Just for fun. I added together all of the images I took of Comet Pons Brooks a few weeks ago. The session was just after astronomical twilight and every single frame I took (68) had at least one satellite trail. To really piss me off, a whole train of freshly launched Starlink satellites joined the "party". This, friends, is the price we pay for "progress". #notostarlink#savethesky
@M0CUV@Dtl median combing the images (after aligning them so the comet is in the same place gets rid of most of the streaks. But comets at their brightest tend to be close(ish) to the sun and are impacted by these trails a lot!
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!
@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 :-)
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! #radiation#NewZealand#physics
@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...
@_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).
Coronal Aurora, as seen from Lake Aviemore, 00:34 on 12/5/2024. In a coronal aurora, lines converge at the magnetic zenith in a stunning "crown" shape It's beautiful #aurora#auroraaustralis#NewZealand
i just realised I took 15,000 images during last night's auroral display. Here's another one, this taken at 00:27 with an exposure of 2.5 seconds. #Beauty#aurora#astronomy#newzealand
