A fireball at night, as bright as a crescent moon - 6.10.2012 at 05.23 Espoo Observation number 8236

Visibility IV / V

Panu Lahtinen, Ursa (Etelä-Suomi)

After a long cloudy period, a fireball was recorded in the sky camera. This time, my program used a tuning based on Antti Kunts' idea, which records the maximum stack of pixels for the exact time in the second image (the latter image).

The streak is stored between 05.23.00,528 and 05.23.01,888 Finnish summer time, ie the visible flight time was 1.36 s.

Time is encoded in the color image in milliseconds from the start of the stack. For now, counting time is a craft, but these aren’t so terribly surprising that it would hurt.
