Something new (to me) caught my eye this morning and brought an exclamation to my lips: the three-day geomagnetic forecast for today shows Purple!! This indicates some serious geomagnetic activity! Red is not uncommon, but Purple really got my attention!<\/p>\n

The disturbance is due to an active sunspot area 31 times the size of earth! There are 3-4 CMEs (Coronal Mass Ejections) headed our way, arriving in the next day or two, which will likely make SWLing a bit difficult, if not causing at least momentary blackouts in some places.<\/p>\n

On the upside, for those amateur radio folks who like working Auroral Skip, conditions are likely to be quite interesting in the VHF and above ranges.<\/p>\n

SolarHam.net<\/a> and SpaceweatherLive.com<\/a> are both excellent sites to study solar activity, so give them a visit! 73, Robert K4PKM<\/p>\n
