Looks like IEEE has finally renamed their sustainable tech conference. Now it’s “IEEE SustainTech Expo.” Not only is it a bit clearer than the old name, but ever since Among Us came out, “SusTech” always made me giggle a bit. I doubt I was the only one.

Update: apparently I was mistaken, and SustainTech is entirely separate from SusTech, which is still going on. Looking at it a bit more, it seems that SustainTech is more of a marketing/trade show, while SusTech continues to be a technical conference.

It was hazy, and the weather forecast was partly cloudy, but the sun stayed visible and the eclipse glasses (used here for the photo) haven’t cracked!

Yellow-orange circle on a black background, with a circular chunk apparently cut out of it.

We didn’t do anything complicated this time: just took the glasses with us as we went about our morning, looking through the glasses every 15-20 minutes to see how much was covered until it reached its maximum coverage of 78% of the sun’s apparent diameter.

And at projections. Leaves are nature’s original pinhole camera!

A bunch of overlapping bright crescents of light on the ground.

A road trip like 2017 to see the full annular eclipse would have been cool, but it just wasn’t something we could do this time around, and with clear visibility, there wasn’t any need to seek higher ground like 2012.

Here’s peak coverage for this area, again viewed through eclipse glasses.

Found the eclipse glasses from 2017. Checked for scratches. Looks like they’ll be usable for Saturday’s solar eclipse!

It’ll be partial here in California, covering ~78% of the sun’s diameter. The annular shadow passes from Oregon diagonally to Texas, crosses the gulf to Yucatan, then follows Central America and crosses Brazil from west to east at its widest part.
