The star is now over magnitude dimmer than in late January, 2000. From the lightcurve the deep eclipses that occur every 1.5 hours are easily detected. Also the dimming of star is evident after the eclipse.
Dots indicate individual brighness measures and continuous line is average of three measures.
The red points are magnitudes of a reference star. The vertical lines shows the error limits of each measurement. The zero point of magnitude scale was determined by a field star that brightness was measured during the January 24,2000 observation . The big variations of magnitude at the end of the observing run is caused by lightening dawn sky and fogging of correcting plate.
