The Star Stories astronomy programme at Abriachan Forest is going from strength to strength, with tickets selling out far in advance of each event.  Since the last update we’ve hosted two stargazing evenings, involving guest speakers Dr Anthony Luke (UHI) and Professor Martin Hendry (Glasgow University).

The November event was a Leonids special, held near the peak of the annual meteor shower on Nov 16th, with the promise of perhaps observing some early atmosphere skipping Leonids.

Dr Anthony Luke presented a fascinating set of lectures on the chemistry of meteors and stars in the forest classroom, touching on the incredible pressure and heat generated within stellar forges that produce all the elements we see around us.

Meanwhile, I led the stargazing component outside with perfectly clear skies allowing us to take in the brightest stars, and views of the gibbous Moon in video telescope.  The lunar observing was particularly captivating, and we discussed the formation of the lunar maria and highlands, and the Theia Moon formation hypothesis.

Clelland was also in action over the forest campfire making wooden star models for the younger participants.  There were no dramatic meteor sightings to match October’s spectacle but the event certainly whetted everyone’s appetite.

 

Then on December 5th, Glasgow University’s Professor Martin Hendry (of gravitational wave fame) joined us under dark skies for a Wednesday night special.

Martin is a hard working and inspirational advocate of all things astronomy and space.  Prior to me collecting him at his hotel he had already delivered a packed day of outreach to Inverness schools and hadn’t had a bite to eat since lunch.  Despite this he was incredibly grateful for the cold pizza I offered him on our drive out to Abriachan, and this meagre fare fuelled him sufficiently to deliver two fantastic talks on dark matter and gravitational waves in the forest classroom.  His talk highlighted some of the latest discoveries and simulations from the LIGO (Laser Interferometer Gravitational-Wave Observatory) team.

The following day he was off on the train again to speak to more schools in the far north.

We were also blessed with lots of clear breaks on the 5th, so I once again led the observing component outdoors, this time taking groups further back into the darker areas above the classroom where the Milky Way was ablaze, and fainter fuzzies like the Andromeda galaxy leapt out at us in our binocular and naked eye views.  Amongst many things we discussed the evolution of hot massive stars like Betelgeuse and the Kepler exoplanet survey, which has been scanning vast numbers of star systems close to Cygnus and Vega, cataloging extrasolar planets.

Prior to packing away the binoculars I snapped some pictures of the starry skies close to the forest classroom (attached).

Both evenings have garnered fantastic feedback and we’re looking forward to the next events, listed below.

As always a big thanks to learning coordinator Suzann Barr, Ronnie, Clelland and the rest of the Abriachan team who help make these events so welcoming and successful.  We’re also grateful to grant funding from the STFC, allowing us to invest in observing equipment, free transport and to extend the scope of this year’s programme.

Future Star Stories Events

Winter Solstice Special (21st December 2018) – Solstice talk and Moon observing with astronomer Stephen Mackintosh, turn of the year campfire twists with Clelland.

Stargazing with Dark Sky Man Steve Owens (12th Jan 2019) – Stargazing with author of Stargazing for Dummies Steve Owens

Star Stories Photography Special with guest Graham Bradshaw (9th Feb 2019) – Local landscape, aurora and night sky photographer Graham Bradshaw shares his stories of nights spent on exposed hillsides and offers tips to budding photographers.

The Geminids 2018

The Geminids, one of the most reliable and active meteor showers of the year is upon us with peak activity predicted between Dec 13th – Dec 14th.  Under the very best possible observing conditions the Geminids have been known to produce displays of up to 100 meteors per hour, although you’ll likely see rates much lower than this.

Occasionally and unpredictably, meteor showers can erupt into storms. One of the most famous happened in 1833 when the Leonids produced over 100,000 meteors per hour! Who knows what this December’s Geminids will bring?

Observing the Geminids

You don’t need any special equipment to view a meteor shower, in fact binoculars or telescopes will just narrow your field of view. Grab a deck chair or a warm blanket, prepare a hot drink, wrap up warm and lay out under the darkest conditions you can find. It’s an excellent activity to do alone or if you have children they’ll love an excuse to get outside for some after dark play.

Put away any lights or bright mobile phones and simply look up and wait. Remember it takes up to 30 minutes for your eyes to fully dark adapt and any exposure to bright lights will start the process all over again. If you need a light red touches are best for preserving you night vision.

For optimal viewing, head out late at night after the Moon sets or in the darkness of the pre dawn sky., when the Gemini radiant is highest in the sky

Good luck and clear skies!

Comet Hunting – 46P/Wirtanen

This month brings the excitement of a comet hunt, as Wirtanen 46P reaches closest approach on December 16th.  This is a relatively small comet (1.5km across) with a period of just over 5 years.  However Wirtanen is known to produce a relatively large tail for its stature, so it’s definitely one to look out for.  In mid December it’ll be positioned between the Pleiades star cluster and red giant star Aldebaran in Taurus, so will be relatively easy to locate in the night sky.

