I submitted a few observations of V380 Oph and I would appreciate a second look. It appears to be increasing in magnitude but I was worried that something was wrong with my observations since they are out of line with the recent past. I have submitted other observations of other stars which are in line. They are listed as SJMJ. Will obviously delete them if you find something anomalous with my submissions.
Alert Notice 841 requests coverage of VY Scl in support of HST Target of Opportunity observations scheduled for November 17 UT. Please see the notice for details and observing instructions.
