Horizontal lines in MetRec

I was disturbed to notice numerous horizontal lines in the video of my meteor camera (see the MetRec image). At the beginning I was afraid that this was due to the fact that the camera was powered in daylight (even with the possibility that the Sun passed through the fov!). I asked around to find […]

More Potential Hazardous Asteroids than what we thought – the Chelyabinsk event

Geminids and their mysterious parent body 3200 Phaethon

The Geminids are one of the best meteor showers of the year with numerous (ZHR~120) and bright (r~2) meteors! The parent body is an asteroid named 3200 Phaethon, which is believed to be a candidate for an extinct cometary nucleus, a mystery by itself. Moreover, during the last perihelion passage of the asteroid its magnitude increased […]