Reports of naked eye sightings and some photographs are already emerging online despite the current low altitude of the comet at high norther latitudes.  However its vantage will steadily improve as we head into mid December, although Moon conditions will become less favourable then, so time your hunt well.

Wirtanen should be observable in a wide-field telescope or binocular view, and possibly naked eye under very dark conditions.  You could also try locating it by taking a 10-30 second exposure in your DSLR camera.

I’ve put together a short video to help you locate it over December.   Clear skies!

Venus Morning Star

The planet Venus is a brilliant morning star at the moment. Catch it rising in the south east ahead of the Sun between 5.30am and 7.30am.

With keen eyesight and binoculars you should be able to discern Venus’s phase, currently a beautiful crescent. A telescope will make this much clearer as demonstrated by this video footage I shot last year, when Venus was ‘the evening star’.

Over the month of November Venus will get brighter as its phase waxes from a thin crescent to a 25% illuminated disc at month end.  Despite this brightening Venus is actually travelling away from us and after December 2nd its brightness will begin to diminish as it pulls further away from earth and its disc size shrinks .

Once Venus passes behind the Sun it will eventually reappear as an evening star around mid August 2019.

Clear skies!

Meteoric Start to New Star Stories

The new Star Stories astronomy programme for the 2018/2019 season got off to a great start up at Abriachan Forest Trust last Friday, with plenty of clear breaks in skies for Milky Way observing and binocular stargazing. This was despite very unsettled weather predicted by the MET office as storm Callum blew in from the west.

This first event was in collaboration with the Highland Archaeology Festival, and pitched on a loose Neolithic stargazing theme which I had worked into a backup talk in the event of cloudy skies.  As it happened we had enough clear conditions to stargaze all evening and the talk was parked for another occasion.

Due to the healthy turnout we split the night into two streams, with one group joining Abriachan’s Clelland for Celtic tales around an open fire, while the other group joined me under darkness for a laser pointer and binocular tour of visible constellations.  We then swapped over at half time.

Both stargazing groups saw plenty of open sky despite fast moving cloud, and we were able to field test the new hand held binoculars funded by our STFC grant.  The Milky Way and summer triangle were on fine display in the south with bright lanes of glowing star fields high overhead.  We also saw most of the northern circumpolar constellations, including Ursa Major, and discussed Polaris at some length before sighting the Pleiades in the East and the rich clusters within Perseus and Cassiopeia.

But the most dramatic event was gifted to the first group of stargazers, when a spectacular burning meteor soared overhead towards the north, briefly lighting up the whole sky.  A subsequent discussion on social media prompted another observer in Lairg – Chris Cogan – to post a picture of a very bright meteor he also saw streaking north and lighting up an entire hillside.

This generated a lively discussion and some investigation into how far away two observers can be situated and still see the same bright meteor.  It turns out pretty far!

Due to the high altitude meteors burn up in the atmosphere, about 40 – 60 miles overhead, it’s very possible for two observers hundreds of miles apart to see the same meteor.  The only requirement is they lie along the same approximate vector as the burning space rock.  In this specific case, Abriachan and Lairg are both in a rough line travelling north.  The time recorded on Chris’s picture also checks out with our observing time at Abriachan.  So, all told, reasonably convincing evidence we witnessed the same fireball, seventy miles apart.

Overall feedback on the night has been great so far and I’m already looking forward to the Leonids Special in November, when we will be joined by guest speaker Dr Anthony Luke of UHI, talking about the chemistry of stars and meteors.

Clear skies!

STFC Support for Astronomy Outreach

24900062_1994723217431287_4261072682509033538_n

I received some fantastic news this week. The Science and Technology Facilities Council (STFC) are supporting our continued programme of astronomy outreach at Abriachan Forest Trust, via a SPARK award.  The news was published in the BBC Highlands & Islands website here.

STFC council members were impressed with the successful pilot events delivered over the winter, bringing together astronomy, science and culture through the medium of stargazing and storytelling.

The released funds will be invested in observing equipment, landscape astronomy props, and transportation costs to help families without vehicles access future events.  They will also help us deliver another 12 events out at Abriachan over the next year and into 2019.

I’d like to personally thank the following individuals for their formal letters of support on the bid:

Suzann Barr – Learning Coordinator at Abriachan Forest Trust

Martin Hendry – Professor of Gravitational Astrophysics & Cosmology and Head of the School of Physics & Astronomy, University of Glasgow

Steve Owens – Dark Sky Consultant and Author of Stargazing for Dummies.

Elizabeth Barron-Majerik – Project Development Manager, School of Forestry, Science, Maths and Aquaculture, UHI

But most of all thanks to everyone who have attended the Abriachan stargazing sessions so far, during clear and wild weather.   Keep a look out for the future list of events.
