Weekly Propagation Summary – 2018 Feb 19 16:10 UTC

Weekly Propagation Summary (2018 Feb 19 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2018 Feb 19 0416 UTC.

Highlights of Solar and Geomagnetic Activity 12 – 18 February 2018

Solar activity was at very low levels on 13-18 Feb and low levels on 12 Feb. The strongest flare of the period was a C1 from Region 2699 (S07, L=165, class/area Dai/240 on 10 Feb) at 12/0135 UTC. The event produced an associated asymmetric halo signature first observed in SOHO/LASCO C2 imagery at 12/0125 UTC. Analysis and modeling of the event suggested arrival of the CME at Earth on 15 Feb.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at background levels 12-16 Feb. An increase to moderate levels on 17 Feb and to high levels on 18 Feb was observed in response influence from a negative polarity CH HSS.

Geomagnetic field activity ranged from quiet to active levels. Quiet conditions were observed on 12-14 Feb. On 15 Feb, arrival of the 12 Feb CME produced only one isolated period of active during the day. Total magnetic field strength increased to a peak of 15 nT around 16/0530 UTC while Bz remained mostly positive. Solar wind speeds were relatively slow, between 300-400 km/s through the event. Active levels were reached again on 17 and 18 Feb in response to influence from a negative polarity CH HSS. Solar wind speeds continued to increase over the two days to a peak of about 600 km/s late on 18 Feb.

Forecast of Solar and Geomagnetic Activity 19 February – 17 March 2018

Solar activity is expected to be very low through 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 from CH HSS influence are expected from 19-25 Feb. A transition back to normal levels is expected from 26 Feb to 17 Mar.

Geomagnetic field activity is expected to range quiet to G1 (Minor) geomagnetic storm conditions. Influence from a negative polarity CH HSS is expected to produce isolated periods of G1 (Minor) storming on 19 Feb. A decrease to quiet to active levels by 20 Feb and quiet to unsettled levels over 21-23 Feb is expected as influence from the CH HSS slowly wanes. Quiet to unsettled levels are again expected on 04 Mar and 15 March, with quiet to active levels expected on 14 Mar and 16-17 Mar, as multiple, recurrent CH HSSs are anticipated to become geoeffective. The remainder of the outlook period is expected to observe quiet conditions.

Let’s Call CQ – QSO Today Episode 184 with NW7US

I got a Skype call a few weeks ago from Eric, 4Z1UG–the creator and host of the QSO Today Podcast–during which he asked me about how and why I got into amateur radio.  Here’s the result.

Eric writes,

We talk a lot about the band conditions due to the Sunspot cycle. Most of it on Facebook and other places is about how “dead” the bands are at this point. We all can’t wait until the cycle starts to rise and we will be making contacts with little effort. I remember in my conversation with Chuck Adams, K7QO in Episode 58, that he really enjoys operating is “Pigrig”, one watt, CW transceiver on 20 meters. When I asked him, (I liberally paraphrase) “but Chuck, the bands are dead. How does that work for you?”. His reply was that while most hams are listening to the bands, he calls CQ until he gets a reply. Works every time.

My QSO this week is with Tomas Hood, NW7US, who has years of expertise in propagation and Solar activity. He is the propagation editor of more than a few radio magazines and websites. In our post-recording conversation we discussed this phenomenon of listening and not calling CQ. I even had this idea that maybe one of the reasons that the digital modes are so successful is because they “beacon”, as part of the whole digital experience, the same as calling CQ. This is why they make contacts. From what I see, looking at PSK Reporter, hams are making lots of contacts worldwide using the digital modes. While SSB may not be working so well, CW and the digital modes seem to work fine.

I like to work on my bench or make the podcast while listening to the bands. Jeff Damm, WA7MLH, in Episode 177, says that he will put his keyer in CQ mode while he is working on a new radio. Invariably, sometimes after many minutes, he gets a reply. Great idea Jeff!

73,

Eric, 4Z1UG

Highlights of Episode 184:

Tomas Hood, NW7US is the propagation editor of a number of shortwave and amateur radio magazines, and has a wide variety of websites, that grew out of his love for all things radio, and for listening on the bands to far off DX and commercial broadcast stations. Tomas shares his understanding of propagation and the lessons we can learn from listening, really listening to the QSOs and exchanges during contest operation.

All of the QSO Today episodes are great.  I enjoy hearing about many different hams.  Do check out all of the episodes that Eric has published.

Weekly Propagation Summary (2018 Feb 12 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2018 Feb 12 0146 UTC.

Highlights of Solar and Geomagnetic Activity 05 – 11 February 2018

Solar activity was at very low levels on 05, 08-09 and 11 Feb while low levels were observed on 06-07 and 10 Feb. All of the period's activity originated from Region 2699 (S07, L=165, class/area Dai/240 on 10 Feb). The largest observed event was a C8 flare observed at 07/1347 UTC. No Earth-directed CME activity was detected during the period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels the entire period.

Geomagnetic field activity was at predominately quiet levels under a nominal solar wind regime. Isolated unsettled intervals were observed on 05, 09 and 10 Feb.

Forecast of Solar and Geomagnetic Activity 12 February – 10 March 2018

Solar activity is expected to be at very low to low levels, with a chance for M-class activity, through 16 Feb due to the flare potential of Region 2699. Very low levels are expected from 17-28 Feb. A return to very low to low levels, with a chance for M-class activity, is possible from 01-10 Mar after the return of old Region 2699.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal to moderate levels on 12-25 Feb, with a chance for high levels on 19 Feb, due to influence from recurrent CH HSSs. Mostly normal levels are anticipated on 26 Feb – 10 Mar.

