Total #SolarEclipse triggers dawn behavior in birds: Insights from acoustic recordings and community science: science.org/doi/10.1126/scienc -> "Compiling more than 10,000 community observations and artificial intelligence analyses of nearly 100,000 vocalizations, we found that bird behavior was substantially affected by these few minutes of unexpected afternoon darkness. More than half of wild bird species changed their biological rhythms, with many producing a dawn chorus in the aftermath of the eclipse. This natural experiment underscores the power of light in structuring animal behavior: Even when 'night' lasts for just 4 minutes, robust behavioral changes ensue." -> "Variation in species response also informs us about variation in sensitivity to light, with implications for the impacts of artificial light."

The Sun during the Partial #SolarEclipse today (local time) rising in New Zealand: youtube.com/watch?v=Y6qgB_3nIIQ -> "You can see lots of green and blue flashes on the edge of the moon, as well as various other atmospheric phenomena." See also skyweek.wordpress.com/2025/09/ for links to more visuals under that video - in particular the timelapse facebook.com/reel/143127540527

The partial #SolarEclipse from Dunedin, New Zealand: a screencap from 18:42 UTC. Meanwhile timeanddate.com/eclipse/in/new is simulating the eclipse's progress live. At maximum 3/4 of the disk will be covered.

A bit after the maximum phase of the partial #SolarEclipse another feed from Dunedin, New Zealand, appeared on youtube.com/watch?v=frOkEPoP1C4 - they have four cameras running but suffered from connectivity issues.

Sadly the live feed from New Zealand of the partial #SolarEclipse was lost a while ago (with the image frozen, now removed) - here is what the eclipse would have looked like moments ago at maximum phase in Dunedin, from the real-time simulation timeanddate.com/eclipse/in/new

From 18:00 UTC today (Sunday) there may be a webcast of the partial #SolarEclipse on youtube.com/watch?v=frOkEPoP1C4 - if the weather in New Zealand cooperates. No plan B apparently ...

The webcast #SolarEclipse is underway and has a feed from Dunedin, New Zealand where the partially eclipsed Sun will rise in a few minutes - meanwhile here is the eclipse already underway as seen by SUVI on the geostationary weather satellite GOES-19 at 17 nm wavelength, from facebook.com/SolarHam/posts/pf
