For observers in the UK, the 14th of November will be an opportunity to observe two eclipsing variable stars in one night. RZ Cassiopeiae will be in mid-eclipse at approximately 22:00 UT; as will Beta Persei.
The duration of RZ Cassiopeiae’s eclipse is approximately five hours and the duration of Beta Persei’s eclipse is nine and a half hours. You can start observing these stars as soon as it gets dark; using the charts on the SPA’s website. Try and make estimates every half-hour and report any observations you make to the SPA VSS.
