Here are predictions for eclipses that are reasonably favourable from the UK during November and December:
Times are in UT (same as GMT)
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 primary eclipses. Eclipses are not quite total, so there is no spell of constant brightness at mid eclipse.
Eclipses of U Cephei, though still occurring well into the night, gradually become better placed for observers in the UK. By mid-December, mid eclipse is occurring near midnight and so the fade into eclipse will be observable from mid evening onwards.
Eclipses last for approx 9 hours. The times shown below are for the primary eclipse mid-point. Eclipses are total, so there is a period of constant brightness around the middle of the eclipse.
U Coronae Borealis
Corona Borealis is now only briefly visible at the start of the evening. It is, however, becoming increasingly visible in the pre-dawn sky. Both intervals of observability are, of course, far too short for the whole eclipse to be observable in one session, but parts of the fade/brightening will still be observable..
Eclipses last for approx 12 hours. The times shown below are for the primary eclipse mid-point. Eclipses are not total, so there is no spell of constant brightness around the middle of the eclipse.
Beta Lyrae is best placed for observation in the evening sky for most of this period, but by the end of the year is better placed in the pre-dawn sky.
Both the deeper primary eclipse and the less deep secondary eclipse can be followed visually. There is no period of constant brightness between eclipses.
Beta Persei (Algol)
Algol is well placed for observation for most of the night.
Eclipses last for approx 10 hours. The times shown below are for the primary eclipse mid-point. Eclipses are only partial, so there is no period of constant brightness around the middle of the eclipse.
