January 2001


There is no meeting scheduled for this month.
The society would like to launch a new edition of the planisphere in May this year. We would much appreciate if members of the society could find sponsors to help finance the project. For more information please contact:

The sky this month:

On the 25th, the moon will be at its most distant point from the Earth. Unfortunately the moon will then be only 4% illuminated. Mercury is back in the evening sky in the constellation of Capricornus. The moon is visible close to the planet Mercury above the western horizon on the 26th just after sunset. The planet will be at its furthest, 18o, from the setting Sun (greatest elongation east) on the 28th of January. On the night of the 2nd and 3rd of February, the moon is close to Jupiter and Saturn respectively, and on the 8th, we have the largest full moon of the year. The smallest full moon will occur on 02nd September. It is quite interesting to make photos of the moon on these two dates for comparison. The Alpha Centaurids meteor shower is active from the 28th January to 21st February. The peak activity being on the night of the 07th. With the nearly full moon, best conditions for observing will be in early morning just after moonset and before sunrise i.e. in early morning. You might have a better show on the early morning of the 6th when the moon sets earlier. The radiant of the shower is close to the brighter of the two pointer stars (alpha Centauri) following to the east of the southern cross.
