AAVSO Special Notice #221
Outburst of the infrequently outburst dwarf nova HT Cas
November 2, 2010
As reported by Tim Parson (Circle Pines, Minnesota, USA) and confirmed
by Pavol Dubovsky (Kolonica, Slovakia), the infrequently-outbursting
dwarf nova HT Cas is in outburst. Parson observed HT Cas in outburst at
m(vis)=12.9 on JD 2455502.93 (2010 November 2.43), and the outburst was
confirmed by Dubovsky at m(vis)=12.4 on JD 2455503.3 (2010 November
2.8). The last confirmed well-observed outburst of this star occurred
on 2008 January 10. Observations of this variable are strongly
encouraged at this time. Both visual and CCD observations are
encouraged, and CCD time-series data are particularly encouraged if
possible.
HT Cas is classified as a UGSU-type dwarf nova with eclipses, having an
orbital period of approximately 0.0736 days (106 minutes). We ask all
observers to contribute whatever observations they can throughout the
outburst. CCD observers are asked to perform time series observations
if possible, keeping the best balance between short integration times
and good signal to noise.
HT Cas is located at the following (J2000) coordinates:
RA: 01 10 12.96 , Dec: +60 04 36.3
Charts for HT Cas may be plotted using AAVSO VSP:

There is a m(vis)=13.9 comparison star approximately 30 arcseconds south
of this star, HT Cas is easily separated and the identification should
be clear.
Please promptly submit all observations to the AAVSO using the name "HT
CAS".
