Weekly Propagation Summary – 2019 Apr 29 16:10 UTC

Weekly Propagation Summary (2019 Apr 29 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2019 Apr 29 0213 UTC.

Highlights of Solar and Geomagnetic Activity 22 – 28 April 2019

Solar activity was very low throughout the reporting period. No spotted regions were observed on the solar disk. No Earth-directed CMEs were observed in available coronagraph imagery.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at moderate levels on 22-23 Apr and decreased to normal levels for the remainder of the reporting period.

Geomagnetic field activity ranged from quiet to unsettled. A solar sector boundary crossing was observed late on 23 Apr which caused several periods of unsettled early into 24 Apr. No other significant signatures were observed in the solar wind data. Quiet conditions were observed for the remainder of the reporting period.

Forecast of Solar and Geomagnetic Activity 29 April – 25 May 2019

Solar activity is expected to be at very low levels over the outlook period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to range from normal to high levels. High levels are expected on 02-12 May; moderate levels are expected on 29 Apr-01 Mar and 13-23 May. The remainder of the outlook period is expected to be at normal levels.

Geomagnetic field activity is expected to range from quiet to active levels. Active levels are expected on 01-02 May and 07 May; unsettled levels are expected on 30 Apr, 03 May, 05-06 May, 08-10 May and 19 May. The remainder of the outlook period is expected to be at quiet levels. All enhancements in geomagnetic activity are due to the anticipation of multiple, recurrent CH HSSs.

Put That ARRL CEO to Work, Would Ya?

In a recent episode of the ICQ Podcast, I had Howard Michel WB2ITX as my interview guest. He’s the CEO of the American Radio Relay League as of late last year. It was important that Howard get interviewed about League matters as he was hired after a brief misfire to replace the legendary CEO David Sumner K1ZZ. As I told ARRL President Rick Roderick in the Q&A session with him a year or so ago at the Mississippi Section Convention in Jackson, MS, “You guys made a mistake in hiring someone from Wall Street to be CEO of a membership non-profit organization. Don’t make one again.” My Division Director, David Norris K5UZ, was seated in the row in front of me, nodded his head and turned to give me a knowing look. From my interview with Howard Michel, and from what else I’ve seen coming from him, they did not make a mistake.

One of the strategic matters that this new CEO faces is the common perception that Chief Executives are walled-off from the organization’s customers or just come out of their catacombs to glad-hand, smile, and ask for something.

Indeed, if you listen to my interview with him here, I think you’ll find that he has a clear but not tight-fisted vision for making the Headquarters more customer service oriented, inclusive, and modern in it’s business operations. This should yield better service experiences for members. Perhaps equally important, it may attract new members to the League as the 150,000 or so current members pale by comparison to the 750,000 licensed hams in the U.S.

One of the strategic matters that this new CEO faces is the common perception that Chief Executives are walled-off from the organization’s customers or just come out of their catacombs to glad-hand, smile, and ask for something. As error prone as this perception is, there is enough of an everyday reality that validates it to the rank-and-file customer base to make it the default mental setting, so to speak. In addition, there’s the “We’re the ARRL. And You’re Not!” barrier (apologies to the comedian Chevy Chase of Saturday Night Live fame).

As I was listening to Howard respond to my questions, I was pondering these matters. It hit me that it might be informative for all involved if there were opportunities to interact with Howard as just another ham operator so as to “see” him that way as opposed to a mostly a face with a monthly column in QST or on the pages of the ARRL’s website. An idea was formulated on the spot: get him on the air in a mini-event so as to work Howard on the air at W1AW!

So I sprang this on him without any real sense of how he would respond by asking a one of my final questions: How’d you like to make some news? I proposed that we set up a date and time to appear on W1AW’s station on 20 meters and let the ICQ Podcast team promote it as a joint mini-event where hams could “put the CEO to work” by working WB2ITX on the air. He immediately caught the humorous pun in this and agreed enthusiastically.

Please put May 13, 2019 at 2:00pm Eastern Time on your calendars. Tune your antennas, rigs, and amplifiers (if you have them) to 14.254+/- and put that CEO to work! Howard promises a special QSL card from the League HQ for worked contacts.

Hunting For NDBs In CLE243

YPM - 274 courtesy: VE3GOP



This coming weekend will see another monthly CLE challenge. This time the hunting grounds will be 270.0 - 319.9 kHz.

 





For those unfamiliar with this monthly activity, a 'CLE' is a 'Co-ordinated Listening Event', as NDB DXers around the world focus their listening time on one small slice of the NDB spectrum.

If you've been meaning to participate in  CLE, then maybe this weekend is a fine time to try!

A nice challenge in this one is to hear YPM - 274, located in northwest Ontario near Pikangikum.

'YPM' runs just 25W into a 100' vertical but is well-heard throughout North America. Listen for its upper-sideband CW identifier (with your receiver in the CW mode) on 274.368 kHz.

Summer lightning storms may provide additional listening challenges but maybe we will get lucky.

When tuning for NDBs, put your receiver in the CW mode and listen for the NDB's CW identifier, repeated every few seconds. Listen for U.S. NDB identifiers approximately 1 kHz higher or lower than the published transmitted frequency since these beacons are modulated with a 1020 Hz tone approximately.

