Strong positive polarity CH HSS sparks G2 – Moderate geomagnetic storm

Strong positive polarity CH HSS sparks G2 – Moderate geomagnetic storm

A strong positive polarity coronal hole high speed stream (CH HSS) sparked a G2 – Moderate geomagnetic storm on September 4, 2022. G1-Minor storms continued into September 5. An additional enhancement is possible by midday today due to the arrival of CME produced on September 2.
