Christmas & New Year Skies

December & January Night Skies in 2017/2018

The Headlines:

  • This year in December we will be treated to a favourable Geminds Meteor shower
  • Saturn is disappearing from view,
  • Jupiter and Mars begin their close encounter in the morning skies.
  • We get a good look at the constellations Perseus, Pegasus & Andromeda in the northern sky.
  • The “Ghoul Star” Algol, a star that we can observe changing colour and brightness over just 10 hours is in prime viewing!
  • In January its all about the Moon, We start the month with a Super moon and end it with a total Lunar eclipse
  • Mars and Saturn are at their closest in the early morning in the 1st week of January

Geminids Meteor Shower

The Geminids are one of the most prolific meteor showers of the year with up to 120 Meteors per hour gracing our skies, in a display that peaks on the 14th of December. The shower is active between the 4th and 17th of December. Unlike last year, the Geminids this year coincide with the New Moon giving the opportunity to see the maximum number of Meteors against the dark moonless sky. To see the Geminids, look to the NE from around 9 to 10pm and you may see some rising from the horizon, but they peak in the Northern sky at their highest altitude around 2am, with no moon to interfere.

Mars, Jupiter, Saturn & others

The King of the Planets Saturn is lost in the solar glare over December and January, however Jupiter and Mars will have a close pairing that starts on the 31st of December culminating on the 7th of January at just 0.3 deg separation before drifting apart again. For those keen to seek them out, Neptune and Uranus are visible in the evening skies, but you had better bring a telescope as they are just at or below naked eye visibility.

Perseus, Pegasus, Andromeda & the Demon Star

Early evening in December see’s the constellations Pegasus, Andromeda & Perseus dominating the Northern sky. These constellations are notonly the scene for ancient tales of Heroes, Monsters and maidens in distress. They are the home of 2 Galaxies that can be seen with binoculars or even the naked eye (Triangulum & Andromeda Galaxies)

It is also the home of the bright star Algol or Beta Perseus from the Arabic “Head of the Ghoul”, this star was endowed with a tag of being “Evil” as the ancients could not explain its habit of changing in brightness and colour over a short 10 hour period. We now know that it is an  eclipsing binary pair with the fainter orange dwarf eclipsing the hot blue primary star every 2.9 days.

Super moon, Total Lunar Eclipse & Blue Moon !

January is dominated by the apparitions of The Moon.The month starts with a so called “Supermoon” on the 2nd of January, this is where the full moon coincides with the moon at Perigee (closest to earth). At this time the moon can appear to be 14% bigger and 10% brighter than the smallest (Apogee) full moon. Then at the end of the month the moon makes its Blue Moon Appearance (2nd full moon in 1 calendar month) with a Total Lunar eclipse, the eclipse begins at 9:45pm with totality beginning at 9 minutes to midnight and ending at 7 minutes past midnight. A total lunar eclipse is an event worth seeing with the moon going blood red to black as it passes into the earths deep (umbral) shadow.
