On 14th November, Monday, morning, or on sunset, the full Moon was the biggest and brightest in almost 70 years. Looks much one full Moon like any other? Because the Moon's orbit is not a circle, it's an ellipse, one side of the Moon's orbit, called perigee, is 50,000 km closer to Earth than the other side, apogee. The last time we had such a close full Moon was in 26 January 1948. It happens again in 25 November, 2034.
Monday, about 2 hours away from perigee, the "supermoon" becomes full; 14% bigger and 30% brighter than lesser moons seen in the past.

after sunset on the same day was the best time in Europe.
