This was a very good session with very quiet, stable geomagnetic conditions through the evening in North America. It was so good, in fact, that I had forgotten that during the early evening, at least in Texas, there was quite a bit of noise from storms in the Gulf of Mexico. While Gulf storms typically impact the noise floor across North America, these did not seem to have a long-term impact.
The geomagnetic field was very quiet with a Kp less then or equal to 1. Solar wind averaged 350 km/s and the Bz was pointing very slightly to the south in the early evening, turning north by the late evening. Protons were elevated during the early evening, peaking near 21 protons per cubic centimeter but decreasing to 4 or 5 at the time of this report development.
The band was quite strong early here in Texas. Reports were yielded through the day from stations in the Midwest and much like yesterday, WG2XIQ yielded a one hour pre-sunset signal peak with reports at WG2XJM. The peak was not as pronounced as the previous session but early reports at WG2XKA suggest that the “sweet spot” was further north. Ken, SWL/EN61, in Indiana also noted early reports from WH2XGP in Washington state at 0123z.
John, WA3ETD / WG2XKA, reported excellent domestic conditions with high activity and in excess of 1000 spots through the session for his station with some transmission cycles yielding 25+ reports. He also notes that the paths to the Pacific Northwest and west coast were open and John achieved his second night of propagation to WH2XCR in Hawaii, a distance of 7945 km. VE3OT’s ‘MP’ QRSS beacon was also quite loud in Vermont. At 0500z, John redirected his WSPR data to the alternate system after some evening outages on WSPRnet. The alternate system is now forwarding content to WSPRnet when WSPRNet is functional.
Doug, K4LY / WH2XZO, reported an even better session to the north west than the previous session, with nine decodes from VE7BDQ and five from VA7MM.
WSPR activity was very high through the session. 77 MF WSPR stations were observed at 0330z but that number was likely much higher. The only new station observed through the session in North America was WZ9B. There was a significant amount of band map pollution this morning from stations not being careful with their band selections.
Regional and continental WSPR breakdowns follow:
There were no reports on the trans-African path. UA0SNV was present from Asiatic Russia but no reports were found in the WSPRnet database.
VE1HF provided the lone trans-Atlantic report from the session for EA5DOM.
EA8BVP provided reports from the Canary Islands for EA5DOM and DK7FC.
Halldor, TF3HZ, had a very strong session from Iceland.
Eden, ZF1EJ, had a full compliment of reports, with best DX at VE7BDQ in British Columbia in spite of Gulf storms.
Laurence, KL7L / WE2XPQ, had a very strong session, with reports at WB0VAK in Minnesota, which is a path that passes through the auroral oval and also hearing WG2XIQ after many weeks of no report. Laurence indicates that a noise source that normally competes with other signals was missing during this session. Reports from WH2XCR in Hawaii were also numerous. KL7L was designated for receive-only through the session.
In the Pacific, Merv, K9FD/KH6 / WH2XCR, had another session of no Japanese reports and there were no reports from Australia as this report was developed. Nevertheless, the session was quite strong for Merv, hearing WG2XKA in Vermont as well as reports from WH2XRR in Maryland. There were no reports from ZF1EJ or WH2XZO, both of which may have experienced difficulties from Gulf storm noise.
Additional reports, statistics, comments and information:
Jim, W5EST, offers the following session profile for John, VE7BDQ:
“5 watt VE7BDQ had an excellent night, best in 2 weeks!
On the SE heading VE7BDQ-zf1ej, notice the coincidence of some spots and peaks in many directions at similar times in the Table later below.
0730z xiq zf1ej; 0840z xiq w5est zf1ej; 1100z xiq w5est.
Note unshared spots only received on that SE heading at:
0750z zf1ej; 0940z xzo; 0920z w5est.
These spots were oddly not received at xiq and xxm, who had larger numbers of receptions.
This suggests propagation was spotlighting somewhat.
What were the propagation types on the VE7BDQ-zf1ej heading? If multihop, then possibly
1&2-Ehop & 1-Fhop to xiq & xxm,
2-Ehop & 1-Fhop to xzo & w5est, and
2-E/F hop to zf1ej.”
As mentioned earlier, the forwarding module for the alternative WSPR reporting system has been implemented and appears to be working well. It was mentioned last night in the ON4KST chat/logger that a recovery process for forwarding would be nice so that spots rejected by WSPRnet due to an outage could be retried. Many operators either disregard miss spots or have to manually upload the datafile. I hope to verify that all platforms properly interface with this system tonight, if time allows. The programmer was developing a series of instructions for redirecting WSPR traffic and I hope to get an update on that process tonight as well. There may be a few items that need to be addressed with respect to the raw data rendering on the alternate site, but if the previous issues are resolved, this system my be just about ready to open as an entry point for WSPR data. That’s exciting and hopefully having some redundancy will help the quality of the system over all.