Geomagnetic field activity is expected to be at quiet to unsettled levels on 15-18 Feb, 20-22 Feb and 04 Mar, with isolated active periods likely on 16 Feb. This activity is due to influence from recurrent CH HSSs. Mostly quiet conditions are expected for the remainder of the outlook period.

Weekly Propagation Summary (2018 Feb 05 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2018 Feb 05 0144 UTC.

Highlights of Solar and Geomagnetic Activity 29 January – 04 February 2018

Solar activity was at very low levels from 29 Jan – 03 Feb. Low levels were observed on 04 Feb as new Region 2699 (S04, L=171, class/area Hsx/080 on 04 Feb) produced a C1 flare at 04/2024 UTC. The region also produced numerous B-class flares after rotating onto the disk. No Earth-directed CME activity was observed during the period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at moderate levels on 29 Jan with a peak flux of 130 pfu observed at 29/0005 UTC. Normal levels were observed from 30 Jan – 04 Feb.

Geomagnetic field activity was at mostly quiet levels with isolated unsettled intervals observed early on 30 Jan and again late on 31 Jan.

Forecast of Solar and Geomagnetic Activity 05 February – 03 March 2018

Solar activity is expected to be to be at mostly very low levels with a slight chance for low activity through 16 Feb due to the emergence of Region 2699. Very low levels are anticipated from 17-28 Feb after the departure of Region 2699. A slight chance for low levels is possible from 01-03 Mar due to the return of old Region 2699.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal levels from 05-14 Feb and again from 26 Feb-03 Mar. Moderate levels are likely from 15-25 Feb due to influence from recurrent CH HSSs.

Geomagnetic field activity is expected to be at quiet to unsettled levels on 05 Feb, 15-17 Feb and 20-22 Feb, with isolated active periods likley on 16 Feb. This activity is due to influence from recurrent CH HSSs. Mostly quiet conditions are expected for the remainder of the outlook period.

What Got You Interested in Radio? What Hooked You? (Story Time, with Video)

What got you interested in radio? What hooked you?

I’ve been asked, “What got you interested in radio, space weather, and the science of radio-wave propagation?”

Here’s a short answer as to why (and when) I became a radio enthusiast. It all started…

[embedyt] https://www.youtube.com/watch?v=0XBth62JgwA[/embedyt]

https://www.youtube.com/watch?v=0XBth62JgwA

The following picture is of my first shortwave radio, discovered in my home sometime between 1971 and 1973: a Sony portable transistorized four-band radio receiver. This was my very first shortwave radio (well, truthfully, it was my dad’s). This radio is responsible for my love of radio, electronics, and communications.

Sony Portable 4-Band Radio - the model 7F-74DL (my First Radio)

Sony Portable 4-Band Radio – the model 7F-74DL (my First Radio)

I still use this, sometimes, when listening to late-night AM-broadcast-band-radio DX. It is horrible for shortwave radio listening, as it has no noise blanker. For MW (Medium-wave) AM Broadcast DXing at night, it is excellent. The internal bar antenna is very directional so I can rotate the radio around until I get the best reception of some station. Back when I was a child, that made the radio very fun to use.

This next radio is a really capable military surplus radio circa WWII or shortly after (the late 1940s, early 1950s). This radio was my world starting around 1975. From Medium-wave to Shortwave, this radio could hear a pin drop around the world! Many late nights when I was supposed to be sleeping, I was up with the light dimmed and the tubes singing signals from exotic places.

LETTER TO ARRL REGARDING CURRENT BOARD OF DIRECTOR ACTIVITIES

The following open letter to the ARRL Board of Directors and Leadership is in concert with many others coming from current members in response to the activities occurring at the ARRL Leadership level.

To join in and voice your thoughts, please visit:

We strive to make the activities of ARRL leadership more transparent by insisting on the creation and dissemination of records of the deliberations and actions of all ARRL Boards, Committees, and the operational Executive Team.
(More information is found after the following open letter)

 


To: All ARRL Directors and Officers

From: NW7US

Many actions–policy and governance–taken by the League’s leadership over the past two years trouble me. Formalization of specific actions planned for the Board meeting on January 19, 2018, specifically worries me.

At this time, any action taken by the ARRL Board of Directors cause me concern. As a result of this, I add my name to those seeking that the Board delay consideration of any ByLaw changes at the January 19 Board meeting.

In particular, I strongly urge you to:

1. Reject any proposal to allow the President and individual Vice-Presidents to vote as Directors.

2. Reject any provision that allows expulsion of an ARRL member “for cause” without delineated criteria.

3. Reject any provision that allows expulsion of any Director, Vice-Director of Officer for bringing ARRL into “disrepute” without specific criteria.

4. Reject any provision that reduces Members’ ability to recall a sitting Director.

5. Reject any current or proposed provision that allows the Board to disqualify candidates for elected office without full disclosure of the reasons for such disqualification.

6. Reject any proposal that would allow the Board to designate replacements for Directors instead of appointing an elected Vice Director or other elective processes.

7. Reject any current or proposed provision that allows censure, removal or other disciplines of a Director for revealing or openly discussing any view expressed at a Board meeting that is not consistent with the Board’s action.

8. Adopt a policy that elected Directors, and Vice Directors are not “personnel” for the purposes of declaring that any information about removal or disqualification is confidential and may not be released.

It is crucial that ARRL remain a solidly democratic, membership-based organization with principles of openness and accessibility through our elected Directors. I urge you to vote per my wishes at the January 19 meeting.

Beyond these issues of governance, I am concerned about the policy-making process of the ARRL leadership–leadership that I feel has become much less Member-driven, and that no longer reflects the needs of the Membership.

Ham radio is in a time of transition. The ARRL must focus on the issues that make a difference for the future success of the hobby.

73, Tomas Hood / NW7US
