Spaceweather.com reports a strong geomagnetic storm is in progress as Earth passes through a region of south-pointing magnetism in the solar wind. The storm has generated auroral displays as far south as Kansas in the US. The NOAA Space Weather Prediction Center indicates the storm is a G3 level event. WWV announced at 0900 UTC, “Geomagnetic storms reaching the G3 level are likely” over the next 24 hours. NOAA says that in a G3 level storm, HF radio may be intermittent. Calculated band conditions reported on the DX Summit site indicate “poor” conditions on 80 through 10 meters. WWV reported the estimated planetary K index at 0900 UTC was 5 (the 0600 UTC figure was 7). […] A coronal mass ejection (CME) is expected to deliver a glancing blow to Earth’s magnetic field late on June 30 or early on July 1.
