Aurora Borealis, Aug. 20, 2022

Last night, the auro­ra data looked good, and also the sky was clear (unlike oth­er nights late­ly). I packed my cam­era and tri­pod, then head­ed out to one of my favourite spots (Twin Pines Field, let’s call it) about 10:45pm.

The tem­per­a­ture dropped while I was out, going from about 24°C to 17°C. Every­thing got coat­ed with a slick of dew, including—as you can see in the last photo—my lens[1]Actu­al­ly, it was the trans­par­ent UV fil­ter over the lens, which was much eas­i­er to wipe clean. Phew..

All told, I shot almost a thou­sand images, each one a 5‑second expo­sure[2]Nerds: 11mm, 5s, f/2.8, ISO 3200., which con­ve­nient­ly means that mak­ing a time­lapse at 12 frames a sec­ond cre­ates a video where 1 sec­ond of video = 1 minute of real time. So my hour and twen­ty min­utes at Twin Pines Field con­dens­es into a minute and twen­ty sec­onds for your edutainment.

Enjoy!

Inter­est­ed in prints of my pho­tos? Let me know, and we can work some­thing out.
