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

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

<\/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\tJan:   3d   19:40 ,  5d  00:20 ,  9d  19:05 , 10d   23:45 , 15d  18:30,  16d   23:15 ,  21d  18:00 , <\/p>\n

\n\t        22d  22:40 ,  27d  17:25 ,  28d  22:05.<\/p>\n

\n\tFeb:  3d   21:30 ,   5d  02:10 ,  9d  20:55 ,  11d  01:40 , 15d  20:20 ,  17d  01:05 ,  21d  19:50 ,  <\/p>\n

\n\t        23d  00:40 ,  27d  19:15.<\/p>\n

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

\n\tEclipses last for approx 9 hours. Hence these eclipses will be underway by mid evening and will end in the early hours of the morning.<\/p>\n

\n\tThe 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\tJan:    3d  23:15 ,   8d  23:55 ,  13d  22:35 ,  18d  22:15 ,  23d  21:55 ,  28d  21:35.<\/p>\n

\n\tFeb:   2d  01:15 ,   7d  00:55 ,  12d  00:35 ,  17d  00:15 ,  22d  23:55 ,  27d  23:35.<\/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 not rising until after midnight, opportunities for seeing U CrB in eclipse will be rather limited.<\/p>\n

\n\tJan      3d   06:50 ,  10d  04:35 ,  17d  02:15 ,  24d  00:00  , 30d  21:40.<\/p>\n

\n\tFeb    10d   06:15 ,  17d  03:55 ,  24d  01:40.<\/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:        Jan   9-10  ,   22-23  ,              Feb   5-6  ,  18-19.<\/p>\n

\n\tSecondary:  Jan   3-4  ,  16-17  ,  29-30  ,   Feb  12-13  ,  25-26.<\/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\tJan   11d   02:35 ,  13d  23:25 ,  16d  20:15 ,  19d  17:05<\/p>\n
