  1. 🟡 CME update: WSA-ENLIL model confirms Earth arrival

    Fast CME from filament eruption (1323 km/s)
    Estimated arrival: 2026-09-06 04:00 AEST (~66h from now) (glancing blow).

    Watch for Bz turning southward at impact — that's the aurora trigger. Track live → lumina.observer/events

  2. 🔴 Sustained southward Bz detected

    Bz has been consistently southward (currently -6.3 nT). Sustained southward fields maximise geomagnetic coupling and support aurora activity.

  3. 🔴 Extreme geomagnetic variability

    Extreme swings in space weather conditions detected — auroral activity may surge or collapse rapidly.

  8. "G3 Watch for 4-5 June UTC Days" by NOAA Space Weather Prediction Center SWPC - A solar flare, more precisely a Coronal Mass Ejection (CME), may cause aurora at geomagnetic storm level G3 on Earth during UTC days June 4-5. G3 means expected Kp=7, with #AuroraBorealis down to US Midwest & northern Europe and #AuroraAustralis to South Island, New Zealand and Tasmania & Victoria, Australia. The forecast is short: #aurora may end before your sunset. spaceweather.gov/news/update-g #astronomy

  9. sws.bom.gov.au/Geophysical/1/3 🤔 It was red earlier... I am stuck here because the clouds were kind and the Dwarfs are running in the front yard.

    Maybe down at the beach we might get a shot if the aurora makes an appearance.

  10. A lot more light in the raw files! Fortunately I know an actual photographer who can help me process this into something that looks better.
