It was a very quiet night at my station in Texas. If I had not already checked other receivers and antennas I might have assumed something was wrong since there were numerous lightning-rich storms across the US and I wasn’t hearing them. As I suggested in the ON4KST chat/logger, perhaps not hearing the noise that should have been audible was a commentary on how propagation was going to be through the session.
In reality domestic propagation was not that poor from my perspective. Some higher latitude signal reports were down and received stations continue to be few and far between but there were still numerous CW and near-CW levels reported during the session. Even a few of the higher latitude guys like new transmitting station Jeff, VE3EFF, noted reasonable conditions at low power as reported in the following details from Phil, VE3CIQ:
As so often happens I guess it just depends on where you are located and when you are QRV at any given time. That keeps things interesting.
Geomagnetic storms peaked at G3 levels with Kp-indices of 7 and solar wind exceeding 600 km/s. The Bz is pointing strongly to the South and DST reports suggest very poor conditions. I suspect the electron reservoirs will be full after this event for some time to come.
John, VE7BDQ, reported at 0619z that Larry, W7IUV / WH2XGP, was detected at +5 dB S/N at this station with strong Arctic flutter. This may be the first time I have ever heard anyone report flutter on 630-meters signals. If this should happen again, it would be great if someone could make a recording.
Ken, K5DNL / WG2XXM, reported a quiet session until 0400z when his noise level increased. Ken reports that he decoded three WSPR stations and was decoded by 27 unique stations. He also indicated that he does not feel like his receive capabilities are up to par after his recent lightning strike but also suggests that it may just be band conditions. I concur on the latter as my observations just 200-miles away suggest profoundly disturbed conditions and not indicative of a real receiver problem. Time will clarify this situation, however.
Neil, W0YSE/7 / WG2XSV, reports that he decoded WH2XCR once while being decoded by Merv twice during the session. It seems that the path to and from Hawaii has been poor, even for Neil. In my case, I have had no reports to or from Merv in this session once again. Jim, W5EST, suggests that it may just be a spotlight event for the stations being reported under these conditions and spotlights are evidently few and far between at the moment. Neil submitted the follow comments and statistics for his session:
Regional and continental WSPR breakdowns follow:
There were no WSPR reports from the trans-Atlantic or trans-African paths. UA0SNV was present from Asiatic Russia but no reports have been submitted from his station for this session.
Eden, ZF1EJ, reported WG2XXM and WG2XIQ during this session.
Laurence, KL7L / WE2XPQ, notes that in spite of G2/G3 storm levels, noise levels at VLF are normal as the blood-red auroral oval churns. Laurence transmitted during the session, sharing two-way reports with WH2XCR.
Merv, K9FD/KH6 / WH2XCR, reports that he has been QRV over the past few sessions where paths that have historically been strong are now seriously degraded. Merv notes that an impending terrestrial weather system may help improve his path to Japan but with the current geomagnetic conditions that does not seem likely. John, VK2XGJ, reports very poor conditions in Australia as terrestrial and geomagnetic storms have seriously degraded any real chance of WSPR decodes during this session. VK4YB was reported by Merv during but it was only a one-way report, which has been quite rare since Roger became active.
Jim, W5EST, is taking today off and will return with his commentaries and discussions tomorrow.
