The first supernova candidate we tried tonight was the bright candidate
-001 (which is the same as -027), with magnitude i'_AB ~=23.2, and ~100%
increase. The acquisition software (by Robert Quimby, with
contributions from Alex Conley and Lifan Wang, and debugging by Greg
Aldering) worked quite well. The half hour exposure we took showed a
nice Type Ia-like SN at z ~ 0.57.
We had just aquired are second target, -019, when we got word from
Mamoru and Naoki's colleagues that they had just succeeded in obtaining
at photo-z for it -- and they estimated z = 0.6 -- 0.8. So we aborted
that candidate (we can try some other time to confirm this z, if we have
enough telescope time), and moved on to -026, which we are now
integrating on.
We think the seeing is around 0.7".
