International Dark Sky Week 20-26 April

April 20, 2014 Leave a comment

Sunday marked the start of International Dark Sky Week 20-26 April 2014, a global initiative to get people out of towns and cities and seeing a night sky as it’s meant to be seen, unspoiled by light pollution.

Most of us live in urban environments these days, with the ever-present orange glow lighting the night sky. From my garden in Glasgow I can see only a few hundred start on a clear night. But if I traveled south by car for an hour down to Galloway Forest Dark Sky Park, or north by the same distance to Loch Lomond National Park, I’d count thousands of stars.

DSA800x_202And then if I made more of an effort to get to the very darkest parts of our country (the heart of Galloway Forest, or Northumberland Dark Sky Park, or up to Coll Dark Sky Island) the number of stars would be overwhelming, too many to count.

At this time of year in the UK (especially in Scotland) you’ve got to wait until quite late to see the sky free of twilight (2230 in Exmoor Dark Sky Reserve for example, 2330 in Coll, and after midnight up in the Orkney Islands), but it’s worth making the effort if it’s clear.

If you do head out this week here are a few things to watch for:

 

The Lyrids meteor shower will reach its peak on 21/22 April but you might catch some early Lyrids in the days beforehand, and some after the peak; the darker your skies the more you’ll see.

Cygnus the Swan, and the other stars of the Summer triangle will be rising high in the east after midnight. In the right wing of the swan is the star Kepler-186, with the new-found twin Earth, known as Kepler-186f. The star is far, far too faint to see, even with a very powerful telescope, but you can still look in that direction and give a little wave.

 

Dark Sky Islands

There are only two International Dark Sky Islands in the world, and both of them are in the British Isles: Sark in the Channel Islands; and Coll in the Inner Hebrides.

Coll

They were designated by the IDA (the International Dark-sky Association) under their International Dark Sky Communities programme, Sark in 2011 and Coll in 2013.

These beautiful short films show what you’ll see on a clear night:

I’ve visited both islands several times, and they’re beautiful places, and not just at night when the stars come out. They’re very different: Sark is lush, with hedgerows and country lanes, and at 49°25’N latitude its climate is very continental. Coll on the other hand is almost entirely treeless, it’s rugged, boasts long sandy beaches, and lies at 56°38’N. Contrary to common impressions of the weather on the west of Scotland, Coll is one of the sunniest parts of Scotland and so has, like Sark, a high number of clear dark nights.

And it’s on dark nights when these islands are at their most stunning. Now that summer’s on its way though the dark nights will shorten and eventually disappear altogether until autumn, so you’ve plenty of time to plan your visit. Sark has a longer dark sky season, running from August till mid-May, as opposed to Coll’s which runs from September till mid-April, but the nights are longer on Coll than on Sark during the darkest winter months, the best time for stargazing.

Make sure that if you’re going to Sark or Coll for stargazing that you avoid the bright moon. Ideally you would be there during a new moon or thin crescent; at the very least you should avoid the week on either side of the full moon. To maximise your chances of seeing the wonderful dark skies make sure you stay for several nights!

Northumberland and Coll: The Newest International Dark Sky Places

December 9, 2013 2 comments

The International Dark-Sky Association (IDA) announced today it has designated two new International Dark Sky Places in the UK, including one representing the largest land area of protected night skies in all of Europe. This brings to six the total number of IDA International Dark Sky Places in the UK, second only to the United States.

IDA is proud to recognise Northumberland  Dark Sky Park and Coll Dark Sky Island for their exceptional efforts in helping preserve and promote dark night skies over Britain.  I have worked with both of these areas as a dark skies consultant, advising them on the process of achieving dark sky status. To date this puts the number of dark sky places that I have been heavily involved in to five; more than anyone else in the world, I think!

The reasons for these areas seeking dark sky status are many and varied. Off-season winter astronomy tourism is one main driver, while for councils the economic and environmental benefits of night-sky-friendly zero-waste lighting are paramount. Northumberland County Council have recently announced an investment of £24million to refit all public street lights in the county to energy efficient LED lights, fittings which pay back the initial investment within 6-8 years through reduced operating costs, and which have a significantly reduced carbon footprint, due to their efficiency and the fact that no light is wasted – it all shines down to the ground where it’s meant to be, rather than into the sky.

