This came across my timeline tonight.. 4 years ago we were coming out of lockdown and saying thank you

I've started uploading some of the timelapses and real time videos I shot during last week's big auroral display to my youtube channel. Check them out at this link https://www.youtube.com/watch?v=ti6nNjyD8U8

So yes. I’m getting up at ungodly o clock tomorrow to watch Arsenal play honourably. Man City have been financially doping for years and (surprise surprise) haven’t had points deducted because they have huge resources. Would be sooo funny if Citeh lose though. #arsenal

I'm slowly going through aurora images from last Saturday night. Here's an image I thought I would never see. An auroral arc low in the NORTHERN sky in front of the SAR Arc!

@MikeBartley yes that’s the SAR arc

Here's a panoramic image I took from my back garden of last night's auroral display

Last night the aurora was lovely, so, rather than heading somewhere remote, I sat in my back garden and enjoyed the view. Here's a 90 minute exposure taken twixt 22:22 and 23:52. #Startrails #aurora #auroraaustralis

No 2.5 hour road trip to witness an aurora last night. I slummed it in my back garden!

Aurora over my house this evening. Epic!

@mlanger I have no need for companies that exploit workers and destroy the night sky. I rather suspect the world could very easily do without both and be a better place for it :-)

Yeeeeehaw! Aurora Australis exploding right now! #aurora #auroraaustralis

@BobLefridge I’m basically in my garden not gardening and photographing auroras

Another day another aurora here in New Zealand’s Deep South

i also managed to image this afternoon's ISS solar transit using my Hydrogen Alpha Telescope. The detail on the solar disk is fascinating! #ISS #spacestation #astronomy

@iangriffin@mastodon.nz avatar

Boom. Not the best Space Station solar Transit ever, but I managed to spot this one from my garden. At the time the ISS was just over 1000km away from my location. This is a composite image

Astronomy dog, Connie Springer, has arrived to supervise the transit observations.

Ten minutes before The International Space Station transits the sun as seen from my garden!

@iangriffin@mastodon.nz avatar

Just because I am taking a day off today, and am waiting to watch the Space Station cross the sun, here's a comparison between radiation levels you get when flying on an ATR 72 and an A320 Airbus.

iangriffin, to NewZealand
@iangriffin@mastodon.nz avatar

This is quite interesting. (no... really!) I recently persuaded a colleague to take my pet Geiger counter from Dunedin to Apia via Auckland. The latitude dependency of the radiation exposure is fascinating!

iangriffin,
@iangriffin@mastodon.nz avatar

@_thegeoff yes also multiple flights :-)

iangriffin,
@iangriffin@mastodon.nz avatar

@silberspur Yes, sorry... the graph shows 4 flights with the "baseline" just before and after they took off which is the background level. Flights got to ~35K feet altitude...

iangriffin,
@iangriffin@mastodon.nz avatar

@_thegeoff The x axis is minutes but the time between flights has been cut out for the charts (Geiger counter turned on just before each flight and off after flight landed).
