Reports Report 631dg (Event 631-2016)

Observer
Name Mathieu R
Experience Level 2/5
Remarks I am a hundred percent sure it was a quite big meteor and not a small shooting star or a fireworks. I am used to see small shooting stars around 15th august in France and this was not so little. Moreover the daylight was big ! It was the end of the afternoon without clouds with bright sun and very good visibility, not the night.
