On the 11th day of the 11th month, it was 11 degrees in my yard as I prepared to witness the Transit of Mercury. The forecast said it might be cloudy until 10 a.m. but by 8:00 there were only scattered clouds interfering occasionally. In the warmth of August 2017, I got a few images of the total solar eclipse through my telescope with the old Canon S45 camera attached. Today it was just too cold to fiddle with that setup, which is very hard to aim and focus. I gave up on that and just used my DSLR with 400mm lens. (Everything is protected by appropriate solar filters, of course.) I also set up my little Coronado solar telescope, but photography through that is impossible so that was for visual observing only.

I could not see the planet through my camera, but on the solar scope I was able to make out a little dot near the center of the sun. The apparent size of Mercury is much smaller than Venus, but we won't see another Venus transit until 2117. So this is what we have today. Unlike the total eclipse, which was rather exciting, this really doesn't get the adrenaline pumping, but it is a somewhat rare event involving another world. The next such transit is in 2032.

Next celestial events are an annular "Ring of Fire" eclipse Oct. 14, 2023 (I plan to be in Albuquerque) and a total eclipse Apr. 8, 2024 (I probably will be near Austin, TX). Previous celestial events:
