Last night the band exhibited really strong propagation here in North America.  A forecast geomagnetic storm had not arrived and band conditions were very quiet.  The spotlight was once again dancing around.  John, WA3ETD / WG2XKA, reported that the high latitude transcontinental path to the Pacific Northwest was open in both directions, with reception reports from John, VE7BDQ.  Long haul reports were occurring much earlier than in previous session and John, WA3ETD / WG2XKA, also reported that he had 39 unique reporting stations uploading spots of his signal through the session.  Doug, K4LY / WH2XZO, reported very strong propagation overnight and found that four experimental stations were heard by more than 40 stations through the session:  WG2XIQ – 47, WH2XND – 46, WH2XGP – 41, WH2XZO – 41.  Larry, W7IUV / WH2XGP, reported 11 stations before his system shut down due to antenna icing.

The geomagnetic field was quiet through the session – the calm before the storm.  As I write this, a Sudden Impact Disturbance report was received from the Space Weather Prediction Center indicating that the most recent CME has arrived.  Expect storming conditions through tonight’s session.

The Kyoto DST was stable through the session with a continued progression towards positive values.

G0MRF reports a QRSS3 CW QSO with EA5DOM on 476.16 kHz during the session in the ON4KST chat/logger.  The path was 1432 km and was solid copy in spite of minor QSB.

Paul, W0RW / WA2XRM, operated a CW beacon on 480 kHz but there are no known reports of his signal through the overnight session.  Jim, W5EST, reported no audible CW overnight.  I listened here but there is a very bad broadcast spur on 480 kHz that seems to be the product of a number of stations.

Laurence, KL7L / WE2XPQ, performed ground wave profiles on CW of his station some 35 miles away.  Signals were reported at at that distance at +40db with 350-watts TPO.

At 0143z, Doug, K4LY /  WH2XZO, and I had a CW QSO on 474.5 kHz.  Signals started out strong but QSB took his signal from RST 559  to RST 439 in the span of just a few minutes.  We fought through the variations for a few minutes and signed.  Of course, as we were signing, signals began to peak once again.  This fast QSB has been a characteristic of this season.

Joe, NU6O / WI2XBQ, called CQ on JT9 at 0411z at 474.2 kHz + 1000 Hz.  He was not heard at my station at that time but it was early.  Joe is working on a 500-watt amp and it should be QRV any time now.

Band activity was very high and dominated by WSPR through the session.  At 0200z, 78 MF WSPR stations were reported on the WSPRnet activity page.  The daytime session was almost completely unremarkable and there were no reports through the session.

In Alaska, Laurence, KL7L / WE2XPQ, had a strong session with reports from JA1NQI-2.  Reports from North America are curiously low, however.

In the Pacific, Merv, K9FD/KH6 / WH2XCR, had perhaps the strongest night in a very long time with reports all across North America, with several along the east coast in addition to reports from JA1NQI-2 and a report by John, VK2XGJ, who included a screen shot where a faint wisp of signal can be detected in the waterfall.

Other anecdotes, statistics and comments from the session:

Ron, NI7J / WH2XND, returned to 630-meters from 2200-meters mid-session.  Doug. K4LY / WH2XZO, noted at 0345z that Ron registered a +1 db S/N, which is the strongest signal / furthest away station received at Doug’s station.

Bruce, W1BW, the WSPRnet admin reports that he is now working on WSPRnet server issues.  The system has already been better this morning.  Thanks Bruce!
