A bright ring surrounds the sun, which is blocked by an overhanging street sign.

A full 22-degree circular halo spotted today, caused by sunlight refracting through ice crystals in the thin cloud layer. (It was around 65F at ground level.)

These halos are about the same width as a 1x photo on my phone (and most point-and-shoot cameras I’ve had), so I used the wide angle mode to catch the whole thing and then crop it down. I bumped up the saturation a little, but otherwise it’s unprocessed.

A smallish lake surrounded by green plants and golden brown hills, bright blue sky above it, and a large overflow drain in front of it off to the right.

The flood control basin has been partly restored for stormwater infiltration and as habitat for native plants and migrating waterfowl, bounded by a city park on one side, baseball fields on the other, and hills all around. The city is currently expanding the basin while the water level is low.

The same lake and drain, but the plants are mostly brown and yellow, the water's a lot lower and smaller, and construction equipment is moving dirt around.

From this afternoon’s walk along the greenbelt: About as many monarch butterflies in one photo than I’ve seen in the last few years!

A lot of orange-and black butterflies on a pine branch, most of their wings closed.

There were a whole bunch of them clustered on a pine branch above the path. I wouldn’t have even seen them, but other people out walking had stopped to check them out.

I was just reading that this year’s overwintering monarch count is up to over 200,000 – a huge improvement over last year’s count of, I kid you not, 1,914. Though still not up to the millions that were regularly seen as recently as the 1990s. That article lists ways you can help the iconic species rebound, or you can follow the Xerces Society’s Monarch Call to Action.

We actually got quite a bit of rain (for Southern California, anyway) in December, and the mountains have stayed cold enough that the snow has stuck around for a few weeks!

Here’s a view of the San Gabriels in mid-December, after a big storm.

Snow-covered mountains in the distance, with partly cloudy sky above and green trees and a lamp post in the foreground.

And here’s a comparable view a week into January.

Snow-covered mountains in the distance, with blue sky above and green pine trees in the foreground.

Nowhere near as impressive as, say, the entire range being covered in 2008, but that’s a rare occurrence even in non-drought years…and we’ve had mostly warmer and drier years since then.
