As you will gather from looking at the web page with the observing log,
this was an extrememly disappointing night at Keck. We tried
progressively brighter candidates because the seeing and cirrus were
making it difficult or impossible to get any signal at all for faint
objects. The only real SN spectrum data was for C02-000, which I
believe looked like a fine z ~ 0.25 SN (I don't have it front of me
now), but this is hardly what we were trying to get tonight.
We also continued to be plagued by astrometry and acquisition
problems. We can't tell for sure if we have reliable offsets and
offset stars (the Subaru team using their astrometry did not get all the
same offsets as on our latest finding charts). We also don't find
complete closed-loop reproducability for our multi-star fits of the
guider field (or ESI direct image) to the finding chart FITS image.
Well, the first thing to hope for is much better weather this next
night. Then we'll have to think a little more about our observing
order and strategy (particulary after some of us are a little more
awake).
Goodnight/goodmorning