Northumberland International Dark Sky Park

A UK National Park and adjacent forestry plantation encompassing nearly 580 square miles (1500 km2) of public lands in northern England, Northumberland National Park and Kielder Water & Forest Park are the first IDA-recognized International Dark Sky Park consisting of two independent parkland units.

Once at the frontier of Roman Britain where Hadrian’s Wall repelled Pictish invaders, Northumberland International Dark Sky Park now serves as a bulwark against the incursion of harmful light pollution into one of the darkest locations in England.

With today’s IDA announcement, National Parks UK and Forestry Commission England adds dark skies to their portfolio of protected natural resources including the largest manmade woodland and reservoir in northern Europe. Kielder Forest provides Britain with 200 million board feet (475,000 m3) of timber annually.

The dark night sky attracts an increasing number of visitors to the region. Kielder Observatory, the UK’s largest and most active public observatory, widely promotes local astronomy events and activities. “Dark skies and astronomy have become a passion in the area,” according to Heidi Mottram, Chair of the Kielder Water and Forest Park Development Trust and Chief Executive of Northumbrian Water.

As both Northumberland National Park and Kielder Water & Forest Park began to vie independently for IDA recognition, it quickly became evident that two heads were better than one.  “It made perfect sense to work together to protect one of our greatest assets and make it available to more people,” Mottram said.

Park officials hope that protecting dark skies through the promotion of responsible outdoor lighting will increase the allure of Northumberland as a tourism destination.

“Becoming a Dark Sky Park will reinforce the status of Northumberland as an unspoiled destination offering a true sense of tranquility and wildness – a tonic in this day and age,” said Tony Gates, Chief Executive of Northumberland National Park.

Coll International Dark Sky Island

A sparse population and geographic isolation make the night skies over the Isle of Coll among the darkest in Europe. The island adopted a quality outdoor lighting management plan to ensure Coll remains dark for many future generations of residents and visitors.

Coll lies about six miles (10 km) west of coastal Argyll and hosts just over 200 residents. It attracts dozens of bird species according to the Royal Society for the Protection of Birds, which owns an extensive reserve at the west end of the island and hosts one of Coll’s recognized night sky viewing sites on its land. Nature tourism in part draws thousands of visitors to the island each year.

“Achieving dark skies status will be great for the island in many ways,” Julie Oliphant, hotelier at the Coll Hotel, explained. “Not only will it ensure that any future development on the island is done in a way that protects Coll’s natural and unspoiled beauty, but it will also help promote winter tourism.”

Fred Hall of the Argyll and Bute Council echoed the sentiment. “The Isle of Coll is a unique island in many ways, not least of which is its beautiful countryside and sea views but also the lack of light pollution,” he said. “I can think of no better island in the inner Hebrides to gain the Dark Skies accolade.”

Northumberland  is IDA’s thirteenth International Dark Sky Park, while the Isle of Coll becomes the world’s fifth International Dark Sky Community. They join four existing International Dark Sky Places in Britain: Galloway Forest Park in Scotland, Isle of Sark in the Channel Islands, Exmoor National Park in England, and Brecon Beacons National Park in Wales.

Stargazing Weekend Breaks 2013-14

October 19, 2013 Leave a comment

There’s a great piece in Guardian Travel today about stargazing breaks in and around Galloway Forest Dark Sky Park. The article was written by Kevin Rushby, who visited the park earlier this year, and who I took out stargazing on a beautiful night.

It really is an amazing place, and on a clear winter’s night you can see thousands of stars, the Milky Way, shooting stars, nebula, galaxies, satellites… and much more.

But for most people the night sky is a confusing place, and having a guide to lead you around is an ideal way to begin stargazing. (Ahem! A good guide book is handy too…) I run regular stargazing weekends and evenings at a number of hotels near Galloway Forest Dark Sky Park (and one down in Exmoor!) over the course of the winter. Here are the dates for the weekends I have planned for this coming winter:

1-3 November 2013 Selkirk Arms Hotel, Kirkcudbright
29 November – 1 December 2013 Kirroughtree House Hotel, Newton Stewart (SOLD OUT)
6-8 December 2013 Kirroughtree House Hotel, Newton Stewart
31 January 2013 – 2 February 2014 Yarn Market Hotel, Exmoor
28 February – 1 March 2014 Kirroughtree House Hotel, Newton Stewart
28-30 March 2014 Selkirk Arms Hotel, Kirkcudbright

I also run bespoke stargazing nights at Glenapp Castle, Ballantrae.

