Weekly Propagation Summary – 2020 Jul 06 16:10 UTC
Here is this week’s space weather and geophysical report, issued 2020 Jul 06 0150 UTC.
Highlights of Solar and Geomagnetic Activity 29 June – 05 July 2020
Solar activity was very low. Region 2766 (N06 L=117, class/area Bxo/beta on 04 Jul) was the only active region on the visible disk. The region was in decay at the end of the reporting period.
Other activity included a DFS, approximately 18 degrees in length, which erupted in the SE quadrant beginning around 05/0630 UTC. Subsequent SOHO/LASCO C2 imagery showed the related CME signature after 05/1412 UTC. Analysis for an Earth-directed component is ongoing.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal background to moderate levels.
Geomagnetic field activity ranged from quiet to unsettled. Unsettled levels were observed on 01 Jul due to sustained southward Bz and on 04-05 Jul in response to a positive polarity CH HSS. The remainder of the summary period was at quiet levels under nominal solar wind conditions.
Forecast of Solar and Geomagnetic Activity 06 July – 01 August 2020
Solar activity is expected to be at very low levels 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 be normal background to moderate levels throughout the outlook period.
Geomagnetic field activity is expected to be at quiet to unsettled levels. A recurrent positive polarity CH HSS is expected to cause isolated unsettled levels on 06 Jul and again on 31 Jul – 01 Aug. The remainder of the outlook period is expected to be at quiet levels. Analysis and modeling of the 5 Jul CME is not complete and the presence of an Earth-directed component is possible.

Weekly Propagation Summary – 2020 Jun 08 16:10 UTC
Here is this week’s space weather and geophysical report, issued 2020 Jun 08 0136 UTC.
Highlights of Solar and Geomagnetic Activity 01 – 07 June 2020
Solar activity was at very low levels with numerous B-class flares observed from new Region 2765 (S24, L=116, class/area Cao/130 on 05 Jun). This reverse polarity region was mostly stable since it rotated onto the disk on 03 Jun. No Earth-directed CMEs were observed during the period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels through the period.
Geomagnetic field activity was at mostly quiet levels, with some isolated unsettled periods late on 01 Jun through early 02 Jun. A nominal solar wind environment was prevalent with wind speeds ranging from 300-400 km/s, total field (Bt) 5 nT or less and the Bz component mostly neutral.
Solar wind parameters became enhanced after midday on 07 Jun. Wind speeds increased to near 475 km/s, Bt reached a maximum of 13 nT and Bz reached a maximum southward extent of -8 nT. A suspected weak, positive polarity CH HSS resulted in this enhanced wind environment. The geomagnetic field reacted with unsettled to active conditions the last half of 07 Jun.
Forecast of Solar and Geomagnetic Activity 08 June – 04 July 2020
Solar activity is expected to be at mostly very low levels. A slight chance of low level activity exists through 15 Jun while Region 2765 remains on the visible disk. Very low levels will then persist through 28 Jun. Old Region 2765 (S24, L=116) is expected to return after 28 Jun with a possible increase in low level flare activity to a slight chance.
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 through the outlook period.
Geomagnetic field activity is expected to be at unsettled to isolated active levels on 08 Jun due to influence from a weak, positive polarity CH HSS. From 09 Jun to 04 Jul, mostly quiet levels are anticipated.

Weekly Propagation Summary – 2020 Jun 01 16:10 UTC
Here is this week’s space weather and geophysical report, issued 2020 Jun 01 0138 UTC.
Highlights of Solar and Geomagnetic Activity 25 – 31 May 2020
Solar activity reached moderate levels on 29 May due to an M1.1 flare at 0724 UTC from an unnumbered region beyond the northeast limb. This region also produced a C9.3 flare at 29/1046 UTC. Both flares were believed to cause CMEs off the eastern limb. However, no Earth-directed CMEs were observed in LASCO coronagraph imagery. Very low activity was observed for the remainder of the summary period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal background levels.
Geomagnetic field activity was quiet to unsettled for the period. There was possible CME influence on 30 May. The IMF was enhanced to a peak of 14 nT near 30/0500 UTC, while the Bz component reached a maximum southward deflection of -13 nT at 30/0520 UTC. However, the geomagnetic field only managed unsettled levels.
Forecast of Solar and Geomagnetic Activity 01 June – 27 June 2020
Solar activity is expected to be very low for the period.
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 for the forecast period.
Geomagnetic field activity is expected to be at mostly quiet levels for the period.

