Strong geomagnetic storm conditions push trans-Atlantic and trans-Pacific openings toward lower latitudes

– Posted in: 630 Meter Daily Reports, 630 Meters

The details for March 3, 2016 can be viewed here.

Most of the lightning QRN from the previous session was gone from North America during this session although I found that my normal S0 – S1 noise floor during the late afternoon was now S3 across the MF and LF spectrum.  These levels persisted through the evening and I can only imagine that it was related to current geomagnetic conditions.  I’ve observed this noise behavior before when a geomagnetic storm was in progress but it has been some time.  The storms in Mexico and Central America did not seem to cause many problems overnight.

12-hour North American lightning summary

 

Geomagnetic conditions remain at unsettled to storm levels and the Bz is currently pointing to the South with solar wind velocities averaging near 700 km/s.  DST values continue to undulate at negative levels with minima, exceeding lows from the previous session at times.

 

 

 

Trans-Atlantic openings favored lower latitudes during this session as higher latitude absorption was elevated due to geomagnetic storm conditions.  Reports were down for this session but that is not unexpected although as the Northeast experienced a decrease in reports, openings to the South and Southwest were enhanced.  Report details can be viewed here.

WH2XXP -> DJ0ABR

WG2XXM  -> DJ0ABR

EA5DOM -> WI2XBV, WH2XZO, N1BUG, WD2XSH/17

WD2XSH/17 -> DJ0ABR, EA5ZL, EA7HPM, EA8/LA3JJ, EB8ARZ, F1AFJ, F59706, F5WK, F6GEX, G0LUJ, G3XKR, G4KPX, G8HUH, G8LCO, ON5KQ, PA0O, PA0RDT, PA3ABK/2, SV2DCD

Paul, N1BUG, reported that he decoded eleven WSPR stations including EA5DOM.  Paul noted that high latitude propagation was poor overall.

Phil, VE3CIQ, reported that he decoded seven WSPR stations and was decoded by 34 unique stations.  Phil indicates that he must be getting an ERP boost from the cold weather.

Al, K2BLA / WI2XBV, reported good band conditions this morning, marking the second consecutive day of low noise in Florida. Al received reports from 33 unique stations and reported eleven WSPR  stations including WH2XCR.

Doug, K4LY / WH2XZO, reported a strong session in South Carolina with a decrease in QRN.  In spite of high latitude attenuation due to the geomagnetic storm, Doug received reports from 47 unique stations with the most distant station being WG2XSV.  He decoded thirteen WSPR stations with WH2XCR and EA5DOM exceeding 7000 km in distance.

Neil, W0YSE/7 / WG2XSV, reported good transcontinental conditions for a second night and offered these comments and statistics:

Rick, W7RNB / WI2XJQ, indicates that he experienced a moderately successful session, decoding eight WSPR stations and receiving reports from 29 unique stations.  Rick’s unique report details can be viewed here.

Trans-Pacific report details for this session, excluding KL7 and KH6, can be viewed here.

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

Roger, VK4YB, indicates significantly improved openings to Australia from North America.  The path moving North was tougher, however.  He reports, “WG2XXM and WH2XXP decoded 23 minutes before sunset with WH2XGP coming in right on sunset. After that TP died until nearly midnight. VK/ZL propagation was normal throughout.  630m/160m tests with VE6XH continue. 160m 4 spots, best -26, 630m 3 spots, best -23.”  Roger received reports from VE6XH and W7IUV.  He provided reports for WG2XXM, WH2XXP, and WH2XGP.

Ken, K5DNL / WG2XXM, reported that he decoded fifteen WSPR stations and was decoded by 67 unique stations including VK4YB and the previously reported DJ0ABR.

Larry, W7IUV / WH2XGP, provided reports for fifteen WSPR stations, including VK4YB, VK2XGJ, and ZL2AFP.  He received reports from fifty unique stations. As W7IUV, Larry provided reports for nine WSPR stations, including VK4YB.

Ward, K7PO / WH2XXP, received reports from 72 unique stations including VK4YB, 7L1RLL4, JA1NQI, JH3XCU, JR1IZM and the previously reported DJ0ABR.

Joseph, NU6O / WI2XBQ, reported, “A very good night, heard by 31, 12 over 2500km. Including zf1ej and ja1nqi, .5W ERP.”

Here in Texas this session turned out to be pretty good.  I knew that with the low noise and stormy geomagnetic conditions this was going to be a good session to sit back and watch the drama unfold.  My latitude was quite active with very strong domestic openings which resulted in near 1000 reception reports for stations around North America.  East / West paths clearly dominated the session.  While I did not register any trans-Atlantic reports during this session, reports were very strong, including a number of harmonic reports that seem to be most common during these periods of high geomagnetic activity.  It was an exciting night to watch develop.  My transmission report details can be viewed here and my reception report details can be viewed here.

WG2XIQ 24-hour WSPR activity

 

WSPR activity by itself was very high during the evening with 140 MF WSPR stations observed 0215z on the WSPRnet activity page.  Note that this count is notoriously low as stations are left out of the totals so its likely that over 150 stations were active during the same time period.

Eden, ZF1EJ, provided reports for fourteen WSPR stations including WH2XCR.  He was decoded by 38 unique stations.

Laurence, KL7L / WE2XPQ, is QRT but reports that he will probably be QRV again on Sunday.

Merv, K9FD/KH6 / WH2XCR, continues to experience great openings to Japan, with reports from 7L1RLL4, JA1NQI, JH3XCU, and JR1IZM.  The path to Oceania was less spectacular during this session although Merv shared two-way reports with VK4YB and received reports from ZL1BPU.  In North America, the Northeast was generally absent  from reports although the Midwest provided a number of reports and southeastern regions were successful in being reported in Hawaii.  There were no eastern two-way reports during this session, however.  Merv reported yesterday that his noise has been slow to abate after the recent frontal system passed his location on Molokai.  DX report details for this session can be viewed here.
