Times are in UT (same as GMT)

RZ Cassiopeiae

Eclipses last 4.8h, with most of the brightness changes taking place during the middle 3 hours. The times shown below are for the mid-point of the eclipses

Jan:  27d 22.8h , 29d 3.5h.

Feb:  2d 22.2h, 4d 2.9h, 8d 21.7h, 10d 2.3h, 14d 21.1h, 16d 1.8h, 20d 20.5h, 22d 1.2h, 26d 19.9h, 28d 0.6h.

Mar:  3d 19.4h, 5d 0.1h, 10d 23.5h, 16d 22.9h, 18d 3.6h, 22d 22.4h, 24d 3.0h, 28d 21.8h, 30d 2.5h.

U Cephei

Eclipses last for approx 9 hours. The times shown below are for the eclipse mid-point. Eclipses are total, so there is a period of constant brightness around the middle of the eclipse.

Jan:  30d 21.8h.

Feb: 4d 21.4h, 9d 21.1h, 14d 20.8h, 19d 20.4h, 24d 20.1h, 29d 19.8h.

Mar:  5d 19.4h, 10d 19.1h, 15d 18.8h.

U Coronae Borealis

Eclipses last for approx 12 hours. The times shown below are for the eclipse mid-point.

Jan:  30d 23.2h.

Feb:  17d 5.5h, 24d 3.2h.

Mar:  2d 0.9h, 8d 22.6h, 15d 20.3h, 22d 18.0h.

beta Lyrae

Both the deeper primary eclipse and less deep secondary eclipse can be followed visually. There is no period of constant brightness between eclipses.

Primary:  Jan 26-28 ,  Feb 8-10 , 21-23 ,  Mar 5-7 , 18-20.

Secondary: Feb 2-3 , 15-16 , Feb 27-28 ,  Mar 11-12 , 24-25.

beta Persei (Algol)

Eclipses last for approx 10 hours. The times shown below are for the eclipse mid-point. Eclipses are total, so there is a period of constant brightness around the middle of the eclipse.

Feb:  2d 0.7h, 4d 21.5h, 7d 18.3h, 22d 2.4h, 24d 23.2h, 27d 20.0h.

Mar:  16d 0.9h, 18d 21.7h, 21d 18.6h.
