A little lunchtime project. With the help of the chemistry techs, a go at wet silvering and old 16in cassegrain mirror. Not perfect but not bad for a first attempt! A few tweaks to the process needed. #astronomy #telescopemaking

Sitting under a "cloudy high" pressure system often has extensive sheets of stratus. During a recent flight these clouds look remarkable from above. Also a bit further south altocumulus castellanus at a weak frontal instability. @CloudAppSoc @metoffice @bbcweather

Have just spent an amazing time at the archive of the Royal Greenwich Museum examining the first meteor spectroscope in the world. Built for and used by Alexander Herschel to study the Leonid storm of 1866 from Glasgow. Wonderful. @AstronomyNow @RoyalAstroSoc @AstronomyMag

Despite fairly poor conditions I did get one decent Perseid spectrum. Typical ionised Ca, ionised Si and H emmission. #Perseids #meteorshower @AstronomyNow @BBCScotWeather @jimalkhalili @RoyalAstroSoc

Now you see them, now you don't. Images investigating nlc particle size. #NLC ice particles are tiny! So small they are transparent to light ~1000nm!.Instead, cirrus clouds glow brightly. These are the same FOV less than 1 minute apart!

Just checked my screen. This is the hottest temp I've ever recorded in Kilwinning at 34.5c! @metoffice @BBCScotWeather @bbcweather #heatwave2025 🥵

Have just spent some time with the current owner of Glenlair House, Mr Duncan Ferguson, the ancestral home of the Scottish physicist James Clerk Maxwell. An astonishing and incredibly beautiful place! #JamesClerkMaxwell

A fantastic #NLC last night. Large diffuse features that developed throughout the night. Up to 60 deg and az 320 to 120 deg by 0230ut. @nlcnet Distinct bluish veil over whole display. Display brightened considerably as display expanded.

Gorgeous #NLC seen from North Ayrshire now. 2am local. @nlcnet

Fairly diffuse #nlc last night. Height to around 20deg and azi to ~40 degrees. @nlcnet

Dramatic sky over Kilwinning!.Mama and strong windblown striations. #clouds @metoffice @CloudAppSoc @bbcweather @BBCScotWeather

A picture from last night. #NLC at around 2am.

Finally got my first #NLC of the 2025. The NLC forum is still active and don't forget to upload observation and pics at noctilucent cloud observers homepage.

Dear @UPS_UK found one of your "sorry we missed you" notes through my door. Expecting a few parcels but just what am I supposed to do with this. ? There's nothing on it. QR code just takes me to your tracking page but I don't have any info to enter. Utterly useless!!!

Don't forget the next International Meteor Conference is from Sept 18th - 21st in Soest, the Netherlands. @popastro @AstronomyNow @RoyalAstroSoc @BritAstro #meteors #fireballs @IMOmeteors . ✈☄☄☄☄☄☄.

A WINNING score certificate! The fact that I was the only GM in this category has absolutely nothing to do with it! 🤣🤣🤣🤣🤣

Perhaps only the second time a curvy meteor has been caught on video. (See ( Turns out I also got the spectrum!, although extremely faint (far left of image) turns out this one was pure Fe. @SkyandTelescope @AstronomyMag #fireballs #meteors

The power of spectroscopy! Two lovely bright meteors that look pretty much the same to the eye. Turns out they are completely different. One is rock the other iron. #1 is Type A, #2 is Type B @SkyandTelescope @RoyalAstroSoc #meteors #fireballs @jimalkhalili @AstronomyNow

A beautiful night and captured a rare pure iron meteor spectrum. Blue/green lines all Fe. The bright yellow/orange part is huge thermal emission. Exactly the same principle as filament bulbs! @BritAstro @RoyalAstroSoc @popastro @AstronomyNow @SkyandTelescope #meteors #fireball
