A side note here, linking back to my own thread linking the photosphere to the chromorosphere and also apparently the zone of ionization where calcium atoms become singly ionized..

Just bagged 10 minutes between the clouds and got to see the Mercury shadow transit!
Its so long since I used the Lunt that I took a few seconds to get back into the groove of tuning the double stack and letting some air into the tuner as it was flat.
Not much else on the disc - 3 x sets of proms, 3 tiny filaments, saw one small bright flux patch briefly.
But the Mercury shadow was nice and clear and a decent sized patch too.
Just got back inside before it started spotting with rain! Fingers crossed for another clear patch later ...
We are hoping to observe the transit in school (Don’t panic - we have done several transits and partial eclipses in the past so we are fine on the safety aspects - thanks). However does anyone know how I can get hold of some links to use in advance of the day that we can use to put some professional feeds up on the large screen tellies we have linked up to the computer systems these days – I am told that links on YouTube are the easiest to handle on the slightly clunky system we have to control them.
My question comes from reminiscing with colleges that my daughter and I had stayed up to watch first contact of the last transit of Venus live from Hawaii before swapping to Mt Wilson. (We were also up before dawn on top of the local hill fort as the sun rose having lugged an old 4” reflector up there.) Of course at the time we were just browsing through the internet not taking good note of sites we were on.
