\n\tHere are predictions for the most favourably timed eclipses from the UK during November and December:<\/p>\n

<\/p>\n

\n\tTimes are in UT (same as GMT).<\/p>\n

\n\tRemember that these times are only approximate. Observed mid eclipse times can sometimes differ from predictions by half an hour or more.<\/p>\n

\n\tRZ Cassiopeiae<\/strong><\/u><\/p>\n

\n\tEclipses 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<\/p>\n

\n\tNov:   3d   20:40 ,  9d  20:05 ,  15d  19:35 ,  17d  00:10 ,  21d  19:00 ,  22d  23:40 ,  27d  18:25 ,  28d  23:05.<\/p>\n

\n\tDec:   3d  17:50 ,   4d  22:30 ,   9d  17:15 ,   10d  21:55 ,  16d  21:20 ,   22d  20:50 ,  28d  20:15 ,  30d  00:55.<\/p>\n

\n\tU Cephei<\/strong><\/u><\/p>\n

\n\tEclipses 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.<\/p>\n

\n\tUnfortunately, as can be seen below, primary eclipses during November and December will not be occurring at a convenient time of night.<\/p>\n

\n\tNov:   5d  03:10 ,   10d  02:50 ,  15d  02:30 ,  20d  02:10 ,  25d  01:50 ,  30d  01:30.<\/p>\n

\n\tDec:   5d  01:10 ,  10d  00:50 ,  15d  00:30 ,  20d  00:10 ,  24d  23:50 ,  29d  23:30.<\/p>\n

\n\tU Coronae Borealis<\/strong><\/u><\/p>\n

\n\tEclipses last for approx 12 hours. The times shown below are for the eclipse mid-point.<\/p>\n

\n\tWith Corona Borealis sinking towards the evening twilight and only rcently emerged from the morning twilight, opportunities for seeing U CrB in eclipse will be rather limitd.<\/p>\n

\n\tNov    29d  18:20<\/p>\n

\n\tDec     3d   05:10 ,  10d   02:55.<\/p>\n

\n\tbeta Lyrae<\/u><\/strong><\/p>\n

\n\tBoth the deeper primary eclipse and less deep secondary eclipse can be followed visually. There is no period of constant brightness between eclipses.<\/p>\n

\n\tPrimary:        Nov  6-7  ,  19-20  ,   Dec  2-3  ,  15-16  ,  28-29.<\/p>\n

\n\tSecondary:   Nov 12-13  ,  25-26  ,  Dec  8-9  ,  21-22.<\/p>\n

\n\tbeta Persei (<\/strong><\/u>Algol)<\/strong><\/u><\/p>\n

\n\tEclipses 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.<\/p>\n

\n\tNov  9d  00:45 , 11d  21:30 , 14d 18:20 <\/span><\/span><\/p>\n
