How long is a Munar day? (or night)

[Kerba Fett]

While I was off doing other things my dayside Mun operations became my nightside operations.

This is sort of a problem for my solar powered lander as well as my solar powered kethane miner.

So how long do I need to wait for the sun to come up?

According to the Wiki the Mun's Siderial Rotation Period is 138 984.38 s or 1 d 14 h 36 m 24.4 s

Note that the solar day is a little longer, because of Kerbin's orbit round the Sun. The solar day is the same as the synodic orbital period, since the Mun is tidally locked to Kerbin, and that's 141115s.
