Reports Report 4167ak (Event 4167-2017)

Name Jean-Francois G
Experience Level 4/5
Remarks Conditions were not ideal for me as I saw the fireball just when I stepped out of the house to check on my telescope in the backyard. I'm confident that my Azimuth estimate is correct to within 15 degrees (I should have been more careful in recording the azimuth) and my altitude estimate is probably correct to within 10 degrees.
