This morning the Sun was in annular eclipse for a small part of the world. Parts of Canada, Greenland, as well as northern Siberia, were graced with views. At sunrise here in the midwest of the U.S. I was not able to see any of it. Instead, I went to Time and Date for live telescopic views streamed from several locations. The views were excellent from Science North, a science center located in northern Ontario in the city of Sudbury. The Sun rose with the Moon covering most of it illustrated by this screen shot.Continue reading
It was just after 6 am on 16 September. The Sun barely brightened the sky in the east. A thin haze was in the air from forest fires to the west. I live in Iowa. We have had several days of filtered light through the smoke and haze. The Sun rises and sets very orange. On this morning I hoped to photograph the thinnest crescent moon I had ever seen. It was only 24 hours before the next new moon.
I had been up since 5:30 with binoculars scanning the sky close to the horizon. At 6:07 am I spotted the thin crescent through the haze only 5˚ above the horizon. I grabbed several shots then watched as it rose and the sky brightened. Soon the Moon disappeared in the bright sky.
Evening views of Venus have been beautiful. The planet is passing us in orbit and by the end of May will be hidden in the glare of the Sun. It will emerge again in June but as a morning object.
Last evening was clear and cold, providing a perfect view of Venus. With the camera mounted on a tripod and fully zoomed, the crescent was obvious. A small telescope or steadied binoculars will work, too. Give it a try. Your evening opportunities are waning.
A solar eclipse took place on 26 Dec 2019 visible from Saudi Arabia to Guam, crossing India, Sri Lanka, and Indonesia. It took place during the night of Christmas for those of us in the U.S. I stayed up to watch it online a little before 10 pm.
The Astronomical Institute in Sri Lanka webcast the eclipse the entire duration. Their video is here. Annularity begins just before the 2 hour 5 minute mark. I selected the portion of their video showing the beginning to the end of annularity and sped it up by 4x.
I like long exposure photographs called solargraphs. Photo-sensitive paper is put inside a light-tight container. A pinhole in the container allows an image to be formed on the paper after a very long time. My first attempts were described here. If the Sun shines into the pinhole, it traces a bright line across the paper as in this day-long exposure.
Everyday the Earth moves some distance around the Sun in its orbit, shifting the position of the Sun in the sky. The Sun traces in a solargraph also shift a little each day. Our front window faces east toward sunrise. I exposed a solargraph to those sunrises with hopes of seeing the Sun’s movement toward the south over a long period of time.
