New web presence for the CIAS
The Cayman Islands Astronomical Society is now publishing regular updates on our facebook page.
Cayman Astronomy this weekend 5th August and 7th August
The Cayman Islands Astronomical Society will be at The Marriott Hotel again this Friday night 5th August for a promotional “Dark Night” evening. (weather permitting) .
The
evening starts around 7:30 PM. We are located close to the beach on the Southern side of the complex- near the “Jacuzzi”
The Society also has its regular monthly meeting on Sunday 7th August at St Pedros Castle – starting 7 PM
All welcome to both events – phone Richard for more details 925 4917 . Member of the General Public are welcome
But please park outside and walk in. In the event of being more than 50 percent cloud the meeting is cancelled.
We have 5 visible planets in the sky at the moment
– these should be visible form both our venues this weekend. The Pedros
Meeting will however allow us to see the famous “Teapot” Asterism- and
within the “steam” from the spout -the Centre
of our Milky Way Galaxy.
This month also brings us the Perseid meteor shower which always brings huge interest from the Press.I don’t want to discourage people but here in
Cayman our latitude means we don’t quite get the full effect of more
Northern Latitudes.
The figure normally quoted is an estimated Maximum
figure assuming excellent visibility and No Moon with the Radiant- he
portion of sky where the meteors appear to radiate form (from the
Constellation of Perseus) directly overhead. This
year its predicted to be 300 meteors per hour between Aug 11 and the 13th
. Its also best to see the shower AFTER midnight – 2AM for example is a
good time- as the Moon which is almost full sets at 1 AM on the 12th . Good Luck!
Next Meeting 8th June at St Pedros 7:30 PM
You can met up with us next at St Pedros on Wednesday 8th June starting 7:30 PM. Visitors are asked to park outside and walk in.
If the sky is more than 50 percent cloudy the meeting will be cancelled
phone not text if in doubt - number is below

April Newsletter
The next General Public
meeting is on Sunday 10th April
at St Pedros Savannah. Richard McLeod will be
hosting the evening – starting 7 PM onwards. Usual rules apply if the
weather is more than 50 percent cloudy the evening will be cancelled. You can
phone Richard on 9254917...
On Monday May 9th next Month is the Transit Of Mercury - where the planet Mercury will slowly cross the Suns disk - to see the event we recommend coming to see the Astronomy Society and the UCCI observe the event safely at the UCCI Observatory. If you would like to come please email cayman.astronomy@yahoo.com

Other Events coming up soon
Feb 27th Red Sky at Night (4th year
on Astronomical Avenue)
March 10th
Meeting at Pedro’s with Savannah Primary School.
March/April
Campaign to start Astronomy
Societies in Schools and Clubs in Sister Islands
Volunteers will be needed to help manage
both the Red Sky at Night evening (free tickets will be provided) and also for
the evening for Savannah Primary School.
Members have precedence
The
Morning Skies in February are very much the realm
of the planets. Currently all 5 planets visible with the naked eye can be seen.
Although as one smart alec has pointed out – the Earth is also visible too. The diagram shown below is a reasonable
example of what can be seen – although in Cayman the line of the planets is
much higher in the sky – almost overhead. . Notice Mercury and Venus- as the
month progresses Venus will get closer to Mercury – but the best date to catch
them is probably Feb 6th when a slim crescent moon will sit between
the two planets.
It’s going to be interesting to watch the
motion of the planets across the sky this year.
Firstly we have all the visible planets in one place! The last time this
happened was in 2005 over 10 years ago. We are indeed lucky with Mercury as
it’s normally very elusive but it will be visible for quite a while slipping
back into the dawn at the end of March.
Mercury will reappear as an evening object in April – and again does
another “dance or loop” in the sky
before returning sunwards in May when on
May the 8th the planet orbit
is so aligned we will be able to see the disk of the planet crossing the Sun, -
a type of eclipse called a Transit. More in this in later newsletters.
Venus
meanwhile in February does not – at our latitudes -completely go away- it
remains low in the morning sky – simply put it is at its furthest from the
Earth and appears to crawl in its path around the Sun. Simply put its
approaching its “Superior Conjunction”. See the diagram below. In June Venus eventually
appears in the evening. By the end of
the year Venus will be a brilliant Evening Sta
As we turn our gaze towards the outer
planets – Mars, Jupiter and Saturn, all will be visible in our Summer evening
skies, special mention to be mad of Mars as it will be the closest to the Earth
(at its Opposition) since 2014 . It will
be even bigger and brighter in 2018!
Evening
Skies February
Now we turn to the evening sky. Sunset on
the 11th is around 6:20 PM – the chart below is for 8:30PM and is
taken from the excellent site Heavens-Above.com. The time shown is later than
normally used in the newsletter but I wanted to show that at long last Jupiter
is coming back to the evening skies. Certainly I am hoping we will catch it at
the Red Sky at Night Event.
Heavens-Above.com is a great site for
satellite predictions too- there will be some crossings of the International
Space Station towards the end of the Month (around the 20th) which I
will post up on the Facebook page.
Finally I have always been intrigued at
just how far we can see into the “Southern Skies”- The Southern Cross for
example has been visible recently in our Morning Skies – and in April/May/June
we get a great viewing of it again in the Evening. One Southern Sky object that
has eluded me however is just a bit too close to the horizon for us to see
clearly. This is the object LMC, the Large Magellanic Cloud. I know our astronomical friends in Trinidad
can see this Ok but here… a bit of a challenge.
The LMC is a familiar sight to Southern Hemisphere observers- and looks
like a small part of the Milky Way that’s slipped away. It is in fact a
satellite galaxy to our own Milky Way.
In
theory we should just see it – as the
center of the object is 20 degrees south, on our chart (above) it lies just
south of Dorado (The dolphin) The line to draw is from Sirius and pass to the
right side of Canopus. Canopus on the chart is the bright un named star in the
South. The other rule is that when Orion
is at its highest in the sky – so is the LMC
Let’s Hope for Clear Skies Everyone!! Don’t forget our Website and Facebook page
too.
