Flashing Star? one for the experts

[Photosbykev]

During a lot of recent timelapsing I noticed something odd in one image. Where there wasn't a star a 'star' appeared and then disappeared i.e. the first 30 second exposure didn't have a star, the 2nd exposure did and the third one didn't ???

Any thoughts because it stumped me, it doesn't appear when I use Novametry to check the area so I'm lost.

The 1st 30 second image

The 2nd exposure

and the third one

with the Novemetry result below

No idea but looks spooky.

Not an expert, my first thought was a Perseid that got into shot at the very first moment as the shutter opened. Thus no trail, just the final light point?

[Laurie61]

It could be a head on meteor, I have seen a few recorded on my video set up.

NGC 6118

No idea where it is but also known as the blinking galaxy

That's my best effort. Probably a mile out but felt good contributing something. :)

That's a possible, or a pinpoint meteor from another source.

Head on meteor would be my guess as well

[Photosbykev]

ok my second camera also pick it up as a pin point so that knocks the 'last part of a meteor' theory because the two cameras wouldn't be that synchronised.

Looking closer at the 'star' there is no trailing on it like the adjacent stars so maybe the pinpoint meteor theory is good?

Satellite flare?

I saw seven, very bright, flashes (two in pairs) while looking for perseids with no sign of a satellite. I also saw one satellite that flared very brightly twice (once REALLY bright).

Yes I'd go with a satellite or piece of space junk just catching the sun for a moment, it happens all the time and normally you don't notice. I collect data from my AllSky camera every clear night and I've got so used to seeing these things (and weirder ones!), I particularly like to see the rapidly tumbling satellites as they cross the sky.

My first thought from the description was the "Blinking Nebula" which is a visual illusion - NGC6826 - see here:

Dunno if it's in the same area you were looking but hope that helps - if not then it's one to look for.

[Welrod50]

I initially thought 'stuck pixel' until I read that you got it on another camera.  Space junk maybe then??

[Photosbykev]

and I caught it on a 3rd camera as well, a Panasonic Lumix FZ-1000 bridge camera  I think I need to sync my camera clocks a bit more accurately lol

[Pete Presland]

I have no idea what the "blinking object" is, but they very good milky way images anyway!

Fascinating thread.  Cool images too, will be following this one to see what other ideas crop up. 

[Astroscot2]

Kevin, I recon its a slow moving satellite/space junk too, Ive witnessed somthing similar a few years back and watched through binos as a satellite moved extreamly slowly across the field of view while brightning and dimming. The movement was just detectable in the binos,  Ive never see anything like it since.  Can you overlap the images to see any movement ? I suspect I can see some.

I do like a mystery

That's a good point.  

It could be space junk or a satelitte that is rotating and parts of it are more reflective of the Sun than others.

Reading this thread reminds me of Trigger in Only Fools and Horses looking at a star through the window.  There it is.....it's gone again........there it is again..... etc

Geostationary timbling satellite maybe ??

[Lewis Mark Williams]

Tumbling i meant lol

[lukebl]

I'd say reflection from a geostationary satellite too. They orbit above the equator, and when viewed from the UK appear a few degrees south of the celestial equator due to parallax. That looks pretty good for your object.

[Photosbykev]

There aren't any geostationary or orbiting satellites at that location in the sky, I've check through all the databases I have access to and the nearest satellite is about 1 degree away from the point of light.
