Get to know the local repeaters this November

The Puget Sound Repeater Roundabout is a weekend-long event held on many of our local repeaters. The goal is to meet new people and work repeaters you might not usually key up. Light up the airwaves and make some noise on the great repeaters in the Puget Sound area!

The Puget Sound Repeater Roundabout will begin on November 19th, 2022, at 00:00, and end on November 20th, 2022 at 23:59, Pacific time.

Anyone with a ham radio license can participate! You don’t even have to be local; stations may participate over Echolink or Allstar if they are available.

Repeaters Only these 109 participating repeaters from 48 radio groups are eligible for scoring points in the Repeater Roundabout. Please stick to these repeaters; we don’t want to annoy anyone who did not want to bring the contest to their repeater.”

For complete details visit:  http://www.repeaterroundabout.com/ . This is an excellent opportunity for hams of all ages and license class to experience a contest on six meters and up repeaters. Every ham is invited and encouraged to participate whether you have a $30 handheld or a $3,000 base/mobile radio.

Thank you, Puget Sound Radio Group, for this awesome get on the air opportunity.

“Ten meters is getting so [much] better that today, on November 9 at 1319 UTC, [I] had a contact with 3B9FR on 28.522 MHz up 5. He even answered me in Spanish.”

3B9FR was operating from Rodrigues Island in the Indian Ocean, which is more than 9,000 miles from Puerto Rico.

Because ARRL is closed this Friday for Veterans Day, the regular Friday bulletin will not come out until Monday, November 14. Sunspot numbers for November 3 through 9, 2022, were 65, 81, 82, 78, 80, 85, and 81, with a mean of 78.8. The 10.7-centimeter flux was 125.3, 117.7, 131.1, 130.8, 134.6, 132.3, and 137.6, with a mean of 129.9. Estimated planetary A indices were 26, 16, 10, 4, 19, 12, and 7, with a mean of 13.4. Middle latitude A index was 16, 12, 8, 3, 12, 8, and 8, with a mean of 9.6.

Weekly Solar Report

Tad Cook, K7RA, of Seattle, Washington, reports for this week’s ARRL Propagation Bulletin:

Solar activity perked up this week. The average daily sunspot number rose from 58.4 to 70.3, and solar flux averages increased from 113.3 to 129.9.

There are still problems with the Fredericksburg magnetometer, so I did my own rough estimate of middle-latitude numbers. I wish I could substitute the Boulder numbers, but I cannot find a source for the data outside of purely graphic representations.

https://www.swpc.noaa.gov/products/station-k-and-indices

Planetary A index averages went from 19.4 to 13.7, and middle latitude estimated numbers changed from 9.1 to 12.6.

The solar flux prediction shows the highest values over the next week, starting with 130 on November 3 – 4; 135, 130, 135, 130, and 135 on November 5 – 9; 115 on November 10 – 12; 112 on November 13 – 14; 110 on November 15; 108 on November 16 – 18; 104 on November 19; 100 on November 20 – 23; 98 on November 24 – 25; 100, 105, 105, and 110 on November 26 – 29; 112 on November 30 through December 2, and 118 on December 3 – 6.

Predicted planetary A index is 12 on November 3 – 4; 20, 15, and 8 on November 5 – 7; 5 on November 8 – 9; 18, 18, and 15 on November 10 – 12; 5 on November 13 – 17; 25, 15, and 8 on November 18 – 20; 5 on November 21 – 22; 8, 15, and 25 on November 23 – 25; 15 on November 26 – 27; 18, 12, 10, 12, 20, and 15 on November 28 through December 3, and 5 on December 4 – 6.

Sunspot numbers for October 27 through November 2, 2022, were 72, 87, 97, 68, 56, 63, and 49, with a mean of 70.3. The 10.7-centimeter flux was 129.7, 129.3, 133.9, 130.5, 127.9, 128.1, and 129.7, with a mean of 129.9. Estimated planetary A indices were 9, 16, 26, 12, 11, 8, and 14, with a mean of 13.7.

Tad Cook Solar Report

Tad Cook, K7RA, of Seattle, Washington, reports for this week’s ARRL Propagation Bulletin:

Sunspot activity seems listless. Average daily sunspot numbers went from 57.3 to 58.4 (see note at the end of the bulletin concerning last week’s averages) while solar flux went from 119.6 to 113.2.

