2019 August 22 - Asteroid occultation at Hokoon

Asteroid (1114) Lorraine (mag.15.1) was predicted to occult the 12.1 mag star UCAC4-408-113298 at 14:44 UTC.
With the help of Bartholomew Tsang, we started preparing observation at about 12:30 UTC, despite a very low transparency and clouds.
Unfortunately, only a few snap shots were captured as the star was covered by clouds most of the time. The asteroid was never seen.

Telescope: 50-cm f/8 RC reflector
Camera: ASI1600MM Pro, cooled to -13C
Binning: 2x2
