HT Cas has just entered outburst – it may be a superoutburst.  Good opportunity to have a go at time series.  HT Cas is an eclipsing UGSU star, so your light curve through an orbital period or two will look quite spectacular.  There is an eclipse ephemeris on my web page ( It’s quite old and needs a tweak, but it will give you a good idea as to when to expect minimum.

Good luck,
