Induced Currents - Power system voltage irregularities possible, false alarms may be triggered on some protection devices. Spacecraft - Systems may experience surface charging; increased drag on low Earth-orbit satellites and orientation problems may occur. Navigation - Intermittent satellite navigation (GPS) problems, including loss-of-lock and increased range error may occur. Radio - HF (high frequency) radio may be intermittent. Aurora - Aurora may be seen as low as Pennsylvania to Iowa to Oregon. #------------------------------------------------- http://www.hamqsl.com/solar101vhfper.php Edited June 8, 2014 by Odourless Quote Link to comment
+Mineral2 Posted June 9, 2014 Share Posted June 9, 2014 (edited) yeah, this happened last night. Hopefully, some of you in the high latitude regions got to experience the byproduct of such a geomagnetic event: Aurora Borealis by Matthew Singer, on Flickr Edited June 9, 2014 by mineral2 Quote Link to comment
Fangamon Posted June 18, 2014 Author Share Posted June 18, 2014 Yes, sometimes with the right info you can recalculate around it... http://www.hamqsl.com/solarsun.php Quote Link to comment
