3122 Florence - 12.9.2017 at 00.09 - 12.9.2017 at 03.12 Varkaus, Härkämäki Observation number 66951

Visibility III / V

Ville Puoskari, Veli-Pekka Hentunen, Warkauden Kassiopeia

Florence asteroid light curve photographed from Härkämäki. Also included is exactly one hour of asteroid motion in the sky (01.00 - 02.00) combined into a maximum stack.

The cloud board broke that light curve for a moment, luckily no more of them came up, even though every now and then something haunted something on the horizon. Eventually, the filming ended with fog and clouds rising to Härkämäki in an instant.

VP Hentunen treated the data as a light curve, my own programs did not make any sense from a fast-moving object.
