Observing Summary:

First half of the night went smoothly.  Then I started getting errors in Prospero.  See below.
I had a sequence of exposures but it crashed in the middle.  The error message said that Prospero was trying to write to the same file.
When that happened it wrote to a file with a different filename.  I changed the filename and got the same errors.  I restarted Prospero and got the same errors.
I noticed that in Prospero Status  IC: DOWN  so I restarted again.  Same errors but I was able to do 1-5 exposures at a time (i.e. go 5)
with it crashing only sometimes.  I don't think I lost any data.

 DONE: Exposures finished.
 *** Exposure Completed ***

Error: Command returned error
 WARNING: could not update NEXTFILE and LASTFILE.
 Problems with the filename command.

I closed early because I noticed the 4m was closed due to high humidity.
