Here's an interesting fisheye shot I took this morning - quite a bit of flare from the Sun, but not a single contrail!

Volcanic sunset on April 16th looking west over the Sperrin Mountains from Maghera. The Sun sports a faint 15 degree pillar. Within the vicinity of the Sun are 'cirrus-like' strips of cloud which looked like NLC bands visually, these have been visible for the last two evenings. Those bands are ash clouds which have been confirmed by atmospheric expert Les Cowley. They are located in the Troposphere. These strips were complimented by a 1.5 hour, orange, low elevation afterglow.

Great pictures all of you!

I saw similar clouds to like what you described and showed this evening.  This could be very interesting, I can't see the volcano and its effects disappearing any time soon, which means more volcsnic sunsets for a while yet! Smiley

the ash cloud from the Icelandic volcano is heading right over the UK and airports are cancelling flights
There is a danger from flying right through the ash cloud at a short distance - where the cloud is optically thick - but it takes a lot to stop a jet engine. The recorded examples of engine loss due to volcanic ash have been at ranges of tens of kilometres from the erupting volcano, not hundreds or thousands. Stopping flights in the UK is a gross over-reaction.

OTOH if if means no contrails blotting out the sky, I hope the volcano keeps erupting forever!



I agree,Brian OTT.  What I don't understand is why flights to Europe or even the US can't take off and stay at ,say, 15-17,000 feet (the ash ,I believe, is at 20,000 feet) and then when clear of the zone climb  to the 35,000 feet that the Trans-Atlantic flights travel at, same coming in, get well under the cloud,15,000 feet doesn't pose a danger I wouldn't have thought.What about the planes that us leave Southampton stay quite low and land at Dijon or even further south. Maybe it's my age but I've lost all confidence in authorities whatever body they are.

It's one of those no win situation for the authorities i'm afraid.   They play the safety card like they are doing now and ground flights which annoys the heck out of people, however if they allow flights to resume and a plane comes down / suffers engine damage then they will get hauled over the coals for letting planes take off...  They can't win.   Roll Eyes

Two images from the evening of the 16/4/10 showing the same possible ash clouds as in Martin's shots and the faint sun pillar. These are from the same shot and have been cropped.  Obviously there is ash in the atmosphere but it must not be at the right elevation or significant quantity out to my west as sunsets have been nothing out of the ordinary-buts there plenty of time yet in the days ahead and Eyjafjallajoekull continues to erupt. By the way has anyone tried to pronunce Eyjafjallajoekull ??   What a mouthfull!! Grin

Lovely colours,there's probably ash in there somewhere.

I had this link sent to me-some wonderful eruption photos.  http://www.swisseduc.ch/stromboli/perm/iceland/eyafallajokull_20100416-en.html

Lovely images Paul, definitely volcanic ash clouds in there in the form of those NLC-type strips.

Looking forward to seeing what this evening's sunset will produce.

Volcanic ash clouds in the sky here all day long, with halo too. They look like NLC bands and herringbone structure. Watch out this evening.
