Title: 2011 Noctilucent Cloud Season
Post by: martinastro on May 17, 2011, 03:18:25 pm
It's that time of year again so a new thread has been started to share your NLC images, videos, reports, comments, thoughts, links, and alerts. Please post all NLC related imagery in this thread so we can keep things tidy and have a nice resource to look back on. With increased solar activity this season is not expected to be a good one however these night shining clouds are very unpredictable so no one knows what to expect which will make the NLCs of 2011 even more exciting. The typical season runs from late May to early August so the first displays are likely any night now so keep an eye on the twilight sky after sunset and again before dawn. Good luck and clear skies  :)

Thanks for the heads-up Martin and for the additional information via your website, I shall be certainly observing each night in hope, I have never witnessed NLC before not sure my home location is suitable though.

I've been looking every clear night (of which there haven't been many!) since the end of April, and there's been nothing.   I want to be personally more active this years season, various reasons last year meant I didn't see many NLC. 

If you're after a heads up as to whether anything is visible or not there is the NLC forum http://nlcnet.proboards.com/index.cgi   Sightings can also be reported here if you wish http://www.kersland.plus.com/nlcreps.htm

I am informed that we should have the radar temperature data available within a couple of days which should give us a rough indication of when we might expect the season to kick off!  As soon as I know anything I will pass the info on.

All you need location wise Anton is somewhere with a decent NW to NE horizon...

Another lovely clear night last night (24th), sadly no NLC visible yet, however the twilight arch looks glorious!  Not long now!!!  ;)

First sighting of the season from Russia http://nlcnet.proboards.com/index.cgi?board=2011nlc&action=display&thread=648&page=1

Time to start looking when the skies finally clear!

*edit* also confirmed from Denmark and Moscow...

Alan Tough got photos of NLC visible from Scotland.  Game on indeed!   ;D  ;D  ;D

Poor conditions tonight with some high cloud & lumps of decaying shower cloud but NLC positive at 2330 (May 30th) - a smooth band / arc about 3 deg high in the north, less high to the west & east of north, the arc is about 2 deg in height. Very faint indication of rays from the northern horizon stretching up towards Cassiopeia but I think these are high cloud (cirrostratus) illuminated by twilight rather than auroral in nature.

Edit: Hmmm, reviewing images I'm no longer so sure ... maybe the arc is just shadowing by cirrostratus. Judge for yourself.

I was at the north coast last night all night long and saw no NLCs at all, however there was a slight enhancement to the twilight above the horizon however that looked normal to me. I saw the streaks too, they were distant cirrostratus drawn into streaks by the jet stream and their shadowing generated that enchancement. Lovely sky last night all the same. Cool images by the way guys which really show that variation in brightness extremely well  :)


Title: Re: 2011 Noctilucent Cloud Season
Post by: markt on May 31, 2011, 05:31:23 pm
Nice images guys!  I think in Brians it's the twilight arch in cirrus, though does appear to be something faint in Pauls.  I'm on the north coast of Norfolk atm, bout 100yards from the beach.  Today has been gloriouslly sunny and tonight promises to be clear.  Camera is charged so will be heading off down to see what I can see after sunset...  Fingers crossed for something good tonight and in the nights ahead with this high pressure that has developed...  ::)

Having seen NLC's for the first time last year I'll definitely be  on the look out this time and will recognise them this time too.

Just saw my 1st NLC display of the season, and quite nice it was too, 01.09 - > 03.00 BST, type 3 brightness, with band (II) and wave structure (III), 20 deg high and 100 deg in azimuth from N to NE through Auriga, Perseus, Aries, Pisces. Images taken.

Lovely display, was not really sure if it was going to happen at all and should go to bed but surely did. Too images at the beautiful Lough Talt and Charlestown Co Mayo, also took a fixed tripod image of Milky Way even got the stars of Saggatirus (The Teapot) reflected on the lake.

Thanks everyone  :)

Paul, beautiful selection of images, you got really nice structure there and all captured from a great viewpoint. I really like the shot of the road in the foreground lit by the car headlights  :)

Post by: markt on June 03, 2011, 09:53:41 pm
You guys have got some fantastic shots I have to say!  I just hope tonight is as fruitful, worth keeping an eye on Spaceweather aswell this evening and over the weekend, they're forecasting a 45% chance of geomagnetic activity.  Would be a lovely bonus, a nice green auroral arc crowned off with NLC...

Looks like a very good start -  all lovely images including yours,Paul. You seem to do well over there for NLC's. I'll wait till I've finished all this editing, there's a lot to do and it can leave me quite tired but plenty of ops. for NLC's to come I'm, sure.

In Keeping with the NCL thread another display tonight June 11, 01.00, looked like it was going to be big and bright but not to be, but photogenic either way.

Was just going to bed and looked out and WOW!, I'm sure this has been seen around the country tonight, such a brilliantly bright display, looed a bit like a mushroom cloud with all its structure.

Very nice Paul, I was looking just before bed around midnight and wondering, problem is from my light polluted, horizon restricted city scape it's difficult to be sure...

Quite a nice display last night, with the Sun so far north the NLC was noticeable even at local midnight. The best display seemed to be around 0115 - 0130 UT after which the brightening twilight robbed the NLC of its full splendour.

The main display here was just to the west of north, with no activity east of Capella. Time lapse images show the NLC moving at an apparently fairly slow rate from NE to SW. Three sample images:

(http://i885.photobucket.com/albums/ac55/bjb11213/2011/June/14/IMG_0038.jpg)

Canon 40D, 17mm, ISO 400, various exposures (8 sec to 5 sec) at f/5.6 (evaluative auto exposure used)

Post by: martinastro on June 14, 2011, 11:16:38 am
Paul, awesome image, it was really worth the effort going to the lake last night, the reflection is absolutely perfect, really love this image. Bet the atmosphere was amazing with the moon up too. Congrats on a great shoot.  :)

Brian, nice image, I was wondering what the view from the coast was like, wish I had been there.

