To-night the sky is cloud covered, so no sunsets and comet pics, however, the smoke in the atmosphere is producing some really weird all over sky glows.
As I took shots of the Comet last night, the effects changed the lower the comet moved. Here are some results.
The comet was certainly less brilliant than two days ago (must be our bushfire smoke polluted skies) A report I read indicates that this comet is moving much faster than usual. See attached from an experience comet observer.
: C/2006 P1 is the fastest moving comet I've come across in my past
> seven years of comet imaging. On Jan 15 at 0000 UT its motion
> relative to the stars was 9.67 arc seconds per minute. Most comets
> are of the order of 1 to 2 arc seconds per minute at their
> brightest. I check http://scully.harvard.edu/~cgi/MPEph2.COM to get
> the relative motion before I image so I can calculate how long I can
