I've posted on http://ftp.nofs.navy.mil/pub/outgoing/aah/phot/wzsgeug.gif the U-band light curve from last night. As opposed to the steady decline, QPO and no real humps of 010818, the 010819 data shows a stable light curve with single hump and no decline. Each data point has a Poisson error of less than one percent, so most of the flickering is real. Forecast for tonight is mostly cloudy with thunderstorms. Clearing is expected towards mid-week; I may do one more run on WZ Sge when HST is observing on Aug 22 UT (06:12-12:01). Arne
