My weather sky cam recorder the fireball on one frame. It faces to west and uploads a frame to the idokep.hu server website in every 10 second. The time stamp on the image is generated by the idokep.hu server after upload. I checked the time lapse video of December 31 after I heard that there was a fireball around 16:25 CET. The video is here: http://camvid.idokep.hu/zolkabolka/zolkabolka-2017-12-31.webm (at 3:56)Nothing is visible on the frame taken 10 sec before and after. The uploaded frame is cut from that video.
