I first noticed this bright star looking thing on the evening of the 4th september 2020 out of my flat window. there were no other visible stars in the sky so i decided to use my phone to zoom in on it. when zooming i noticed that this bright star was chaging size whilst seemingly exploding. it also appeared to be spinning like some sort of spiral. the first thing that came to mind was the videos captured by commercial airline pilots on the tv programme unidentified. it seems to be to be identical to those. the bright light remained in the sky for around an hour before dissapearing. i checked out of my window again every night and did not see it again until saturday the 10th october at around 8:30pm again. when zooming in the light behaved in exactly the same manner, jumping around exploding getting bigger and smaller, also spinning or spiralling again. the light seemed to remain stationary in the sky with very little movement. i checked out of my windown again on the next night (sun 11th october) but it wasn't there. however, last night (mon 12th october) it appeared again with the same characteristics. i have videos of all 3 events. i am only able to send a short video as the other longer ones are unable to upload. i have longer video's with better detail.
