Clouds!

Try overhead...

Above spectra useless.  OK, watch bright star and wait...supposed to be better later.

Cloud situation improving...try again.

Clouds for early exposures, but spectra get better at end

Temperature rising in dewar!  Stop to refill... This is cause of increased noise.
Data still looks good and useful.
