Whitby & District Astronomical Society

Continuing the tour of stellar objects crossing the meridian line this month: a double-star in the 'Sickle' of Leo, a field barred spiral galaxy also in Leo, knwon to its friends as "NGC 2903"; and the 'Ghost of Jupiter' planetary nebula in Hydra.

• Star: Algieba: the ‘The Lion's Mane’.
• Galaxy: NGC 2903.  Discovered by William Herschel in 1784, this barred spiral galaxy lies in Leo near the top of the lion's head, to the right of the sickle asterism
• Nebula: NGC 3242 - ‘Ghost of Jupiter’ nebula.

Following recent further correspondence with Dr Sean Paling regarding a visit to DMF at Boulby, it has been established that Friday’s are difficult for Sean and his team.  We're discussing other dates...

Together with other events at Dalby Forrest and Sutton bank, this was part of the NY National park’s dark sky awareness programme.  February is always a tricky month weather wise, it could be anything, so it came as a relief that Saturday 17^th proved to be a pretty quiet, clear day, a little chilly, but you expect that.

This was a last minute event – organised by the youth hostel.  Conditions on the evening were actually very good with clear skies and little wind.  Initially we thought hardly anyone was going to turn up, but by 18:30h a sizeable gathering had mustered on the front quadrangle in front of the Abbey Visitor centre...

The start of April offers up an interesting stellar challenge, testing the observing dexterity of astronomers; casual or otherwise in a race against time..  This is all about spotting first magnitude stars; those ranked brightest in the sky.

Piercing the spring twilight dotted around the sky, no less than thirteen of these are currently visible, more than at any other time of year.  However the window of opportunity in which to identify these stellar jewels rapidly diminishes as we head deeper into April...

The date of the Vernal Equinox and officially the start spring in the northern hemisphere falls on March 20th this year.  This is when the Sun's path - the ecliptic, first crosses the celestial equator on its apparent journey northwards into the sky.  The orientation of the Earth at the spring or autumnal equinox is such that neither of the poles are inclined towards the Sun and all locations experience equal hours of daylight and darkness - hence the term equinox...

In this month's edition:

• Planetary Skylights: Venus, Mercury, Jupiter, Mars, Saturn and two Lunar Occultations
• Meteors: perhaps some Viginids
• March 2018 Sky Charts

As part of the Dark Skies festival held throughout February half term across North Yorkshire and beyond, our society will be hosting a ‘star party’ at the Danby Moors Centre.  And the RAF Fylingdales event planned for January 18^th, and organised by York A.S, the base, with assistance from us, had to be cancelled, victim of the wintry conditions...

In this month's edition:

Our Christmas meal at the Hare and Hounds once again proved a great success with ten members making it to the banqueting table.  The food was excellent, the wine flowed (favouring certain parts of the table more than others) and the company, most convivial.  Crackers, crackers...

Continuing our new feature, we take a brief look at this month’s selection of objects of particular interest crossing the meridian line.

• Star: 119 Tauri (CE Tau) – The Ruby star in the constellation Taurus.
• Cluster: The 37 cluster – it would have been very easy to go for the Pleiades, however I'd like to highlight an object you may not have heard of, yet it certainly deserves scrutiny.
• Nebula: The nebula Messier 78 (or NGC 2068) is a reflection nebula in the constellation Orion.

In this month's edition:

• Planetary Skylights: Jupiter, Mars, Mercury and Saturn
• Earth Reaches Perihelion
• Supermoon and Blue Moon
• Meteors: Geminids, Ursids
• January 2018 Sky Charts

Starting this month is a new feature in which we take a brief look at various celestial objects of particular interest for one reason or another.  These are a star, a galaxy, a nebula and a cluster.  To keep matters simple all the objects are located on or close to the meridian line, due south, around mid month at 20:00h ( GMT time).  The objects are ranked as Easy, Medium or a Challenge to observe with the type of optical aid required to spot them...
