During the 1995 outburst of HT Cas (P=0.0736d), the eclipses lasted
slightly less than 10 min. Recommened protocol of visual estimates: a few
times per minute, to accuracy of seconds. Visual observers in the case
of HT Cas commented a tape recorder was quite useful. A story of dead tired
CCD observing is given at the URL:

Wishing for your successful observations!
