Observations of U Gem needed now
Details will be forthcoming in an AAVSO Special Notice, but visual and multicolor observations of U Gem are needed now through at least December 11. HST/COS will be observing U Gem on 2013 December 7, now that the recent outburst is over, and it is essential to have good coverage from AAVSO observers. These HST observations are a continuation of the campaign announced last year in AAVSO Alert Notice 475 and followed up on in AAVSO Special Notices #327 and #328.
Good observing - Elizabeth Waagen, AAVSO HQ