One Aspect of Amateur Radio: Good Will Ambassadors to the World
This article is part two of the series taking a look at band plans and gentlemen agreements.
See part one, here: Land (er, FREQUENCY) Grab. See part three, here: In Response — Can’t We All Just Get Along?
Displaced and Marginalized
There are some unhappy amateur radio operators in the world of shortwave operations. Users of Morse code, and digital modes other than the highly-popular modes engineered by Joe Taylor, K1JT, feel displaced on the many amateur radio bands where Joe’s wildly-popular mode FT8 has erupted.
Joe (born March 29, 1941), is a friend of hams everywhere, and is an American astrophysicist and Nobel Prize in Physics laureate (https://g.nw7us.us/2Ptquv1) for his discovery with Russell Alan Hulse of a “new type of pulsar, a discovery that has opened up new possibilities for the study of gravitation.”
Many have asked questions like, “Did Joe Taylor K1JT Destroy Amateur Radio? Did Joe Taylor K1JT, Nobel Laureate and noted friend of hams everywhere, accidentally destroy amateur radio?” This question remains relevant, even as more and more FT8 operators take to the HF bands to chase wallpaper and awards.
FT8 Has Validity and Usefulness
Full disclosure: I administer a Facebook group for FT8 and FT8-related modes, because I believe that the mode has a valid place in our amateur radio technology portfolio. Here is the Facebook group URL, if you would like to join the fun: https://www.facebook.com/groups/FT8.FT4.HF.6m/. Understand, I have used and will continue to use FT8.
Because it has a place, it stands to reason that everyone should become more aware of the impact of using FT8 on the bands. It also stands to reason that it should be used ethically, and in the best spirit of amateur radio.
Many amateur operators use the FT8 digital mode as a novelty when there isn’t much else happening on amateur radio shortwave bands. One of the great things about it is that you can tell when a band is open–even though you don’t hear any other signals of other modes on the band in question, you very well may hear the roar of FT8 on the band where propagation actually exists to somewhere else than your QTH.
Others use it to finally get their DXCC, or WAS, or other award and wallpaper. This is especially popular during this season of the sunspot cycle where there are no sunspots–propagation is limited to lower-HF amateur bands because there’s just not enough solar activity to energize the ionosphere enough to open up the higher segment of shortwave.
FT8 Has Limitations
Can FT8 be used for two-way conversations? No. However, the JS8CALL digital mode is designed from the FT8 mode, by changing the protocol in a way that allows free text. It is designed for ragchewing and the new version 2.0 offers three modes of chat with 50 Hz and 16 wpm, 80 Hz and 24 wpm, and the turbo mode at 160hz and 40wpm with turbo only having a 6-second turn around time. The designated frequency is 7.078, which many find much nicer to use.
However, many find JS8CALL combersome, and non-intuitive. How fast and how reliably can it handle critical messages, say, during an emergency? I’m sure the software will improve, but how good is the protocol?
A mode such as Olivia has been field proven, and time tested. It can reliably handle traffic.
The Rant
During the early days of widespread FT8 operation that came with the first public non-Beta release of FT8-equipped WSJT-X software, I tried to reason with the FT8 development leadership team. I made a polite attempt at explaining how incredibly rude they were in purposefully programming into the software the default operating frequencies such as 7.075, 14.075, and so on.
One of the main leaders of that team slammed me and stated that “we only suggested those frequencies; the operator is free to change them.” Additionally, he stated that the team used a common QSO/Mode spotting website to see what digital modes or other operations (like CW) were sparser. They perceived that the frequencies they proposed where no longer active because they saw few if any spots. They thought that no one would care.
I explained that a single website-spotting strategy was illogical and very lazy. This is true for several reasons, at least.
I guess you have to have a Ph.D. to know better than any average ham who went by gentleman’s agreements. I have an extremely dim view of JT and his disciples. CW is not the only operating group he’s engineered out of traditional slices of spectrum. Olivia, and other modes, now have been pushed down into PSK subbands, and everyone is feeling the crowding. As far as my thinking of FT8, well, it is radio, but it doesn’t foster goodwill and building serious communications skill. IMHO.
Play Nice, Be Positive and Polite. Smile.
I’ve received wise counsel from a number of fellow amateur radio operators. They implore us to not promote hostility between “us and them.” That even though the WSJT team is playing the playground bully, we should not be vengeful, but polite and willing to negotiate in good faith.
If we don’t play nice with the bully then the bully won’t play with us. And, the general public will side with the bully because the bully has the nice toys…
Good negotiations, though, take a willingness by both sides, so that conversation evolves, resulting in positive, cooperative actions embraced by both parties. There are other amateur radio operators who have made attempts to open up talks with Joe and crew. What are the results, so far?
We can hope that Joe Taylor and his group of developers and leadership take a proactive role and join a conversation that is with a wider group of amateurs than just the WSJT enthusiasts. We hope that they will play fairly, and cooperatively, with the rest of the amateur radio community.
