☀️ Sometimes, the Sun tries to erupt — and fails.

Observations from multiple spacecraft captured a solar eruption as it rose, only to be stopped by the magnetic field above it.

What can a failed eruption teach us about the Sun and space weather?

Space Weather

A G1 (minor) geomagnetic storm is continuing. A G2 watch is in effect for tomorrow (09 Sept).

A minor electron storm reached L1 at 13h UT. Electron flux rates at GOES (in geostationary orbit) may be peaking around now (18h UT), but flux rates at L1 are increasing again so this is one to watch.

The sun remains very active with some flare players rotating Earthwards in the coming days. We may also be under the influence of a coronal hole which is currently facing Earthwards, so expect further radio blackout, HF band degradation and good chances for aurora at high latitudes.

Space Weather

The geomagnetic storm strength reached G1 (minor) level at 07h30 UT this morning.

Further bursts of substorm activity will continue as this storm progresses, giving further opportunities to see aurora at the higher latitudes.

Space Weather: Geomagnetic Storm Update

Geomagnetic activity is continuing to build as a number of CMEs reach Earth. Aurora has been seen at high latitudes.

The 1-minute Kp level is currently below G1 level (Kp4) but it's likely to exceed that soon. The DST (Disturbance Storm Time index) is falling quickly and is now at -47nT, showing that the ring current is charging up.

Amateur radio operators at high latitudes have reported auroral radio contacts over Scandinavia.
