Society News

Night Scenes 2014We have ordered 20 copies of Night Scenes 2015. Compiled by Paul Money, who will hopefully be coming up to speak in spring 2015. All who purchase NSC will know it to be an indispensable colour almanac/ booklet, packed full of information on the coming year’s monthly celestial highlights. The price will be £4 to paid up members, £6 for non members. First come, first serve as usual.

It was a very encouraging turnout for our first meeting of the ‘new season’, and a new format as well. Apart from usual society news and business and a review of the night sky using Sky pro plus 7, each monthly meeting will also feature ‘mini’ presentations on a particular item relating to astronomical news and events, or a more in depth look at a particular celestial object, theory, or topic.

Last month Andi gave a brief, but very interesting presentation on NASA's Grail Mission, and its discovery of a huge rift valley on the moon.

Talk - "First Encounter"In this month's meeting:

Mark will talk about initial results from the fly-by of comet Siding Spring's pass of Mars.

Talk - "Blind date with a comet"Andi will also be giving a small presentation about the Rosetta mission, in particular the lander "Philae", which hopefully will make it safely to the comet surface on 12th November.

We do hope you can come along, it’s not only good to see more faces, but also the society functions more effectively as well.

Sky Notes

In this month's Sky Notes:

Planetary Skylights

There is little notable planetary action in the evening sky during November. Mars continues in its race to outrun the Sun and the horizon, lingering just above the SW horizon for an hour after sunset. On the 25th & 26th it is joined by a crescent moon. toward the SW horizon.

Looking South: Jupiter at 06:00h

By mid month conspicuous Jupiter is rising before midnight and is on view by 10pm at the month’s end across in the east. However as far as practical telescopic observations are concerned it really should still be classed as a morning object. By dawn it rides high to the SSW and is unmistakable, residing just ahead of Regulus and the ‘sickle’ in Leo. The Moon lies nearby on the 14th and 15th.

Looking East: Mercury
06:00h on 30th October 2014

The planetary highlight of the month will be the continued morning apparition of the innermost planet; elusive Mercury. Look for it across in the ESE from the 1st until 20th around 45 mins before sunrise. Mercury will be highest at the start of November; a very respectable 10 degrees above the horizon and after a little searching should become readily apparent to the naked eye. As the month progresses Mercury will drop back toward the horizon getting brighter as it does so. Perhaps the optimum dates will be 12th to the 15th. Use binoculars if you cannot initially spot it.

Looking South-West: Uranus
& Neptune 20:00h on Nov-08

Uranus came to opposition early last month and is now well placed for observation during the evening. See chart. Neptune is visible in a telescope and lies near Sigma Aquarii.

Meteor Activity

Look out for the Leonids and Taurids during November:

  • The Leonids are active from Nov 15-20 and will peak this year during the very late evening of Nov 17, which means the early morning of the 18th will be the optimum time to view. ZHR’s are expected to be normal, ie around 20 per hour, so an observer may expect to view around 7-12. The Leonids are usually a quiet shower but are famous for their outbursts. These meteor storms are expected roughly every 33 years (the orbital period of the showers parent comet - Temple Tuttle) The next one is not expected until 2030 at the earliest.
  • Keep an eye out for a few meteors on the night of Nov 4/5th when the South Taurid meteor shower reaches a peak, and then again on the night of Nov 11/12 when the North Taurid meteor shower peaks. This is a very long duration shower with a low rate of about 5 meteors per hour. The peak does not increase much from this, but both Taurid showers span over a month. Taurids may well be few, but they are very bright with bright fireballs and therefore well worth keeping an eye out for.
  • The Taurids are an old shower, associated with Comet Enke, which has a period of just 3.3 yrs. Over time dust from this comet has been depleted and spread out over a broad swathe of the inner solar system, giving rise to Taurid meteor showers not only on Earth but also on Mars and Venus too!

Comet C/2013A1 Siding Spring Passes Mars

voyage into the inner solar system

Passing Mars at a distance of just 87 thousand miles, comet Siding Spring became the first comet from the Oort cloud to be studied up close, thanks to a battery of orbiters and landers in-situ at Mars. (Although most were parked out of harm’s way - just in case) The close passage of the comet on Oct 19th could even be followed live on the web. Mark will be giving a brief synopsis of events at the Nov meet. And so as one close encounter involving a comet becomes yesterday’s news, so another close encounter involving a comet will, if all goes to plan, become big news shortly.  

The Rosetta Mission - Philae has landed!

67P//Churyumov-Gerasimenko

Well, not yet, but we hope everything goes according to plan for possibly the highlight of the year for space related matters.

After its 10 yr journey, ESA’S Rosetta spacecraft finally rendez-vous-ed with comet 67P/ Churyumov - Gerasimenko on Aug 6th with the historic first landing of a probe on a comet scheduled to go ahead on Nov 12th. Touchdown will hopefully be around 4pm UK time, so keep tabs across the media.

Andi will be giving a presentation on the Rosetta mission at the Nov meeting. Update:- Please go to homepage - The day mankind landed on a comet.

In the News

In mid-September WDAS Members hoped to see a display of the Northern Lights after a solar flare rated X1.6.  But in April, NASA's 'Swift' Satellite witnessed a solar flare emitted from a young Red Dwarf star, estimated at X100,000.  Could our sun do that?  What would happen to an 'earth' orbiting that star? ...

First Image of Comet Siding
Spring at closest point to Mars

Comet season is Open!  Not only is the Rosetta Satellite orbiting a comet on which it hopes to successfully deposit a lander next month, but we'll have a chance to observe Comet Siding Spring at close quarters on Sunday 19th October.

For a couple of reasons, Comet Siding Spring is providing us with a rare treat...

NASA’s Hubble Space Telescope has produced a unique composite image of comet Siding Spring as it made its never-before-seen close passage of a comet by Mars.

Here's what we know so far...
