Problem(s) Encountered:

At the beginning of the night we had an issue with prospero, i.e.

prospero didn''t start an exposure. After re-starting prospero,

caliban and IC the problem was still present.

Solutions:

We called Rick Pogge

who could diagnose the problem from Columbus and he found that the

problem was most likely caused by the use of the 1k subframe which

should be avoided.
