Title: Solar WX, For What It's Worth Post by: Todd, KA1KAQ on October 02, 2013, 10:04:08 AM Received this morning:
Subject: ALERT: Geomagnetic K-index of 6 (G2) Issue Time: 2013 Oct 02 0458 UTC ALERT: Geomagnetic K-index of 6 Threshold Reached: 2013 Oct 02 0454 UTC Synoptic Period: 0300-0600 UTC Active Warning: Yes NOAA Scale: G2 - Moderate NOAA Space Weather Scale descriptions can be found at www.swpc.noaa.gov/NOAAscales<http://www.swpc.noaa.gov/NOAAscales> Potential Impacts: Area of impact primarily poleward of 55 degrees Geomagnetic Latitude. Induced Currents - Power grid fluctuations can occur. High-latitude power systems may experience voltage alarms. Spacecraft - Satellite orientation irregularities may occur; increased drag on low Earth-orbit satellites is possible. Radio - HF (high frequency) radio propagation can fade at higher latitudes. Aurora - Aurora may be seen as low as New York to Wisconsin to Washington state.

Thanks Pete. I sure used to enjoy the aurora back in my 3YPi days in N. pa. Whole family propped up on a ditch embankment watched a spectacular one a couple of solar cycles ago. Reds and greens, some straight over head.

I think the expected rays hitting the earths atmospher weren't as strong or as much as the predictors thot ......Maybe tommorow Title: Re: Solar WX, For What It's Worth Post by: Pete, WA2CWA on October 03, 2013, 11:49:31 PM The auroral oval that was linked by pete is not that strong....No reds in the picture and the oval certainly doesn't extend down into the lower 48....I just checked the latest oval...not much stronger... the bands seemed a little stronger today....But not a lot...weird condx..
