The run up to the Perseid peak was not good. However last night I got one good fireball spectrum showing the typical characterisitics of the Perseids. Strong ionised Ca and ionised Si and H emission.

Some nice #noctilucentclouds last night seen from North Ayrshire. If you see #NLC post your pictures and observations on the NLC Observers Forum ed-co.net/nlcnet/

The power of spectroscopy! two lovely bright meteors (fireballs?) that look pretty much the same to the eye but...
Turns out they are completely different. The first is made of rock the second pure iron! #astronomy #meteors #fireballs
Meteor 1 is Type A, meteor 2 is type B.

The observers in the UKMON network caught the Type B Fe meteor and determined an orbit.
Low inclination of 10 degrees and very slow at 10.6km/sec. Plot courtesy of the UKMON data base (Thanks UKMON!).
Orbit indicates probable asteroidal origin. #astronomy #meteors @europlanetmedia.bsky.social

A beautiful night and quite a rare capture. A lovely Type B pure iron meteor spectrum #astronomy #meteor #fireball
The iron lines are very prominent in the blue/green part of the spectrum and the yellow/orange part is mostly thermal emission with fewer discrete lines.

Another super high res meteor spectrum. Zero order video is here youtu.be/dEdURA38M9o?...
First time I've managed to fully resolve the Mg Triplet!

Time to put the lights on my big dish antenna... happy winter solstice. #astronomy #hamradio
... and a Merry Christmas and Happy New Year too.

...and another two... #geminidmeteorshower #astronomy #planetaryscience #meteors #fireballs #skyandtelescope

The article in S+T says 80% of Geminids are sodium free and my spectrum is unusual. I think this is a myth! I've NEVER captured any Geminid spectrum that has been completely sodium free! #geminidmeteorshower A few from this year..., all with sodium emission (Na)! #astronomy #planetaryscience

After miserable weather, it cleared for just a couple of hours and luckily right at the peak of the Geminid meteor shower!🙂
Caught about 30 Geminids and this gorgeous spectrum of a Geminid fireball on HiReMS. #astronomy #meteors #fireball #geminidmeteorshower #planetaryscience

Fame at last...!? 😉😂 Some of my meteor spectra have been used to illustrate an article in Decembers Sky and Telescope!

Captured a gorgeous full visible range #fireball spectrum this evening on a HiReMS system. Classic Type A, with strong Mg and Na lines. #meteors @royalastrosoc.bsky.social

Just beautiful!☄️😃

Another beautiful spectrum! A typical rocky Type A with strong magnesium, sodium and iron lines.
The UK Meteor Data Archive classes this as a Southern Chi Orionid, absolute mag of -4 #Fireball #meteors
Fantastic!

Despite the full moon, the Leonid meteor shower has produced some good results.
I captured this unusual spectrum this morning. 😃
It has been identified as a Leonid thanks to the reports on the UKMON website.👍
Lots of interesting lines to be investigated...

Here's a synthetic colourised spectrum of the fireball image I posted. Spans ~420nm to 591nm. Incredible detail! Most of the lines here are from iron atoms. #fireballs #meteors

Hello Bluesky! I'm an astronomer in Scotland. Here's the most detailed spectrum of a meteor ever captured! Very lucky catch and incredibly detailed. #meteors #fireball @aasoffice.bsky.social
