The Sun: Our Powerhouse

Over the last year, I’ve noticed increased media stories about the sun. The news coverage has mainly focused on topics related to our star’s 11-year solar cycle. This isn’t surprising since solar activity has been escalating since December 2019 and is on a trajectory to peak in July 2025.1 That’s why we’ve witnessed a greater frequency of northern lights, flares, and sunspots.

So when I woke up today with no Seattle clouds in sight, I decided to take photos of the sun. Why not, I thought to myself. It had been six years since I last did so—and that was for the 2017 Great American Eclipse.

This morning turned out better than I expected. Indeed, the sun presented a handful of nice sunspots. For the photos below, I used a Canon 70d with a Tamron 18-400mm lens (at 400mm) set at ISO 100, f/30, with a 1/10 second exposure. I also used the solar filter I kept from the 2017 eclipse!
