2024 Total Solar Eclipse

Sun's Corona During Totality

We saw the eclipse; it was awesome!

It was quite the journey. Here's the GPS track, showing major stops. This was NOT what I planned.

Route of Travel

Years ago, actually right after the 2017 eclipse, I started planning for the 2024 eclipse. I checked the historical weather maps and decided my best chance of clear skies along the path of totality would be in Texas. With about six months to go, my wife made a hotel reservation in Austin. Then I picked a couple of places near Austin as candidates to set up to watch and photograph the eclipse.

My wife took a flight to an event in Nashville the week before the eclipse, so we planned for me to pick her up there enroute to Austin. By the time I reached Nashville on April 5, the forecast predicted overcast and rain for most of Texas, but clear skies in New England, so we cancelled the reservation in Austin and headed for New England. We stopped overnight in Ithaca to visit the city where my wife went to college. Then we went to Lake Placid because that was closer to New England and it was among the few places where we were able to get a hotel room. Then on the morning of April 8, the day of the eclipse, I checked the weather forecast one last time, and it looked like we needed to get beyond Burlington to the east for the best chance of clear skies. New Hampshire and Maine would have been better, but it's hard to travel east-bound in New England because there just aren't a lot of highways, so we went to Newport in Vermont. There was snow on the ground in Lake Placid and in northern Vermont.

When we arrived in Newport I chose Gardner Memorial Park as the place to watch the show. I picked a spot by the lake shore, set the cameras up, and waited under clear blue skies.

Camera Setup

Shortly Before Totality

Of course it didn’t stay completely clear. A thin cloud layer approached, and during totality we watched the eclipse through that thin layer. As it got dim, we could easily see Jupiter and Venus. Despite the clouds, we had a great look at the sun as it got cold, then dim, and during the final seconds before totality we saw the moon move to blot the sun out. We saw the corona and an enormous prominence with our naked eyes. I had one camera on a script controlled by a computer that snapped away. I had another camera that I shot manually, on a tripod, not looking at the camera at all, just using a remote trigger.

After totality, most people left. We waited for the end of the partial phase. After the eclipse ended, we checked traffic on the maps on our phones. Predictably, it was awful. I chose to avoid the interstate highway and instead took state highways to Burlington. There, we ran into traffic and slow going all the way to Glens Falls. When we finally got onto Interstate 87, traffic was very heavy but moving, and finally we stopped for the night at a hotel near the Albany airport. We returned home to Virginia the next day.

Here are a few shots of the eclipse.

Partial Phase with Sunspots
The shot above shows some large sunspots during the first partial phase.
Beginning of Totality
The shot above shows the beginning of totality, with prominences near the top of the photo, and just a hint of the large prominence at the bottom. The moon moved from bottom to top, with the top being the last part of the photosphere to be obscured, hence the prominences and glow at the top.

End of Totality
As totality ended, the moon moved to expose the bottom of the sun, showing some enormous prominences. We could see these with the naked eye. For reference, the large prominence on the lower left of the photo was several times the size of the Earth!

Baily's Beads
As the photosphere became visible, I got some fleeting Baily's beads.

Here’s my first/only attempt at a composite in Photoshop.

So it was a lot of driving for only about three minutes of totality. And it was just as good as I remember from 2017. The next one in the US is a lot of years away. Maybe we’ll try for one in Australia.

Solar Eclipse Tomorrow!

The weather isn’t cooperating; I’ve had to make a drastic change to my solar eclipse viewing plan.

I planned to watch the eclipse in Texas. I got a hotel reservation. My wife had an event in Nashville. I planned to pick her up on my way from Virginia to Texas. But the weather didn’t allow that. By the time I got to Nashville, the forecast for nearly all of Texas along the path of totality was cloudy and possible rain.

I reached Nashville on Friday. The eclipse is on Monday. I checked forecasts for other locations on the path of totality. There were several possible openings, but New England was looking very clear. We cancelled the hotel reservation in Austin and made a reservation in Ithaca, NY, and Lake Placid, NY. We picked Ithaca because it’s reachable in a (long) day of driving (and my wife went to college there). We picked Lake Placid to get us closer to New England. We stayed in Ithaca on Saturday night, and now we’re in Lake Placid for Sunday night. Of course the weather isn’t cooperating again. I was hoping to go to Burlington tomorrow morning, but now it looks likely that clouds will approach by 2PM, just as the eclipse is starting. So now the plan is to go to Newport in Vermont.
