Three consecutive 25 second shots, 2 second delay between first two shots and an extra 10 second delay before the third image while I adjusted the focus (I was trying to find a precise infinity focus point) taken last Friday night at ISO 2200, Nikon D810, Rokinon 14mmED.
The intervalometer was set, I just sat back but did notice a bright spot appear in the sky, last x period of time, fade out and vanish (I was staring at the bright spot that just appeared, not my watch).
I had no idea I'd even captured it in an image.


These are only jpeg images my son put a box around the area to show no similarities. They are visually untouched other than the watermark and the rectangular boxes

I have the raw data on my pc and card

Bright spot appearing then disappearing sounds like iridium flares from older satellites that reflect the sun they appear to be a brighter almost flash tne settle down and disappear.

I thought about that but every other satellites that crossed the sky left steaks across my images as they traveled across the sky. And it appears to be close.

Geostationary satellite flare?

Hi Leo,
That is a very interesting pic !

There is no trail in the image before / after, so I doubt whether it is a satellite.

My guess is that your image is of a small meteorite entering the upper atmosphere.

Typically, these get really hot as they enter the atmosphere, leaving a bright streak, then they vaporise in a bright flash, then leave another streak as they cool down ...

These happen all the time, but not everyone is lucky enough to capture all three in one image

It's the asymmetry of it that I find fascinating. I don't know how anything that far away could have such clearly defined asymmetry, and it looks too small to be a local light reflection from, say a passing headlight.
Interesting...

[Leo.G (Leo)]

I was in my back yard right behind the house, no headlights, no street lights or other reflections and not house lighting.


I didn't include my image of a near earth space station (my TV antenna which looks so much like a space station in the image).


36.3 (or 36.6, I never remember) mega-pixel full frame sensor helps with the clarity I believe (Nikon D810).



It was just lucky, 25 second exposure, 14mm wide angle ED lens (f2.8 ISO 2200 and an intervalometer which happened to trigger the shutter at the precise timing. I wish I could get that lucky with lightning every time.

"LEOS" refers to Low Earth Orbit Satellite AKA TV antenna (while Leo just happens to be my name and I seem to exist in a Low Earth Orbit).
