I'll just note here:
Thursday 17 December 2015 I happened to look up at the crescent moon. And it looked wrong. It looked like the upper point of the crescent had been shaved off. A day after this I was browsing on youtube and came to a user reporting on this supposed planet X etc. Two of his commentators had noticed the same (about the moon).
youtube username is "Separated Society". He is also seems to be predicting, or at least linking, earthquake activity in connection with comet Catalina.
Oh, and there was that big bright green meteor I saw breaking up on 29 Nov 2015!
(Not sure what to make of it all myself!)
