Fireball report

Reports Report 1143cn (Event 1143-2013)

Observer
Name	Kevin L
Experience Level	3/5
Remarks	Great Report App. I will endeavor to be more scientific the next time I see a bolide. I would rate brightness as (-6) +/- 1. It seemed about 2 magnitudes brighter than Venus (mag. 3.9 that night), but I wasn't in a data-collection mode as much as simple wonderment.

Concurrent Sound
Observation	No
Remarks	-

Delayed Sound
Observation	Yes
Remarks	Even though I was still marveling with my wife about our unexpected bonus of the meteor, and I was not actively listening for something, on the order of about TEN seconds later I heard a brief (one second or two) sound (a distant crackling rumble) that could have been made by fireworks—and alas, there were some being used that evening a few miles away, so confounding is definitely a possibility—but I am reluctant to rule out completely an electrophonic phenomenon since the sound was so reminiscent of the one time in my life I heard it before in connection with a bolide. There were no successive booms.
