Here are predictions for eclipses that are reasonably favourable from the UK during April and May:
Times are in UT (same as GMT, 1 hour behind BST - so, for example, 20.6h UT is 21.6h BST)
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
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.
May: 7d 3.2h , 12d 2.9h , 17d 2.6h , 22d 2.3h , 27d 2.0h.
U Coronae Borealis
Eclipses last for approx 12 hours. The times shown below are for the eclipse mid-point.
Apr: 2d 2.7h , 9d 0.3h , 15d 22.0h , 22d 19.7h.
May: 10d 2.0h , 16d 23.7h , 23d 21.4h , 30d 19.1h.
Both the deeper primary eclipse and less deep secondary eclipse can be followed visually. There is no period of constant brightness between eclipses.
Primary: Apr 13-15 , 26-28 , May 8-10 , 21-23.
Secondary: Apr 7-8 , 20-21 , May 2-3 , 15-16 , 28-29.
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.
