Another Blast Coming

Speaking of 'everlasting', wimpy Solar Cycle 24 has been showing more energy in its death throws than it ever seemed to show during its peak.








It continues to blast earth with a never-ending series of coronal hole streams leading to periods of high signal absorption (particularly on the lower frequencies) and widespread auroras.

The present rip in the Sun's surface is the same one that caused major disruptions during the last solar rotation. Geomagnetic storming and propagation disruptions are forecast to begin around the 28th, with a proviso ... these ones could be even worse than last time as the wind's polarity at present is favorable to greater coupling with the Earth's magnetosphere, sending the Earth's Bz southward (negative) into auroral producing, prop-killing conditions.

Sometimes, though not normally, these events can produce periods of enhanced low frequency propagation, especially during the hours just before the event's commencement ... the best thing to do is just continue to operate normally and not assume the worst. I've been guilty of this in the past and being caught off guard, have missed some better than usual LF propagation.

 I'll keep my fingers crossed over the next few days and think positive ... Bz-wise!
