Analyses of the Ancient Chinese Report on the Total #SolarEclipse in 709 BCE - Implications for the Contemporaneous Earth’s Rotation Speed and Solar Cycles: https://iopscience.iop.org/article/10.3847/2041-8213/ae0461 -> Humanity’s earliest datable record for a total solar eclipse allows scientists to derive accurate measurements of Earth’s ancient rotation speed and provides independent validation of solar cycle reconstruction in the 8th century BCE: https://en.nagoya-u.ac.jp/news/articles/historical-geography-helps-researchers-solve-2700-year-old-eclipse-mystery/

30 years ago #OTD I was in #India to observe a Total #SolarEclipse lasting under a minute in Neem Ka Thana, Rajasthan: my report on the whole trip to this amazing country - written originally for an English magazine - can be found at https://geocities.restorativland.org/CapeCanaveral/5599/india_95_story.html while the picture here was taken by Voyto Rušin at the same observing camp and processed by Miloslav Druckmüller: http://www.zam.fme.vutbr.cz/~druck/eclipse/Ecl1995i/0-info.htm

The partial #SolarEclipse from Dunedin, New Zealand: a screencap from 18:42 UTC. Meanwhile https://www.timeanddate.com/eclipse/in/new-zealand/dunedin?iso=20250921 is simulating the eclipse's progress live. At maximum 3/4 of the disk will be covered.

The Sun during the Partial #SolarEclipse today (local time) rising in New Zealand: https://www.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 https://skyweek.wordpress.com/2025/09/19/allgemeines-live-blog-ab-dem-19-september/#Sep21 for links to more visuals under that video - in particular the timelapse https://www.facebook.com/reel/1431275405270694

A bit after the maximum phase of the partial #SolarEclipse another feed from Dunedin, New Zealand, appeared on https://www.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 https://www.timeanddate.com/eclipse/in/new-zealand/dunedin?iso=20250921

From 18:00 UTC today (Sunday) there may be a webcast of the partial #SolarEclipse on https://www.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 https://www.facebook.com/SolarHam/posts/pfbid0LKUaGuBPo11nHtuHdfYmto1SRd1HFkrrGXVznc36AaxAfiAhHiDTAeoJwXZFnkpFl

Total #SolarEclipse triggers dawn behavior in birds: Insights from acoustic recordings and community science: https://www.science.org/doi/10.1126/science.adx3025 -> "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."
