Telescopic comet Schwassmann-Wachmann - 24.9.2017 at 21.13 - 24.9.2017 at 21.32 Orimattila, Artjärvi, Tähtikallio Observation number 67810

Visibility III / V


29P / Schwassmann-Wachmann 1 Filmed on a DS weekend on Sunday. We have photographed the comet before with information http://www.taivaanvahti.fi/observations/show/66401. eruption! Sometimes a comet has also been suspected of forming antimatter due to eruptions. There is ordinary material according to current knowledge :), good like this. I measured the image as a location for the core 21h06m02.1s -14d45'59.3 "core 15.7mag, Horizon 21h06m02.15s -14d46'00.6" 14.59mag and the measured total brightness 14.0mag. For the total measurement, I used the largest measuring circle 20 allowed by MaximDL. The picture also shows the galaxy 2MASX J21055705-1450238 r.15.7mag and the dim LEDA 920382 next to the comet.
