Total Eclipse 2024

On April 9, 2024 - Photography, Uncategorized

Some of you may have heard we had a total eclipse yesterday. I ventured up Owl’s Head in the Groton State Forest in Groton, Vermont to have a look. I was joined by 75 of my closest friends. The crowd was very friendly and I met lots of great people.

I was using my 400mm with a 1.4x extender with Thousand Oaks film solar filter. I used the timer on my phone to time the images, aiming for five minutes between shots. There is a fair bit of variation. I seriously misunderestimated how long it would take me to get the solar filter off and require the sun and failed to capture totality. I’ll be kicking myself for years…..

As predicted, traffic was horrible, I had to follow this guy all the way from Wells River to Groton.

Onset was about 2:15 p.m. I was surprised at how clearly we can see two sunspots with lens with such a modest magnification.

Sunspots are caused by intense magnetic flux (flowing liquid) pushing up from the Sun’s interior. This movement of flux creates magnetic fields roughly 2,500 times stronger than the Earth’s and interferes with the nominal convection on the Sun’s surface. This causes cooler areas – only about 7,000° F (normal is roughly 10,000°F). This causes the dark spots we can see on the Sun’s surface. Typical sunspots are roughly the size of the Earth.

I’ve got a great deal on some eclipse glasses for you……

Hope to see you all at one of the 11,897 eclipses we’ll have before 3,000 CE.

Loons should appear sometime in the next week. I’ll be checking regularly.
