Noctilucent clouds - Austin Taylor

Sightings of these clouds are confined to the summer months and may be anticipated perhaps 3 or 4 times in an average year, though sightings are becoming more common - I have seen them 4 times this year already.  They are also normally a northern phenomenon, generally being confined to latitudes north of about 50 degrees - though they are increasingly being seen further south.  Sightings as brilliant as were visible on the 18th are rare and these were a truly beautiful sight for anyone fortunate to see them.  "Noctilucent" means "luminous at night" and they are only visible when lit from below after sunset, with the ground and lower atmosphere in darkness.

According to the British Astronomical Association, noctilucent clouds are located in the mesosphere, about 80-85km (50 miles) above the polar regions of the Earth's surface and are the highest clouds ever seen, some ten times higher than cirrus, the highest tropospheric cloud. They are still in sunlight long after sunset and they shine in the sky whereas the lower tropospheric clouds show up dark against them.

Other internet sources say that these clouds are extremely thin and tenuous, made of tiny ice crystals that brilliantly reflect sunlight.  Not a great deal is known about them and there seems to be some disagreement on how they have formed.  It seems that they were only first observed in the late 19th Century though there are suggestions that their development may be relevant to climate change and that sightings are becoming more frequent. Scientific research seems to be difficult, being too low for satellites to observe and too high for balloons to gather data.

'One of the coolest things in the sky', even with the tantalising glimpses an ornithological scope can manage.


Monday 3rd October 2005

Partial eclipse of the sun over Foula - Tony Mainwood


Tuesday 9th November 2004

A spectacular aurora almost filled the sky from just after sunset to just before dawn. Colours mainly varied from green to white, but there were some spectacular shapes.

 

Aurora over Haroldswick and Clibberswick - the constellations visible are the Plough in the first two, Gemini on the right of the third, Gemini and Auriga in the next two and the star Vega in Lyra is the most obvious star in the final photo - Mike Pennington

Aurora over Nesting - Bryan Gray


Tuesday 31st August 2004

A brief but spectacular aurora was reported over Lerwick at 01:30 this morning.

It was predicted by Aurora Watch - click here for a link.


Tuesday 8th June 2004

With sunny spells through the day there were good conditions for viewing the transit of Venus across the face of the Sun - an event not seen anywhere on Earth of 126  years.

The transit of Venus, the second showing the so-called 'third contact' when the disc of Venus comes into contact with the edge of the Sun's disc before leaving the face of the Sun - Austin Taylor (click on images for larger versions).


Monday 3rd May 2004

It was too cloudy to see the eclipse of the moon on the night of 4th/5th, although there was a fine night sky the night before.


Saturday 20th March 2004

A rather unusual set of circumstances over the next week or so allows an observer to see all five naked eye planets at dusk - Mercury is very low in the west and only visible for half an hour or so after it gets (fairly) dark, Venus is about as bright as it ever gets, Mars is fading fast but is easy to find just beneath the Pleiades (Seven Sisters), Saturn is high in the sky and Jupiter is in the east and almost as bright as Venus.


Thursday 20th November 2003

The best display of the Aurora Borealis ('Northern Lights' or, in Shetland, 'Merry Dancers') was witnessed throughout the islands. These photos were taken by Mike Pennington at Uyeasound.


Saturday 31st May 2003

The annular eclipse of the sun was affected by the cloud cover. A few lucky observers saw the 'golden ring' effect through the clouds. On Unst, this was the best view before the sun disappeared behind thick cloud.