Light Pollution and the Loss of Wilderness

April 21, 2013 Leave a comment

Today marks the 175th anniversary of the birth of John Muir, the Scottish-born American naturalist, writer, and advocate for the preservation of wild land.

20130421-165126.jpg

The protection of our wildernesses landscapes (defined as anywhere you cannot see the intrusion of human activity) is more important than ever, with the spread of suburbia and the urbanisation of more than 50% of the world’s population.

But one measure of what makes a wilderness has to-date been largely ignored: that of the darkness of the night sky. After all, if you can see the sky glowing orange at night then you are seeing the intrusion of human activity, and you can’t consider the land you’re in a true wilderness.

John Muir’s legacy as the founding father of the conservation movement lives on today, in part in the organisation The John Muir Trust.

The JMT estimates that the amount of Scotland’s landscape that is wilderness is rapidly diminishing, dropping from 31% of Scotland to 28% between 2008 and 2009, but I think if you added in the spread of man-made light pollution the situation would be decidedly worse.

I am fortunate to have been awarded the JMT’s Bill Wallace award to help fund a trip later this year (once the skies get dark again after the bright summer nights) to map light pollution in one of Scotland’s most wild landscapes, between the JMT properties of Quinag and Sandwood Bay.

Hopefully this project – the first of its kind in this remote area – will shed some light on the problem of the loss of our wilderness nightscapes.

The Return of Darkness

August 21, 2012 2 comments

With summer coming to an end in the British Isles we start the return to the dark skies of autumn and winter. Depending on where you are in the country you will have been without truly dark skies for many weeks, maybe even months, as summer evening twilight lasts throughout the night during the summer.

This all-night-long twilight is almost gone throughout the UK, indeed anywhere on the mainland UK can see astronomically dark skies around 1am at the moment. Only the furthest north outpost of the British Isles still doesn’t have that opportunity.

On the island of Unst, the furthest north of the Shetland islands, lies the UK’s furthest-north town, Skaw, at 60°49’N and 00°47’W. This tiny village will see astronomical darkness return at 0043 on 24 August, lasting only 46 minutes until at 0129 the sun’s light begins to creep into the sky again.

The last time that astronomical darkness was seen at Skaw was on 18 April, over four months ago! Indeed this settlement is so far north that between around 13 and 29 June each year they never get out of civil twilight, meaning that the sky’s bright all night long!

Compare this with the furthest south town in the British Isles, Saint Clement in Jersey, in the Channel Islands. Astronomical darkness returned to Saint Clement on 4 July this year, having been absent since 8 June; only four weeks without true darkness!

Such is the effect of differences in latitude that these two settlements, separated by 1299 km, have such hugely different seasonal swings between summer and winter.

 

 

Scottish Dark Sky Observatory

July 18, 2012 1 comment

Last Saturday night I visited the site of the soon-to-be-open Scottish Dark Sky Observatory. Sitting on a hill top in Craigengillan Estate near Loch Doon, this stunning new public observatory lies on the edge of Galloway Forest Dark Sky Park, under some of the darkest skies in the UK.

At the moment the observatory is still under construction, and is due to open in a few months time, at the start of this winter dark sky season. It will be open to the public and school groups for day-time and night-time visits.

The site itself is wonderful, and the observatory is nestled amongst the graggy hill tops east of Ness Glen, just south of the small town of Dalmellington on the A713.

The observatory will include a fully robotic 20” Corrected Dall Kirkham telescope in a 5m dome, operated from either of two control rooms; a roll-off-roof observatory with a 10” SCT for a more hands-on, out in the open observing experience; a multi-purpose lecture room served by a toilet and kitchen and an “outdoor classroom” in the form of an elevated observing deck from which to enjoy the experience of naked-eye observation. Facilities will be provided for amateur astronomers to set up their own equipment and have access to the toilet and kitchen facilities. It will be open to the public, amateur astronomers and to schools and universities, with the aim of inspiring people of all ages and all backgrounds with a sense of wonder at the vastness and beauty of the heavens and the revelation of man’s place within the universe.

The Observatory was the brain child of Craigengillan Estate owner Mark Gibson and the Renfrewshire Astronomical Society (RAS). A member of the RAS, Colin Anderson, is an architect and he designed the buildings. It’s a tribute to Mark, Colin, and others in the RAS that this project is even possible, and I for one cannot wait to observe from their incredible new observatory.
