Title: Aurora Friday morning? Post by: WA3VJB on February 15, 2013, 04:41:59 AM Pre-sunrise condx on 3885Kc sounded a lot like some aurora floating around.
Anyone seeing some Northern Lights? WØXV in Mississippi on a BC610 and WB4WCJ in Hardeeville SC on a modified amp he just got going. Title: Re: Aurora Friday morning? Post by: Pete, WA2CWA on February 15, 2013, 12:03:47 PM That doesn't sound like auroral conditions. Most likely it's some D and E layer anomalies. The solar flux is estimated to only be around 100 over the next several days. You can always check here to see if some aurora is creeping down close to the U. S.:
(http://www.swpc.noaa.gov/pmap/gif/pmapN.gif) I was listening around 1 AM on 75 and heard several west coast AM QSO's. Signals weren't bad and the noise floor seemed to be lower then what I have been hearing on previous early mornings. Title: Re: Aurora Friday morning? Post by: WA3VJB on February 16, 2013, 11:52:16 AM Yeah it doesn't have the characteristic "watery" phase distortion, now that I listen on better speakers. And, since both those stations are south of me, aurora was even less likely to affect propagation to here than had the stations been to the north.
Second guess was that it might have been that Russian meteor on its way. Title: Re: Aurora Friday morning?

Meteors/asteroids leave ionized tails, and given the closeness of the travel, it's possible that lots of ionized particles dropped into the ionosphere and upset the typical balance of stuff at that time of the morning. I guess we'll have to see if any of the propagation "experts" have anything to say about it. I did notice I had a bit of a glow when I got up that morning. |
