Yesterday, I was just star gazing and I noticed some star-like object moving with a high speed somewhere near the Orion's Belt and exhibiting all the seven colors i.e VIBGYOR and after a few moments, it disappeared. Any plausible explanations for this observation?

  • $\begingroup$ If it appeared to be moving fast, then it was probably nearby. Maybe someone goofing around with a quad-copter with multi-coloured LEDs. Forget it. In any case, how do you distinguish indigo from violet? $\endgroup$

  • $\begingroup$ Well, I was trying to say that it exhibited random colors every second. This was observed three days ago in Chennai near the Orion's Belt. $\endgroup$ Feb 8, 2018 at 14:32

    $\begingroup$ I'm voting to close this question as off-topic because starlike objects that are changing colour rapidly cannot be astronomical. Please look at the other UFO reports here to see why we can't answer them. $\endgroup$

Probably a satellite flare

It sounds like a satellite flare.

Coming, showing up clearly for a few moments, moving, then going away, are characteristic of a satellite flare, like Iridium flashes.

Check Heavens Above or any other similar site to see if any predicted flares match with your location and time.

The changing colours can be explained with "Twinkling".
