Manastro Journal for December

With the country still in lockdown, unfortunately Godlee Observatory is closed for the forseeable future. Why not join us instead for a 'Zoom' webchat, most Thursday evenings. See Facebook for details.

A Special mention must go to Kevin Kilburn, who last month celebrated 50 years as a Member of the Society. He was "virtually" presented with a crystal representation of the Godlee Observatory and the telescopes therein.

Congratulations Kevin.

Planet(s) of the month: Saturn & Jupiter

We are graced with a rather special occurance this month, with Jupiter & Saturn making their closest conjunction of 6.1 arcminutes separation since 1623!

On the evening of 21st December, the two planets will appear very low in the southern sky - about 14° elevation at sunset (4pm), this will reduce to 10° by about 5pm, so a good low view of the South is essential. 

Naked eye the two will appear as a single bright object (mag -1.8), but with a pair of binoculars, or a telescope you should be able to see the two planets easily within the same eyepiece view.

Th two planets wont be this close again until 2080, so dont miss it (Manchester weather permitting of course!)

Constellation of the Month: Orion (shown 15th December 22:00)

Orion

Orion constellation is one of the brightest and best known constellations in the night sky. It lies on the celestial equator.

Orion has been known since ancient times. The constellation is also known as the Hunter, as it is associated with one in Greek mythology. It represents the mythical hunter Orion, who is often depicted in star maps as either facing the charge of Taurus, the bull, pursuing the Pleiades sisters, represented by the famous open cluster, or chasing after the hare (constellation Lepus) with his two hunting dogs, represented by the nearby constellations Canis Major and Canis Minor.

The constellation Orion contains two of the ten brightest stars in the sky – Rigel (Beta Orionis) and Betelgeuse (Alpha Orionis) – a number of famous nebulae – the Orion Nebula (Messier 42), De Mairan’s Nebula (Messier 43) and the Horsehead Nebula, among others – the well-known Trapezium Cluster, and one of the most prominent asterisms in the night sky – Orion’s Belt.

Orion is the 26th constellation in size, occupying an area of 594 square degrees. It is located in the first quadrant of the northern hemisphere (NQ1) and can be seen at latitudes between +85° and -75°. The neighboring constellations are Eridanus, Gemini, Lepus, Monoceros and Taurus.
