It was reopened at 03:20. The observers were myself for PU01 and Dick Henry, Karen Kwitter, and Sarah Kate Mae for UW08. The sky started to cloud up with thick cirrus soon after it got dark. At least most of the observing was spectroscopy. Although some time was lost to clouds, the UW observers were able to observe two more objects after we reopened. OBSERVER COMMENTS comments are being emailed to me - I'll have to send them out when I get them.
