Title: What is up with HF - Solar Flare? Post by: W1UJR on May 08, 2005, 09:05:34 AM I noticed last night that sigs last night had a very rapid QSB and sounded quite weak.
I have heard solar flares and the "watery" sound, never heard anything like last night. Even the AM broadcast band was effected, WKBW was very hard copy. Did we have a solar flare and if so is there a quick place to check this? Anyone else notice this? Tnx, 1UJR Title: What is up with HF - Solar Flare?

Storm levels are defined as 5 and above (max of 9.

Usually that page is updated at least hurly. They do mention some effect of a CME coming our way that may have been the source of what you observed.

Post by: W1GFH on May 08, 2005, 05:08:53 PM Last night, the higher bands like 10, 15, and 20 meters were open
late - 9 and 10 PM PST. Heard ZL's and VK's vy strong. Unusual condx! Title: Re: What is up with HF - Solar Flare? Post by: Glenn K2KL on May 09, 2005, 02:14:23 PM I noticed the same thing last night Bruce. Had to double check my antenna switch!!... Just a lot of noise on 75 40 and 30 meters..

Title: What is up with HF - Solar Flare? Post by: W1UJR on May 09, 2005, 11:37:01 PM Hi Glen, AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
Yes, last night was not as bad as Saurday, but still sounded quite odd. Still not sure if it is a solar flare thing or just unusual propagation. Some said they heard DX on the high bands, did not note that, but then again I was really just tuning 40 and down. Sigs sound strapping tonight, but 160 meters seems dead here, very ood. Wonder if this a regional thing or what? |
