OFF AIR but hope to be back by 1115z Saturday morning if I don't oversleep

Are this session’s great trans-Atlantic openings due to coronal hole enhancements?; ZF1EJ expands his repertoire with additional DX station reporting overnight; G3KEV -> FR5ZX; WE2XPQ -> JA1NQI

– Posted in: 630 Meter Daily Reports, 630 Meters

This was a session in which I regret not being able to participate.  An evolving weather forecast resulted in a return of afternoon and evening storms.  While it was generally dry overnight I am sure that band noise would have been elevated.  This system was anticipated to move out of the region by noon today but now it seems to have been extended to an all-day event that will likely have an impact overnight.  If there is no possibility for lightning I will be QRV tonight.  There was another noisy storm system off of the Atlantic coast and its remarkable that reception reports from Europe were not impacted more.  Noise in Ocean was reported at moderate to high levels but signals manged to find their way through.

Openings looked strong and the trans-Atlantic path from North America was on fire, particularly for a couple of stations.  The trans-Pacific path showed some life as WH2XXP returned to air after a week in the Caribbean which included a stop at ZF1EJ to complete Eden’s transmit antenna and get him on the air.  The trans-African path was open again as well.

A coronal hole is now geoeffective and geomagnetic conditions have responded accordingly, with elevated Kp-indices for multiple reporting periods  and a variable Bz that is currently pointing to the North.  Solar wind velocities peaked above 600 km/s and DST values showed textbook behavior, peaking before decreasing significantly.  Storm levels have yet to be achieved as DST values rebound rather than free falling and its possible that this “shot across the bow” may have provided enough energy to enhance propagation in mid and lower latitudes in the short term.  I’m not sure yet if I would call this an onset enhancement and perhaps that is coming ahead of a major spike in Kp.  The fact that the DST has rebound so well suggests to me that many of us might be in for a few good session if storm conditions don’t get out of control.

 

 

 

G3KEV was reported on the trans-African path from Europe at FR5ZX.  Report details can be viewed here.  I’m a bit surprised that there were no additional European stations reported on Reunion Island compared to last season when almost ten stations had been reported by this point.  This season is clearly very different.

G3KEV, as reported by FR5ZX

 

Trans-Atlantic openings were probably as robust as have been observed this season and stations on both sides of the Atlantic were able to reap the benefits.  F5WK was a big winner in Europe, receiving reports from VE2PEP, VE3CIQ, WA3TTS, K4RCG, K3RWR, KU4XR, VE1HF, WD2XSH/17, WH2XZO and WG2XPJ.  G8HUH  received reports from K3RWR, WD2XSH/17, and VE1HF.  ZF1EJ received reports from G8HUH and LA2XPA.  Who will be next to report Eden?  VE1HF provided additional reports for F4DTL and G3KEV.  The big winner in North America for this session was WG2XPJ, who received reports from an astonishing number of stations overnight, including EI0CF, F1AFJ, G0LUJ, G0MJI, G3XKR, G8HUH, LA2XPA, PA0RDT, PA3ANG, PA7EY, and PE1RKT.  That’s quite a turn out from the Netherlands!  Report details for these stations can be viewed here.

Doug K4LY / WH2XZO, mixed operating on 630-meters and NDB listening during this session, finding success with decodes of F5WK.  Doug provided the following analysis of his reports compared to others in his region:

“Conditions were fairly noisy again with only 7 decodes and 35 decoded.   Around 9 PM and again at 10 PM I checked the long wave European broadcasters, and several were poor to fair, about Q3 at best- not very good reception. I was surprised when I looked this morning to see F5WK was heard widely on the east coast.  When I looked at the two receiving stations closest to me who decoded F5WK, it was odd that my 3 receptions to not coincide with theirs. I was transmitting 30% of the time, but that’s an explanation for only one K4RCG decode not recorded here.

Unfortunately, I was NDB DXing and not monitoring 630M for 8 of their KU4UR and K4RCG decodes below, right up until 0316, so missed almost half the opening.  I was not monitoring when KU4XR had his two decodes, but KU4XR was monitoring when I decoded F5WK 3 times, and he did not decode. However, KU4XR two decodes did occur when K4RCG, to the northeast, was also decoding F5WK.
Of the 11 time periods when all three nearby stations were monitoring, on only one time period, 0346, was there decoding by more than one station.
WH2XZO and KU4XR separated by only 189 km, and also WH2XZO and K4RCG separated by less than 500 km were receiving F5WK and different times. One interpretation is that he F5WK footprint was small and changing, not covering a large area.  Interesting!”

 

Rick, W7RNB / WI2XJQ, reported that his spotlight continues to shine on the Southeast with reports from KU4XR and ZF1EJ.  Rick was cut short in the West as WH2XCR was not QRV during this session and notes that activity seemed down overall.  He adds that heavy rain and some flooding are impacting his area and I can vouch for many of us being off air due to bad weather conditions.  Rick  received reports from 25 unique stations and provided reports for four WSPR stations.  Rick’s unique report details can be viewed here.

 

Mike, WA3TTS, reported “…Strange conditions overnight with the geomag event. I had three F5WK captures during the event, then the band conditions seemed to dry up with no NW transcon or XCR decodes overnight.”

Trans-Pacific report details, excluding KL7 and KH6,  are aggregated here.

Roger, VK4YB, reported “High absorption on VK and DX signals tonight. VK stations were 8 to 10 dB below par. Static was moderate to high. Ward reached -20 but no other dx signals were visible.”

Ward, K7PO / WH2XXP, received reports from 59 unique stations including VK4YB and VK2XGJ.

Regional and continental WSPR breakdowns follow:

North American 24-hour WSPR activity

 

European 24-hour WSPR activity

 

African 24-hour WSPR activity

 

Central / Asiatic Russian 24-hour WSPR activity

 

Japanese 24-hour WSPR activity

 

Australian 24-hour WSPR activity

 

Eden, ZF1EJ, was reported by G8HUH for the first time and LA2XPA for the fourth consecutive session (included in trans-Atlantic report details above).   It seems that the common denominator with these stations is their proximity to salt water so perhaps this bodes well for stations further south once geomagnetic conditions relax.  Eden continues to hear well.

Laurence, KL7L / WE2XPQ, transitioned to synchronized WSPR transmissions on 472 and 137 at 0742z and managed to find an opening to JA1NQI.  His North American reports were limited to the western US and Laurence’s listening appears to have been  degraded by either precipitation static and the elevated geomagnetic conditions.  he indicated this morning that the K-index was at 5.   Laurence’s JA report detail can be viewed here.

Merv, K9FD/KH6 / WH2XCR, was QRT during this session.
