The first (seen in the first animation) took place on September 7 and the second one on the November 2. People though these were some planes crashing, but were later confirmed to be small meteor showers.
Just so you know, this happens all the time in our atmosphere and there is nothing to be alarmed about. Albeit, legion of these meteors enter the atmosphere, most of them are burned away in the outer strata of our atmosphere. But some produce streaks in the sky that can be visualized. And finally a few do manage to make it to the surface of the Earth, but those are a rarity.
