Experience Level2/5
RemarksThe object disappeared after the explosion. I cannot say it was an explosion because there was no sound and the color was white, but I don't really know how to estimate its height to determine if it exploded at the entrance of the atmosphere. The sky was not cloudy at all, no moon visible from my view. The approximate diameter of the explosion (white circle) was 1cm from my point of view. The diameter of the object itself was like a basic star you can see with the naked eye, a lot less than 1mm. No trail seen. The explosion was sudden, instant, the fading of the explosion was quick, less than one second but you could notice it with the naked eye (I would say about 0.7 seconds)

RemarksThe little not-that-bright star was moving, I thought it was a sattelite but suddenly instead of the object it "exploded" into a relatively big circle with a little curve from the direction it came (just like the bite from the apple logo), after a few milisecunda the curve was gone and it was just a circle that faded from out to interior
