As happens quite often with us weather will intervene on Sunday — Monday when it comes to viewing Christmas Comet, 46P/Wirtanen. Yes, December 16 & December 17 are when it is closest to Earth. But, that does NOT mean that it will not be there on Tuesday or Wednesday. It will, albeit a bit further out and hence even fainter. So, binoculars would be a good idea.
So, do not despair. All is not lost. OK?
Enjoy. Happy Holidays.