For example, 'AA' near Fargo, ND, transmits on 365 kHz and its upper sideband CW identifier is tuned at 366.025 kHz while its lower sideband CW ident can be tuned at 363.946 kHz. Its USB tone is actually 1025 Hz while its LSB tone is 1054 Hz.

Often, one sideband will be much stronger than the other so if you don't hear the first one, try listening on the other sideband.

Canadian NDBs normally have an USB tone only, usually very close to 400 Hz. They also have a long dash (keydown) following the CW identifier.

All NDBs heard in North America will be listed in the RNA database (updated daily) while those heard in Europe may be found in the REU database. Beacons heard outside of these regions will be found in the RWW database.

From CLE organizer Brian Keyte, G3SIA, comes the details:

 Hello all

Our 243rd co-ordinated listening event is this weekend, covering a 50 kHz
frequency range - about three times wider than usual. 

    Days:     Friday 26 April - Monday 29 April
    Times:   Start and end at midday, your LOCAL time
    Range:   270.0 - 319.9 kHz  (NDB signals only)

In part of the frequency range it might be quite a challenge to tease out
the NDB signals from among the DGPS ones.
Any first-time CLE logs will be very welcome, as always.

Please log the normal NDBs you can identify that are listed in the range
(it includes 270 kHz but not 320 kHz).

Please send your CLE log to NDB List, if possible as a plain text email
and not in an attachment, with 'CLE243 FINAL' at the start of its title.

Show on EVERY line of your log:
  #   The Date  e.g. '2019-04-26', etc.  (or just '26')
  #   UTC  (the day changes at 00:00 UTC).
  #   kHz  - the beacon's nominal published frequency if you know it.
  #   The Call Ident.

Those main items can be in any order within themselves, but BEFORE any
other optional details (Location, Distance, etc.) later in the same line.

As always, give details in your log of your own location and the receiver,
aerial(s), etc. that you were using.
If you send any interim logs, be sure to send a FINAL (complete) one.

You can find anything else to help you, including CLE seeklists for your
part of the World, from the CLE page, http://www.ndblist.info/cle.htm

Please look out for our 'Any More Logs?' email at about 17:00 UTC on
Tuesday so that you can check that your CLE log has been found OK.

Do make sure that your log has arrived at the very latest by 08:00 UTC
next Wednesday, 1st May.
We are hoping to make all the combined results within a day or two.

Enjoy your listening
Brian and Joachim

(Reminder:  You could use any one remote receiver for your loggings,
stating its location and owner - with their permission if required.
A remote listener may NOT also use another receiver, whether local
or remote, to obtain further loggings for the same CLE).

These listening events serve several purposes. They:
  • determine, worldwide, which beacons are actually in service and on-the-air so the online database can be kept up-to-date
  • determine, worldwide, which beacons are out-of-service or have gone silent since the last CLE covering this range
  • will indicate the state of propagation conditions at the various participant locations
  • will give you an indication of how well your LF/MF receiving system is working
  • give participants a fun yet challenging activity to keep their listening skills honed

The NDB List Group is a great place to learn more about the 'Art of NDB DXing' or to meet other listeners in your region. There is a lot of good information available there and new members are always very welcome. As well, you can follow the results of other CLE participants from night to night as propagation is always an active topic of discussion.

You need not be an NDB List member to participate in the CLEs and all reports, no matter how small, are of much value to the organizers. 

Remember - 'First-time' logs are always VERY welcome!

Reports may be sent to the NDB List Group or e-mailed to CLE co-ordinator, Brian Keyte (G3SIA), whose address appears above. If you are a member of the group, all final results will also be e-mailed and posted there.

Please ... give the CLE a try ... then let us know what NDB's can be heard from your location! Your report can then be added to the worldwide database to help keep it up-to-date.

Have fun and good hunting!

Weekly Propagation Summary (2019 Apr 22 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2019 Apr 22 0049 UTC.

Highlights of Solar and Geomagnetic Activity 15 – 21 April 2019

Solar activity was very low throughout the period. Region 2738 (N06, L=301, class/area-Hhx/400 on 17 Apr) produced several B-class events including a B8 flare at 20/0050 UTC. Region 2739 (N05, L=258, class/area-Cro/20 on 18 Apr) was inactive and stable during its migration across the solar disk. No Earth-directed coronal mass ejections (CMEs) were observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 15 April with moderate levels observed throughout the remainder of the reporting period.

Geomagnetic field activity reached unsettled levels on 15-16 April due to coronal hole high-speed stream (CH HSS) influence. Quiet conditions were observed throughout the remainder of the reporting period.

Forecast of Solar and Geomagnetic Activity 22 April – 18 May 2019

Solar activity is expected to be very low throughout the outlook period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 02-12 May with normal to moderate levels expected throughout the remainder of the outlook period.

Geomagnetic field activity is expected to reach active levels on 27 April and 01-02, 07 May in response to several recurrent, negative-polarity CH HSSs. Quiet to unsettled levels are expected throughout the remainder of the outlook period.
