Mercury Transit 2019 - 4K - YouTube  Nov. 11, 2019
Nov. 11, 2019:  We tried to observe the mercury transit from sunrise through the end of transit; around 7 a.m. - around 12:05 p.m.  Until around 10 a.m. it was cloudy, but we were lucky to have had clear skies after around 10 a.m. So we were able to see the transit in Lake Elmo, Minnesota, although it was very cold and windy. Temp: 18 degrees F ( -7.8 degrees C) and Wind: NNW 19 mph*  Now we know mercury is very tiny compared to the sun. It took a long time to locate mercury with our telephoto lens 400 mm (viewer 5x and 10x).
The next mercury transit** will happen on Nov. 13, 2032.
