As the time of the “last” transit of Venus is perhaps ended, I would like to show all an old
but spectacular observation of a transit of Mercury I made in 1970.
My sketch shows not only a solartransit, but the planet also passed over a close bipolar
It was interesting to observ the absolute black Mercury with the umbra in the spots.
The umbra was easy seen brighter. My info on sketch is in norwegian!
This was a lucky observation, indeed!!
Location : Trondheim, Norway.
I used pen and pencil on this original sketch.
Thanks for nice comments on my sketches!!
Have a clear sky and nice time to all!
