This session was better or worse depending on what you are looking for.  Domestic openings were definitely much better, perhaps returning to normal after the most recent geomagnetic event while trans-Atlantic and some of the trans-Pacific openings, particularly to Asia, were clearly impacted.  Noise in North America was not too much of a problem but here in Texas storms after dark meant increased precipitation static and the occasional lightning flash.  Ken, SWL/EN61, located in Indiana reported a pulsing type QRN during the evening that elevated his noise floor.  My elevated noise floor that was reported in previous sessions was not observed last night.

Geomagnetic conditions are starting to exhibit signs of improvement although additional unsettled levels are possible through the next 24-hours.  The Bz continues at variable levels near the centerline and solar wind velocities continue above 600 km/s.  DST values are not nearly as negative as in the previous session and the trend is toward the centerline.




Trans-Atlantic openings were further diminished from the previous session with no European stations reported in North America and WD2XSH/17 receiving reports from three European stations.  Report details can be viewed here.


Doug, K4LY / WH2XZO, took advantage of the return of good band conditions and offered these comments and statistics:

“Transcontinental conditions were quite good with high activity despite elevated K and A indices.  The WH2XZO numbers were 14 and 58 including 2 x WH2XCR and 2 x WG2XSV both indications of good conditions.”

Paul, N1BUG, reported a quiet night in Maine with decodes of thirteen WSPR stations.  Paul indicates no transcontinental or trans-Atlantic reports during this session.

Al, K2BLA / WI2XBV, reported that he had a decent night, providing decodes for twelve WSPR stations and receiving reports from 39 unique stations including two-way reports with WH2XCR.

Ken, K5DNL / WG2XXM, reported that he provided reports for fourteen WSPR stations and he received reports from 67 unique stations.  Ken indicated good domestic propagation and two-way reports with WH2XCR.  Ken also noted reception reports from WH2XCR at 1258z, after local sunrise.

Mike, WA3TTS reported that, “The path was open to KH6 and PNW overnight, but not as good as the previous evening….Best WSPR DB search by distance results below:”

“Either Larry went QRT after 0700 or the propagation path evaporated…..I’m guessing he went QRT as VE7BDQ was captured through most of the overnight session…”

Hideo, JH3XCU, posted links to two tables showing US -> JA DX totals and US -> JA peak S/N for the session.

Roger, VK4YB, reported storms in his area prior to sunset prevented another session of early trans-Pacific reports.  In fact, Roger indicates that the first DX reports came three hours after sunset once storms had moved off to sea.  Openings to North America were quite good, however.  Continuing his 630m / 160m experiment with VE6XH, Roger reports, “160m 7 spots, best -20, 630m 19 spots, best -21.”  On 630-meters, Roger received reports from VE6XH, VE7BDQ, VE7SL, and W7IUV.  He provided reports for WH2XXP and WH2XGP.

Larry, W7IUV / WH2XGP, provided reports for eleven WSPR stations and was reported by 46 unique stations including VK4YB.  As W7IUV, Larry provided reports for eight WSPR stations including VK4YB.

Ward, K7PO / WH2XXP, received reports from 72 unique stations including JA1NQI, JA8SCD5, VK4YB, VK2XGJ and ZL2AFP.

Ron, WA4JNX, reports that the Heathkit HD-1420 that is available on consignment at Ham Radio Outlet can be viewed and purchased here.  There have been a few inquiries so if you want it, don’t wait!  It may already be gone!

I was QRV for a bit during the evening but a storm system moved in after dark so I shut down for the night.  Tonight may be more of the same.

Eden, ZF1EJ, continued in a “receive-only” capacity as his station is operating in the ARRL DX phone contest this weekend.  Eden experienced a significant improvement over the previous session with reports for ten WSPR stations including WH2XCR.

ZF1EJ 24-hour WPR activity


Laurence, KL7L / WE2XPQ, reported high attenuation overnight but managed to sneak a signal out of Alaska.  He also provided reports for VK4YB and shared two-way reports with WH2XCR.  Those report details can be viewed here.

Merv, K9FD/KH6 / WH2XCR, enjoyed a strong night with reports from 7L1RLL4, JA1NQI, JA3TVF, JH3XCU, JR1IZM, VK2XGJ, ZF1EJ and two-way reports with VK4YB.  Merv even received very late reports with JA1NQI near sunrise.  North American coverage was strong including two-way reports in the eastern US shared with WG2XKA, WI2XBV, and WH2XZO.  Eastern reports were quite good which is typical at Merv’s latitude even under active geomagnetic conditions.  Merv’s DX report details can be viewed here.
