, which disagrees with what was found earlier. it also disagrees with the current 4.21Mm distance to C from the tangent point above planet B (orbit of C passes 131km above the surface of B).
At 09:42:31, the distance to B from the tangent point ticked over to 4.20Mm.
At 09:57:40, the distance to B from the tangent point ticked over to 4.10Mm.
That is 909s to move 0.1Mm (110m/s)

Well, 2b was starting to dip well below the horizon. I decided that was because it was getting too close, so I've moved to 0,0.
It's also a bit brighter, so I've started my live stream ( https://gaming.youtube.com/watch?v=OuY8pffm-7w ).
I think because I'm more in line with the moons, the closing speed has increased to about 97m/s. At that rate the surface of 2b should be where I am in about 7hrs, but my spreadsheet estimates are trending down right now, so it could be sooner.

Speed Update: Closed 0.10 Mm in 999 seconds (16.65 minutes)
Speed is 0.006006 Mm/min or 0.360360 Mm/hr or 100m/s
It's speeding up now
At this rate we have 411 minutes to go or ~6.8 hours
At least the lights are back on now.

The boundary between the two moons' gravity fields (where the surface display switches from one moon to the other) is currently 783km from the surface of moon B, and moving at about 60m/s. That would give about 3.6 hours until the moons touch.
I'm on moon B right now. Tried to get as close as possible to the ground zero, time will tell if I succeeded.
At least now the moon C is pretty much in zenith at my position.
Game time 11:32 the distance from my position to moon C center is 2.46 Mm, making distance surface to surface 1.36 Mm.

It's getting tricky to fly. I took off from c to thread the needle between the two moons in supercruise, take a look at the orbit lines and find a better place to park.
When I tried to land again, I came out of glide on the c moon and my speed indicator showed zero but I was moving and the ground was coming up to meet me.
There was no way to land, so I jumped back into SC and tried again approaching from the back side and was able to land again on c
I tried to judge a good landing spot based on the orbit lines. I ended up at around 0 by -30

Was watching Bloody Nutters stream and he tried to meet up with me. Arrived at 2c but still in the frame of reference of 2b, and 2c rushed up to meet him
I was really tempted before that to supercruise to a different location, but I think I'll stay right where I am...

Yeah. I just saw Nutters was 1Kly away and wondered what happened. Checked his live stream and saw the crash.
Clearly the ground is real and you will collide with it. Strange that your altitude and glide all refer to the planet you're on but your relative motion reference can still be different.
Now I'm starting to worry that if the moon hits me during the collision, it's going to hurt.
You should be able to outrun it in any ship but integrating the right vector is tricky. The ground is moving up toward you and the surface is moving laterally. It'll be some tricky flying.
Video of my near death experience with the frame of reference. https://youtu.be/LPNw8kBGfKk?t=7m53s
If you are on the ground now, best to stay out of supercruise. If you take off back into SC or you're already in space, you might want to stay there.

A quick time lapse of the approach over the last hour.
I decided to observe from the air so I can move quickly when I need to and so I don't get crushed
I just hope my frame of reference doesn't change on me.

Last 0.40 Mm too 1051 seconds, making 0.1 Mm take 17½ minutes on average.
0.65 Mm to go making it about 1h 54min until surfaces contact (assuming constant closing speed).
EDIT: The moon B seems to rotate relative to moon C, I noticed a 15° drift of moon C from zenith in about an hour.
Making probably the 102 seconds for 0.01 Mm (17 minutes sharp for 0.1 Mm) my better estimate.
Going to relocate few degrees 'ahead' now.

Cmdr Bloody Nutter made it back in quick time after his close encounter.
And so we wait...
