Dear HT Cas observers,
HT Cas seems to have stopped fading. The post-outburst object is now
staying about 1 mag brighter than its "high-state" quiescence. Nightly
averaged preliminary magnitudes outside eclipses are below:
mid-UT mag S.D. N band
-----------------------------------
951118.618 13.27 0.075 904 V
951119.505 13.98 0.086 71 V
951120.534 15.55 0.130 91 V
951121.554 15.89 0.141 477 V
951122.494 15.93 0.210 303 V
(S.D.: for a single point)
The light curves on Nov. 21 and 22 show broad undulations with a time-
scale of few hours, together with short-term flickering and QPOs. Although
the averaged system brightness has changed little these two nights, the
shapes of eclipses have changed considerably; the system is now exhibiting
rather sharp ingresses and egresses which are usually observed in quiescence.
Regards,
