How the #Perseids 2025 performed: global activity profiles from two video networks and radio echos place a single pretty pronounced peak around 23:00 and 18:00 UTC on 12 August, respectively, perhaps probing different dust populations. Visual data (not shown) have the peak around 21:00 UTC but nearly level activity until 2:00 UTC on 13 August: see https://skyweek.wordpress.com/2025/08/04/allgemeines-live-blog-ab-dem-4-august-2025/#Aug16 for the sources and more numbers.

Anyone who follows me has probably gathered that I've become a fan of Discourse after running a few Discourse instances. They are currently requesting feedback.
I was pleased to see that they used a survey vendor that appears to have meaningful a11y — I didn't look for aria labels so I won't speak to that, but what I did notice is that there is explicitly-labeled support for keyboard-only interaction on every page, and I really appreciated that thoughtfulness.

50 years ago today, at 16:09 UTC on 17 July 1975, the Apollo-Soyuz Test Project culminated in the first docking of the spacecraft - but afterwards an interesting experiment took place: after they separated again Apollo (the final one; no number) occulted the Sun from the point of view of Soyuz 19. Images obtained show mostly outgassing from Apollo forward-scattering light from the hidden Sun but allegedly there is also some outer corona in the images of which #eclipse experiment was described in the mission press kit https://www.nasa.gov/wp-content/uploads/static/history/astp/documents/astp press kit (us).pdf on PDF pages 37-39 and the outcome is discussed in the didactical NASA brochure https://ntrs.nasa.gov/api/citations/19780019206/downloads/19780019206.pdf on PDF pages 20-27; there is apparently also a more technical paper in a mission science report but I couldn't find that one online.
