Visibility III / V
Not a fireball, but a nice-length stellar flight was recorded in three exposures as I was shooting a Northern Lights-time child. Vanana showed small brightening spots in the eye.
Four-second exposures every 10 seconds: the first at 22:13:40, the second at 22:13:50, and the third at 22:14:00.
NOTE! Since the Sky Watcher maintains that this is NOT a starburst ("We suspected there could be no starburst here, as more than 20s is a remarkably atypical duration for a starburst.") - and therefore the observation was classified by them as northern lights - I hope for views on what it is. In my opinion, it has a falling song. It left behind a blaze of fire, from which, in the final stage, small brightening points stood out to the eye. Can someone know how to calculate the speed of movement with the given information? In my opinion, it fit the falling song very well. Extinguished with fading.
The original size versions of the images can now be seen here, where I have emphasized the contrast a bit.
I guess ‘remarkably atypical’ doesn’t mean ‘impossible’? :-)
17.10: I added pictures # 4 (magnification from picture # 1) and 5 (magnification from picture 3).
17.10: Referring to Esko Lyytinen's comment at 4.43 pm, I added picture no. 6, which is the next exposure in the time lapse series after image # 3 (same six-second pause as before)
