Geophysical Alert MessageSolar-terrestrial indices for 06 September follow.
Solar flux 110 and estimated planetary A-index 5.
The estimated planetary K-index at 1200 UTC on 07 September was 4.00.No space weather storms were observed for the past 24 hours.
Space weather for the next 24 hours is predicted to be minor.
Geomagnetic storms reaching the G1 level are likely.

Space Weather
Disturbed geomagnetic conditions are continuing.
Significant solar wind dynamic pressure of 30 cm^3 is being recorded at L1, along with a marked negative Bz swing to ~ -12nT.
Solar wind speed has jumped above 500km/s. The DST (Disturbance Storm Time Index) peaked positive due to the initial compression from the CME impact, but it's now swinging negative as the ring current intensifies. Later, as the storm peaks, energy will be released via magnetic reconnection in the magnetotail, shooting accelerated electrons Earthward along field lines to trigger substorms and hopefully aurora.

🔴 Substorm expansion phase
Substorm breakup in progress — aurora is likely active now. Ground confirmation at Macquarie Island.

Space Weather
CME arrival: The first CME in a potential series has arrived overnight - somewhat earlier than predicted.
IMF Bz is strongly southward and substorms are now hitting polar regions.
HF radio will be degraded at high latitude and polar regions - aurora is possible.

🔴 Sustained southward Bz detected
Bz has been consistently southward (currently -8.5 nT). Sustained southward fields maximise geomagnetic coupling and support aurora activity.
