While observing the sky at night with my brother, we saw two unblieveble fast separating dots of light in opposite directions far away in the sky, with magnitude and size similar to the stars's in the background. At first glance, the dots were combined into one much luminous object before they split at an imaginary speed that did not suggest they were meteors or satellites. One of them disapeared in 5s after taking course to the est and the second one set off quickly at the same speed of the other dot to the west and stopped abruptly but kept gradualy decreasing its size and luminosity for about a quarter minute and disapeared after that. I'm not sure about the day mentioned above but it was nearly the end of the month.
