OK, What's this ?

Hi,

Last evening i did a short session on M45 as it's shifting towards the west witch is not the best direction for me.

Anyway, as i was checking my frames i noticed something on one of them, three stars seemed to appear out of nothing.

This is strange i think, a satellite or plane would leave a streak no ?

Check it out, these are two 5min subs

 

 

Anyone ?

It certainly looks like something travelling in a straight line. My guess would be something that is flashing a light and hence no streaks just points.

Are there satellites with flashing lights ?

[DarkAntimatter]

Maybe a high plane?

Give us a time and date and will see if any sats passed by.

Don’t forget that’s 20h03 on the island..

Yes, defrinitely an intermittent light travelling in a straight line - my guess would be a flashing light as something rolling would not give pinpont results.

Globalstar M068 passed in that direction from bottom to top.

Ok thanks, does this Satellite blink every 1,xx minutes ? 

Edit : The Sky.org states its inactive

No, globalstar satellites (and satellites more in general) typically do not blink. I'm pretty sure that a Globalstar would appear as a straight line. 

A single axis satellite could appear to blink due to its rotation and reflect the sun towards your direction only at specific angles, but globalstar are three axis stabilised , so this isn't the case. 

Some sats embark laser retroreflectors, to send back to Earth a laser radiation pointed towards them, but you need to be very close to the Earth station to receive it, and i don't know if this would appear in a photo... You would probably rather see the upgoing beam, which isn't the case. 

Maybe a rotating debris? Like a launcher second stage or part of a fairing?

Some satellites do flash, have observed several while imaging, the longest set was 11 flashes.

Some Globalstars do flash as they are out of control.

Have just run the sats with new keps on my office laptop here at work and this sat does'nt show now, going to investigate
why two laptops show different things.

Well, yes... I was referring to OPERATIONAL satellites clearly! ? ? ?
