Depending on where you live, this G4 geomagnetic storm may completely disrupt the HF band conditions. From Spaceweather.com:
SEVERE GEOMAGNETIC STORM IN PROGRESS: A severe G4-class geomagnetic storm is in progress on June 22nd. This follows a series of rapid-fire CME strikes to Earth’s magnetic field during the past 24 hours. Magnetic fields in the wake of the latest CME are strongly coupled to Earth’s own magnetic field. This is a condition that could sustain the geomagnetic storm for many hours to come. High- and mid-latitude sky watchers should be alert for auroras tonight, especially during the hours around local midnight.
On the up side, after this is over, there may be some excellent, short-term band openings. My buddy, David Goren, also reminds us that this is a good time to keep an eye on the broadcast bands for auroral conditions.
