Well, it got worse. Up to 2."35. Shortly thereafter the dome was closed
when the humidity exceeded 90%. Well, 94% and Mauricio says it's 6% too
low. Outside, there are waves of fog; the attenuation length is maybe 15
m, so little starlight gets through. I've spent nights like this at the
Lick 1-m.
Rob went off to sleep off a headache, leaving Eric and me with the
headache in the control room. At least we aren't logging useless data now.

All that time I spent last year complaining about the seeing? I didn't
realize how good I had it.
The *best* has been about 1.3. It's averaged about 1.5. At the moment
it's 1.6-1.7. This is pretty awful, and not generally useful for the
purposes to which we intend to use this data.
It's clear, at least, but that is small consolation with as bad seeing
as we have.
Hopefully it will be better during the next two days. If so, we will
make sure to get enough depth in I in the deep field, before doing any
R.
