Thanks to all who stepped forward to help put at The Marriot
last week especially our newest member Janet Rush, the bad news is she is a
migratory visitor to the Islands and not back until April.
Meanwhile recently in Jamaica I was lucky enough to meet up
with Errol and Martin Rickman of the Jamaican Astronomical Association of
Jamaica – this Compass article appeared as a result of the meeting. http://www.compasscayman.com/caycompass/2015/11/27/Jamaican-stargazers-to-help-Cayman-students-see-in-the-dark/.
We were given a number of small telescopes which will be used to get our local
schools to be inspired enough to start their own Astronomy Society. I intend to
have a meeting in the New Year on how we do this, what schools should be
involved etc. Ideally we want the schools to approach us as these schools have
the best chance to do this. . We know already the schools that have done that –
and better it’s a mixture of private and Government Schools – but it does
bother me some schools appear to have no interest in Astronomy at all .
So lets move on to Decembers Skies.
Firstly
there’s a comet in the morning sky – and as its Christmas its one of the
candidates for the Star of Bethlehem of course. Comet Catalina seems to have two tails and to find it look at the chart to the left. Two mornings in particular will help you find the comet, On Dec 8 th the Moon and Venus will
form a triangle, but on January 1st the comet will be very close to
the star Arcturus! As I type this
newsletter the comet is only magnitude 5.5. As we know comets are notoriously
fickle and mostly end as a damp squib. However sometimes they are utterly
stunning. Fingers crossed.
December also brings a rare event in the afternoon of December the 7th when the planet Venus will disappear behind the disk of a slim 1 percent illuminated phase of the Moon –In Cayman (see chart below) the Start is 12:40 and a reappear 14:40 PM. Its not very well known but it is possible – with the right pointers - to see planets during the day time. So this event should be possible to see with binoculars BUT Please keep your vision well away from the Sun!
It will also be worth
catching Venus and the Moon in the early morning sky on that day too.
The New Moon is on the 11th so the meeting to be confirmed will be around the 13th
which is lucky because this year is particularly good for the Geminid meteor
shower with a maximum on December 13th to the 14th. There’s
no moon to interfere with the peak hour (just after midnight) and a maximum of
120 per hour is predicted this year.
The
following star chart for Grand Cayman is for the evening of the 13th
at around 8 PM. In the West Cygnus is now setting – The Great Square of Pegasus
is almost overhead and Orion and the two twins (Gemini) are in the East. Planet wise Jupiter is rising late in the evening.
It will be possible to get a glimpse of Mercury right at the end of the Month
just after sunset. Again take care with binoculars
December the 22nd is the Winter Solstice and a
day length of 10 hours 58m – not bad at all
So that leaves me to say a Happy Christmas and a Prosperous
New Year- one I feel will have lots of changes for me at least.
