U Gem eclipse ephemeris Several observers have reported a slight brightening (~13.6 mag) of U Gem. This would evolve into a full outburst. Observations of eclipses during the rising phase of an outburst is very important. Please observe them if conditions allow. An attempt to detect spiral features by time-resolved spectroscopy is also encouraged.
