A very bright comet visible to the naked eye (easier with binoculars ) just after sunset.
My friend found this bright comet fairly quickly with the binoculars.

Here it is soon to disappear behind the Santa Cruz mountains.

This comet is also visible in the early morning before sunrise.

Here is a website describing the comet and a Finder maps.

Applied a Black Pen in Nikon Capture to the sky to help the contrast and to bring out the tail.
So the weird colors.
