Name Alex G
Experience Level 2/5
Remarks I have seen a few shooting stars before, but I have never seen anything like this. It was very bright, very fast, and the pulse in size and light halfway through (and at the end) of its trajectory was very marked. I am was anticipating hearing a boom of some kind but did not.