The middle latitude geomagnetic numbers this week seem wrong. See what I mean.

The middle latitude numbers presented here are my own estimates,

trying to correlate with the high latitude and planetary numbers.

Average daily planetary A index went from 18.6 to 10.4, and middle latitude numbers from 8.1 to 9.1.

Predicted solar flux is 120 on October 27; 118 on October 28 – 30; 114 from October 31 through November 2; 112 on November 3 – 5; 118 on November 6 – 9; 115 on November 10 – 12; 112 on November 13 – 14; 110 on November 15; 108 on November 16 – 18; 104 on November 19; 100 on November 20 – 23; 98 on November 24 – 25; 100 on November 26, and 105 on November 27 – 28.

So, the rise in solar flux to 160 in the first week of November presented in the previous two bulletins seems to be gone from the current prediction.

Predicted planetary A index is 10, 14, 18, 22, and 16 on October 27 – 31; 12, 12, and 8 on November 1 – 3; 5 on November 4 – 9; 18, 18, and 15 on November 10 – 12; 5 on November 13 – 17; 25, 18, 17, and 12 on November 18 – 21; 5 on November 22 – 23, and 8, 15, and 20 on November 24 – 26.

Forbes on doomsday flares.

Tabloid news on flares.

In last week’s bulletin, ARLP042, the averages were wrong.

The correct averages for the numbers at the end of the bulletin in ARLP042 were 57.3, 119.6, 10.6, and 8.1 for sunspot number, solar flux, planetary A index, and middle latitude A index, respectively. The wrong numbers were actually from the previous week.

Sunspot numbers for October 20 through 26, 2022, were 33, 60, 55, 65, 46, 72, and 78, with a mean of 58.4. The 10.7-centimeter flux was 115.8, 109.4, 105, 108.4, 114.8, 116.3, and 122.4, with a mean of 113.2. Estimated planetary A indices were 7, 5, 27, 16, 8, 5, and 5, with a mean of 10.4. Middle latitude A index was 5, 4, 24, 15, 7, 5, and 4, with a mean of 9.1.

Solar Report

Tad Cook, K7RA, of Seattle, Washington, reports for this week’s ARRL Propagation Bulletin:

Sunspot activity took quite a plunge over this reporting week (October 13 – 19). Average daily sunspot numbers declined from 114.9 to 57.3, while equivalent solar flux values went from 155.3 to 119.6.

Geomagnetic indicators were slightly lower, with the average planetary A index going from 13.3 to 10.6, and middle latitude A index from 10.4 to 8.1.

I should note that the middle latitude A index for October 18 – 19 are my own estimates. The Fredericksburg, Virginia, magnetometer was offline for a 24-hour period spanning both days.

The Wednesday forecast of solar flux shows a peak at 160 during the first week in November.

Predicted daily flux values are 110 on October 20 – 26; 115 and 150 on October 27 – 28; 155 on October 29 – 30; 152 on October 31; 160 on November 1 – 8; 150, 140, and 135 on November 9 – 11; 130 on November 12 – 13; 135 on November 14; 138 on November 15 – 17, and 140 on November 18 – 21.

Predicted planetary A index is 12 and 10 on October 20 – 21; 5 on October 22 – 23; 10, 5, 8, and 12 on October 24 – 27; 15, 12, and 20 on October 28 – 30; 15 on October 31 through November 1; 18, 15, 12, 20, and 8 on November 2 – 6; 5 on November 7 – 9; 18 on November 10 – 11; 15 and 8 on November 12 – 13; 5 on November 14 – 15; 12 on November 16 – 17; 8 on November 18, and 5 on November 19 – 21.

Despite the lower solar activity, worldwide 10-meter propagation has been very good this week, probably helped by seasonal variations as we head deeper into the fall season.

In Friday’s bulletin, expect reports from readers.

Sunspot numbers for October 13 through 19 were 57, 51, 50, 59, 84, 50, and 50, with a mean of 114.9. The 10.7-centimeter flux was 130, 120.5, 115.1, 119.2, 125.6, 113.9, and 113.2, with a mean of 155.3. Estimated planetary A indices were 5, 18, 18, 16, 6, 6, and 5, with a mean of 13.3. Middle latitude A index was 4, 16, 15, 11, 4, 4, and 3, with a mean of 10.4.
