It was a strange one in Birmingham this morning I witnessed a set clouds that i have never seen before

Firstly the speed at which they appeared the disappeared 13 Mins
They came out of a clear sky ( stars were visible)
Clear on SAT radar over the Midlands at the time
They appeared to be travelling Southwards ( so not like any NLC`s that i know about )

There was some chat in the facebook forum about what was being picked by the OSWIN radars, which is within a few degrees latitude of Birmingham

Opinions Welcome


 timelapse
13 mins over 27"
28mm 4".....4" @ f5.6  ISO 320 ( No visual enhancements)

 

Probably a type of cirrus Arnie,Sat i don't think will pick the up.

I didn't see those particular ones, but did spot what I think might have been cirrocumulus stratiformis or mamma. The pics below were taken at 3.02 and 3.14am respectively.

I should add that those cloud formations came and went fairly quickly- by 3.30am it had clouded over completely.

Thanks for the opinions and links posted.

General concensus is that it was a short lived  tropospheric clouds illuminated by light pollution

Still awaiting the latest AIM.....But cam across some good webcam links while trying to understand my time lapse

Going on that theory they will be back around by the weekend, where they will be clouded out.......By a couple of days of Massive thunder storms

RECORD COLD IN THE MESOSPHERE: It's getting cold in the mesosphere. Very cold. "At polar latitudes (60N-80N) temperatures have been breaking 14-year records in the last few days," says Lynn Harvey of the University of Colorado Laboratory for Atmospheric and Space Physics. This development is causing noctilucent clouds (NLCs) to spill out of the Arctic to middle latitudes.

The chart in the report is a week old, so don't quite understand the 'getting cold'. It is cold, surely.

Yes Rob... we were suffering the same fate just down the road in Brum. Curse of the clouds again

On a cheerier note the latest AIM looks a beauty....and on par with last year at this time

Looking at some forecast....dont.....but there may be a clearer slot Sat/Sun where by 'the law of Sod'.... the NLC`s wont show up

Keep the faith

While awaiting todays AIM

current_daisy08.thumb.png.0c0fa4ddea0e09c4a8289baca116af63.png

Wow using the clock system would have got me excited for tonight/morning....if that big, long arm @ 110`clock has held together then i would have expected a possible 'overheader'....and of course the radars at both 70°N and at 54°N to be indicating something.....Which they are

possible copyright issue prevent me from posting the latest signals...but can be found here...where both the latest signals MARRSY radar (70°N) and OSWIN radar ( 54°) are located

Edit; The Marrsy radar seems to be stuck atm

interested article concerning radar

Noctilucent clouds around the world

Can we use Radar echoes to predict NLCs?

As of yet, there is NO WAY to predict NLCs with 100% certainty. Radars like OSWIN (north Germany) or MAARSY (Arctic Norway) detect echoes in the upper atmosphere called PMSEs (Polar Mesospheric Summer Echoes). The signal from these radars are reflected by free electrons around ionized material. Scientific evidence show that the material can be ice crystals, which is what NLCs are made of, but also other carriers like large ion clusters. Although it is in German, Stefan Krause kindly shared the results of observations correlating echoes and the occurrence of NLCs (so in short, can we use echoes to predict NLCs?):

They found that between 2007 and 2019:
- 57% of the nights preceded by OSWIN echoes show visually confirmed NLCs.

- 34% of the days without echoes were followed by NLCs
- 80% of the NLC nights were preceded by echoes.
- Those figures might have been slightly underestimated due to some nights with clouds.

 

In addition, those RADAR measurements are taken directly above the station. Unless the display is strong and NLCs are visible overhead (rare), they are therefore relevant only for observers located south of those with a radius of about 100 to 600km, who might see the NLCs thanks to the incidence of the Sun. Radars can also detect echoes coming from ice particles that are too thin to reflect sunlight, so they are invisible.

So the conclusion to be drawn here is:
- Echoes cannot predict NLC display with 100% accuracy the following night.
- However echoes give quite a good chance to see NLCs the following night.
- The stronger the echoes, the better chance there is.

- Echoes can give an idea of 'local displays'.

So you can use the radar echoes if you like to give you an idea of what to expect (https://www.iap-kborn.de/forschung/abteilung-radarsondierungen/aktuelle-radarmessungen/oswin-mesosphaere/). Please don't get disappointed if you don't see NLCs after someone advertised strong echoes in this group! NLC season is so short already, so as soon as it is clear, take a chance and go outside, that remains the best way to see NLCs! Happy hunting!

I live on the West Coast of Scotland (few cloud breaks here and there) - just popped out and took these on my IPhone 11 Pro Max (night mode is pretty rubbish!) between 00:30 and 00:40. (Looking North/North East - my location is the red circle)

So the way I work these and I know people say you cant but here goes

Night/Morning of 8th/9th is at the 6pm Position

9th / 10th would be the 5pm position

10th/11th would be the 4pm position

11th/12th would be the 3pm Position (Tonight) and its why Scotland is doing so well with that chunk hanging just above 60 degrees North

So tomorrow if clear should also bear Fruit in the 2pm position

 

This theory has worked well since May 25th
