Two Eclipses in November.

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.
