Hi,
The SDFe was observed with Suprime-Cam.
Tonight the weather is not very good at the Mauna Kea.
As you see below, the observation started under good condition,
but eventually clouds crossed over, and the guide star was lost
once. There are 48min exposures, but 12min were not very effective.
Seeing was reasonably good, and probably we can use this data set
for search. We won't have any more data for SDFe and SDFw this time.
We will send the data to LBL.
Summary
7sec good 0.55arcsec
4minx8 good 0.6arcsec
4minx3 cloudy/hazy 0.8arcsec
3minx1 probably good 0.6arcsec
