Geomagnetic activity started off quiet but increased to storm levels as the session progressed. Solar wind exceeded 600 km/s through much of this session and the Bz component fluctuated from +/- 10 nT with much of the session in negative territory in North America. Doug, K4LY / WH2XZO, reported that he had a very strong night, receiving reports from 35 unique stations, including VE7SL and several W7 stations. Curiously, after 0700z the reports from the Northwest stopped. I noticed the same here and it may have marked the shift that resulted from the change in geomagnetic conditions. Similarly, John, WA3ETD / WG2XKA, reported a strong high latitude transcontinental path to the Pacifc Northwest but did not report the fade seen here and at Doug’s station.
The Kyoto DST showed a negative progression through the session. In recent sessions the flatness of the band has been noted and seems to correspond to periods of stability of the magnetic field, which seems counter-intuitive. Perhaps this is yet another sign that you need a “little something” to get activity moving, even if there are lasting negative consequences to propagation in the long term (“do something even if its the wrong thing!” idea). It may be that even though WE2XPQ was reported in Japan today, propagation may be terrible in Alaska for the next week because of the additional “baggage” accompanying the enhancement.
THIS SECTION CONTAINS CORRECTIONS SUPPLIED BY JIM, W5EST, 11Dec2015: Paul, W0RW / WA2XRM, operated QRSS120 from his station in Colorado through the afternoon until about 0030z when he had to QRT because he did not want to leave the long dot transmissions running while not directly watching the system. He switched to QRSS30 at 0400z. Jim, W5EST, reports that Paul’s QRSS120 signal started to be visible around Paul’s sunset in Colorado but there was no copy during the daylight hours. Jim also states that as sunset arrived, Paul’s QRSS120 remained visible until he QRT’ed.
This screen shot of Paul’s QRSS30 was taken this morning from Larry’s grabber, W7IUV / WH2XGP, located in Washington state.
Paul received strong reports from Garry, K3SIW, in Illinois with generally poor reports from John, VE7BDQ, in British Columbia.
This morning’s CW session yielded a nice QSO with Eric, NO3M / WG2XJM. Its been since before Thanksgiving that we had a chance to catch up on the air. QSB was very active, however, and several exchanges were plagued with peaks of his signal while mine exhibited fading and visa versa. The band was not terribly stable through the pre-sunrise period.
WSPR participation was high with 84 MF WSPR stations reported on the WSPRnet activity page during the North American evening. N0UR was a new station observed through this session. Jim’s software was reporting that he was potentially listening on the old frequency of 503.9 kHz and he had not reported any stations during this session so I sent him an email with the new frequencies. It sounds like he will be back listening again. Welcome aboard Jim!
The regional and continental WSPR breakdown follows:
Trans-Atlantic reports were in short supply and no North American station was reported in Europe through this session.
EA8BVP was active through the session, supply reports to a few stations in Europe:
The trans-African path to Reunion Island was once again represented by DK7FC and EA5DOM:
In the Caribbean, Eden, ZF1EJ, was alone for this session. His log, however, was well represented with reports for stations in the US:
In Alaska, Laurence, KL7L / WE2XPQ, had a smashing session, with a report from JA1NQI-2. He also appears to be hearing pretty well. As he was operating two independent systems for transmit and receive, there is a map for each:
Merv, K9FD/KH6 / WH2XCR, had a strong night with stations on the North American mainland, hearing and being heard by stations like WG2XJM, and a single reception report of VK3ELV. UPDATE: John, VK2XGJ, had a late report that did not upload properly and a screen capture has been appended with his single report of Merv’s signal.
Phil, VK3ELV, was additionally reported by JA1NQI-2 during this session:
The only other notable item that I have is that Al, K2BLA / WI2XBV, e-mailed a bit ago to say that his grant was approved this morning and he hopes to be QRV tonight with WSPR and hopefully that means a CW QSO’s will follow in short order. Welcome aboard, Al!
