Northern HemisphereIan Morison tells us what we can see in the Northern Hemisphere night sky during November 2020.Highlights of the MonthEarly November - still a good time to view Mars. This is still a great month to observe Mars which had its closest approach to Earth on October the 6th when it will lay 39 million miles from Earth and reached opposition on the 13th so the highest in the south around late evening. Wonderfully, at this opposition, Mars is far higher in the sky than at recent
