I mistakenly put the fisheye camera in its mount 90º off, so up and down in the image is east-west. I’ll fix it eventually, but it does have the kind of cool effect that the Keogram, which is a vertical slice through the center of each image throughout the night, kind of “follows” the moon as it moves across the sky. Gives it a lighthouse effect. And that’s the most positive thing I will ever say about the moon, which specializes in messing up my photos.

Searchlight sunset in the second image! These four photos taken a minute apart show the sun setting tonight behind the southern slope of @MtDavidson_SF . In the upper-right shot, the sun shines back through a stand of trees, like an orange searchlight. Live shots from this camera at https://paulclanon.com/cloud_cam

Still tracking the future site of recurrent nova T Coronae Borealis, a binary system that's not visible without a telescope now, but one of the two stars is expected to go nova soon (the last time was in 1946; before that, 1866) and when that happens it'll be as bright as the brightest stars in this shot. This is a 45-second exposure, during which a Delta flight from Seattle to San Jose was in its descent over San Francisco. The blueish tint throughout is from moonlight.

Two views of the future site of recurrent nova T Coronae Borealis last night from my roof on @MtDavidson_SF . The star (it's actually a binary system) is too faint to see without a telescope, but it's known to be a "recurrent nova", and is expected to go off again soon (sorta-maybe-probably between now and September) and be naked-eye visible for a few days before fading back to obscurity for another 78-ish years. These cameras' current views and constructed results (timelapses, star-trail images, etc.) are always up at https://paulclanon.com

Checking in on the future site of recurrent nova T Coronae Borealis, expected to go from its current obscure, not-visible-to-the-naked-eye status suddenly to being naked-eye visible for a few days or a week, probably-maybe between now and September. This binary system last went nova in 1946, and its behavior now when viewed by powerful telescopes across the spectrum of light wavelengths is strikingly similar to its behavior then, hence the prediction. Two of my cameras see it every clear night right now; a bonus last night was the SF Pride laser rainbow flag cutting across @MtDavidson_SF on its way out to sea.

Last night above @MtDavidson_SF in San Francisco American Airlines flight 1711 to Dallas-Fort Worth checks on the future site of recurrent nova T Coronae Borealis (circled), expected anytime between now and September. 45-second exposure, which is what makes the plane's path look like a light-show.

An unusually interesting day-sky in San Francisco today. Usually this time of year clouds would be an impenetrable gray murk of marine layer and fog, but today the clouds were singing and dancing up there. This is a 10X13 tiling of photos taken by one of the fixed cameras on my roof on @MtDavidson_SF between 6am and 3pm. About 4 minutes between photos. Cameras at paulclanon.com .

A spectacular meteor over San Francisco early this morning, caught by two of the cameras on my roof in 30-second exposures. For more from these cameras: https://paulclanon.com/cloud_cam and https://paulclanon.com/allsky
