The day looked hopeless with not a chance of clear skies. But a small hole opened, revealing Venus on the Sun.
I had seen this sight before, in 2004 from Egypt. But my first reaction upon seeing it again, albeit briefly, was [Expletive Deleted]!!! No photos really provide the visual impression of just how enormous Venus appears on the Sun. We’re used to sunspots (and there were lots today) and some quite large. But nothing we ever see on the Sun matches the size of Venus. The eyepiece impression is of something much larger than the photos show. It’s like Moon illusion at work on the Sun.
It had been hopelessly cloudy all day in Calgary. Interpretive obligations over at the science centre (where we showed the NASA webcast from Hawaii), I hit the highway in search of a clear hole … and found one northeast of the city, one at first that seemed to be wide and stable. I stopped, looked with the filtered naked eye, then drove on seeking slightly less cloud, getting greedy! I should have stopped sooner. By the time I did stop and hurriedly set up the little 80mm refractor telescope, I had about 30 seconds for a great clean view, then switched to the camera. By the time I got it set, clouds were coming out of nowhere and thickening fast. I couldn’t shoot through the solar filter. This is a filterless shot, at 1/8000th second! Clouds provided the natural filtration. Fine! At least I got the camera focused, for a crisp view of Venus next to the clusters of sunspots, something no one alive has seen — in 2004 the Sun was virtually spotless.
So, not a view or photo under the best of conditions, but an experience I am happy to settle for. Now, I just want clear skies in Australia for November’s total solar eclipse. Please!!