A nice display on June 13th/14th visible from 01.01 - 02.15 BST, it was visible for longer than this but I called it a night at the latter. Type 3 brightness, 15 degs high, +100 degs in azimuth, NW to N sectors with subtle blue and pearly white colour. Very nice whirls, waves, knots, and bands on view. Great atmosphere standing in a field watching them creep below Capella while the golden near-full Moon illuminated the the land in it's soft warm light behind me.

Thanks all, a great little find this lake i must say and to think its only 10 miles away and last night was my first time there (shame on me).  The combination of moonlight, mist hanging over the water and the NLC made for a wonderful experience.   Heres a few more..

Those images are stunning Paul, it really is hard to top NLCs and reflections on water, top quality photography!. I really love the first and last images, I can see the craftmanship in the 11mm lens. Congats on a stunning night's shooting. We will definitely need to meet up sometime.  :)

Only getting a chance to post these up now, this is the morning of he 18th June taken around 03:00. I had consumed a few beers earlier in the night so couldnt get to a scenic location, these taken in my front garden from town. Quite an extensive display and quite bright towards the horizon.

 What a wonderful set of images - I've just been back through the thread - it looks like a good season so far .That bridge photo is a great shot,Martin and your photos,Paul are really impressive too - being up at 3.00am  to photograph them is impressive in itself as far as I'm concerned Lol.


Title: Re: 2011 Noctilucent Cloud Season
Post by: markt on June 21, 2011, 07:09:38 am
It is great to see how this thread evolves and how the images keep rolling in.   I've only had a couple of views that hint at NLC this season, my northern horizon is rubbish - the weather hasn't been ideal either.  Still, hope it will improve before too long.


Title: Re: 2011 Noctilucent Cloud Season
Post by: JohnC on June 21, 2011, 10:39:16 pm
No improvement  this week, ,Mark. It's been awful  here for sky viewing lately and more overcast skies to come..you'd expect better in mid-June.You'll have to move house so you get a good northern aspect   ;D

Jun 28/29: Much interference from tropospheric cloud (socked in completely from 0030 UT) but NLC seen, a bright band low on the northern horizon from 2300 to 2315, more extended but fainter swirls & bands in the NNW gradually fading from 2345 onwards.

July 02/03: Very bad interference from "nasty low cloud" but from 0100 - 0130 UT there was obvious NLC, exceptionally bright swirls visible through & between patches of stratocumulus to an altitude of 20 degrees between North by West and North North East (solid cloud to the west of that).

Absolute stunners Jonathan! annoying low cloud here on the northern horizon until around 02:30 when it started to shift. A few images here taken at home over the rooftops with pesky tv aerials on view, but a beauty of a display none the less.

Nice capture - I'd have been tempted to crop out  half the black foreground. Where are you  btw ? No location under your name.

Unexpected mostly clear night with bright NLC in the NNE (stretching from NNW to just E of NE). Substantial low cloud on the horizon but I managed to grab this shot:

Jul 10, 0144 UT. Canon 40D, 17mm, 2.5 sec at f/5.6, ISO 400.

The "bright" cloud stretching across the top of the frame is tropospheric cirrus cloud, probably a smeared contrail.

Nice shot Brian, I kept looking out last night till 3am, however I guess my urban skyscape hid the show behind the rooftops....

Hey guys,
Those are very good displays you've captured!  8)

First NLC was reported from Kyiv, Ukraine on July 10th morning. Still I see nothing from Poltava... pity to tell you, I am rarely able to do it at dawn this year.  :-\

Clear sky from midnight on last night (Jul 22/23) and partially clear especially on the northern horizon tonight (Jul 23/24). No trace of NLC detected.

Jul 26/7 - clear all night & pretty transparent, in fact it almost went dark!!!  NLC negative again. Season over?

Haven't see any NLCs since July 9th/10th which is shocking, however this is more to do with cloud cover than anything else. The season will soon be ending so fingers crossed for another good one before it's over for another year. The best display of 2011 so far for me was on July 9th/10th, Roisin and I spent the night at the north coast watching it glowing over the sea and the infamous 17th century ruins of Dunluce Castle which made for a fantastic NLC experience. Here's a detailed report on my site with many more images....

Cheers Mark, haven't seen any more displays since then due to all the cloudy weather. I'm in aurora mode now  :)

That's a novel, Martin-brilliant. You should write a book sometime. Great photos too. but what a shame the season is coming to an end,we've had far too much cloud cover this year.

Thanks for the kind words John, a novel lol - that's a new one for me, I must take note of that for future inspiration. Pity the season is ending however one good thing ending often opens the door to some new good thing...and this time its aurora season  :)

Hey folks, been a long while! I saw NLCs this year on two occasions. Night of July 1 and July 2 very early AM. only 5 hours inbetween observations. I've watched quite a few nights this year and it was nice for it to pay off! even though they were very dim/small displays. Here's one from July 2 at 420am. These were observed at 44 degrees north latitude.

Brilliant photographs Martin, and equally impressive narrative to combine the two, makes me feel as if I were there.

Good to see you have seen some NLC's at 44 N Tyler. They had some up around Portland ,OR probably about the same time, about the same latitude. I keep checking in on your website to follow what you're up to.

Thanks Richard for checking it out  :)

Tyler, congrats on the NLC captures, very nice wave structure there, brilliant to see NLCs appearing so far south in the US and I'm delighted you have ticked them off your list, now I'm sure you will be on full aurora alert on the nights ahead  :)
