Geomagnetic storm conditions return but great trans-Atlantic openings ahead of storm; Good domestic propagation including transcontinental opening; Trans-Pacific openings were good but less robust than previous session

The details from February 24, 2016 can be viewed here.

In spite of Midwestern storms during the evening and overnight, propagation was very good on domestic and trans-Atlantic paths and pretty good on trans-Pacific paths on the lead up to geomagnetic storm conditions.  Reports were lopsided once again, with the bulk of trans-Atlantic decodes coming from European stations for stations in North America.  I expect that this observation is the result of elevated noise levels from storms in the US.

Geomagnetic conditions deteriorated during the evening, with a K-index spiking to 5 followed by a reporting period of unsettled conditions.  Solar wind velocities are high, averaging 615 km/s and DST values decreased in-step with the reported storm conditions.  These elevated geomagnetic conditions are the result of a geoeffective coronal hole which will likely continue to have some impact through the weekend.

 

 

 

Trans-Atlantic openings were very good during the early evening in North America.  A number of reports were registered early in the session on the East coast  and curiously the data shows a number of single, possibly even first time trans-Atlantic reports, during the late 0200z hour, which seems to have been a focal point of openings.  Other “regulars” registered reports through the evening and overnight.  The 0254z openings seems to correspond somewhat with the observed K-index spike.  Report details can be viewed here.

Ken, K5DNL / WG2XXM, reported that he decoded nine WSPR stations and was decoded by 72 unique stations including EA8/LA3JJ and WE2XPQ.

Paul, N1BUG, reported a quiet night in Maine early in the evening followed by noise from the Midwest storms.  QRN wasn’t so bad that it prevented decodes.  In fact, he had early reports of G8HUH at 2238z in addition to F1AFJ and F5WK during the evening.  Paul decoded fifteen stations including WH2XGP in Washington state.

Rick, W7RNB / WI2XJQ,  reports that he did not upload decodes due to a technical issue during the evening but he received reports from 35 unique stations and indicates that it was another good session for this stations and very similar to the previous session.  His unique transmission report details can be viewed here.

Ron, NI7J / WH2XND, reported that he decoded nine WSPR stations using his K9AY loop.

Mike, WA3TTS, was a victim of the Midwestern QRN but managed some transcontinental reports:

Roger, VK4YB, reported that there is a “Large area of active storms throughout Northern VK, PNG and Indonesia making rxing difficult. WH2XXP was decoded once only. 19 stations heard ‘4YB at last count before WSPR lockout”  Roger received reports from W7IUV, CF7MM, VE6XH and VE7BDQ.

Phil, VK3ELV, received reports from JH3XCU late in the previous session.

Ward, K7PO / WH2XXP, received reports from 74 unique stations including JA3TVF, JR1IZM, VK4YB, and ZL2AFP.

Larry, W7IUV / WH2XGP, provided reports for fifteen WSPR stations and was decoded by 57 unique stations including ZL2AFP.  As W7IUV, Larry provided reports for ten WSPR station including VK4YB.

Early evening domestic conditions seemed to be very good and noise from storms in the Midwest  was non-existent here in Texas.  I did not operate CW at 0200z, however, due to a massive sinus headache.  The path to KL7 was open to a degree and I was fortunate to decode WE2XPQ but the path does not appear to have been reciprocal.  My WSPR reception reports were down slightly from the previous session but still quite good.  Those report details can be viewed here.   Transmission reports were typical and quite good and those report details can be viewed here.

Eden, ZF1EJ, provided reports for twelve WSPR stations and was decoded by 27 unique stations including two-way reports with WH2XCR.

Laurence, KL7L / WE2XPQ, was heard by ZL1AFP and provided reports for VK4YB.  The path to VK was likely open but high noise level from local storms made the reciprocity challenging.  Laurence shared two-way reports with WH2XCR including very late, sunrise reports from Merv and was heard at my station in Texas but there was no reciprocal path.  Similarly, WG2XXM located in Oklahoma just 200 miles away was reported by Laurence but he had no reciprocal path.  Laurence’s KH6, VK and ZL report details can be viewed here.

Merv, K9FD/KH6 / WH2XCR, experienced an even better session than the previous with reports from 7L1RLL4, JA3TVF, JH3XCU, and JR1IZM in Asia.  In Oceania, Merv had reports from two ZL stations,  ZL1BPU and ZL2AFP, and VK2XGJ in Australia.  Merv shared two-way reports with VK4YB and provided reports for VK3ELV and VK3HP.  Merv also shared two-way reports with WE2XPQ and ZF1EJ.  Merv provided very late reports for Laurence on what looks like an almost sunlight path from Alaska.  Coverage of North America was very good but was comprised mostly of reception reports for eastern stations due to high noise in the Midwest.  Merv’s JA, VK, ZL and ZF1 report details can be viewed here.
