“We await the arrival of the Valentine’s Day solar storm, which will be followed by some fast solar wind just behind it. This means we should enjoy some extended storm conditions over the next few days with a chance for aurora down to mid-latitudes! Meanwhile region 2699 continues to boost the solar flux for amateur radio operators, but this will only last for a few more days until the region rotates onto the Sun’s backside and out of Earth view. Learn the what kind of storm conditions to expect, when radio propagation for amateur radio and emergency responders will worsen, and why it can be hard to predict the arrival of some solar storms!”
