Weekly Commentary on the Sun, the Magnetosphere, and the Earth’s
Ionosphere – January 11, 2024 from OK1HH:

“Since the beginning of the 25th Solar Cycle (December 2019), we
observed 782 sunspot groups, and almost half of them (361) last
year. Most forecasters believe that the solar maximum will occur in
2024.

“The exception is the Bureau of Meteorology Australian Space Weather
Forecasting Centre, whose ‘OBSERVED AND PREDICTED SOLAR INDICES’ table, published on January 4, already showed the probable highest SMOOTHED SUNSPOT NUMBER = 126.4 last November.

“It should fall further until R = 15.5 in December 2029. But I
believe solar activity will continue to rise and that we have a
second maximum ahead of us, no later than 2025.

“Now there is usually at least one active region on the Sun with an
unstable magnetic field ‘beta-gamma,’ capable of producing flares of
moderate magnitude, possibly with CMEs.

“Any large flares would be the exception, and proton flares would be
even more of an exception.

“Among the more significant moderate-magnitude eruptions accompanied
by CMEs is the M3.8/2n class event of 4 January at 0155 UTC, which
produced the Dellinger event (SWF or Shortwave Fadeout) over
Australia and the surrounding Pacific Ocean. There was silence at
frequencies below 20 MHz for more than 30 minutes. This flare took
place in the northeastern solar disk (N04E39), while the CME missed
the Earth.

“Other developments on the Sun were quieter, which contributed to a
relatively long interval of geomagnetic quiet since 4 January
onwards. At the same time, the intensity of solar radiation
increased. The result was progressively improving shortwave
propagation. But seven major active regions can now be counted on
the Sun’s far side. Once they emerge onto the solar disk the
situation will change.”

Sunspot numbers for January 4 through 10 2024 were 64, 121, 149,
171, 152, 183, and 183, with a mean of 146.1. 10.7 cm flux was
125.8, 152.7, 159.4, 167.1, 176.2, 175.9, and 186, with a mean of
163.3. Estimated planetary A indices were 6, 5, 3, 3, 4, 6, and 7,
with a mean of 4.9. Middle latitude A index was 5, 4, 2, 3, 4, 5,
and 7, with a mean of 4.3.

Solar report 1/5/24

Only four new sunspot groups emerged over the past week: one on December 28, 2023, another on December 31, and two more on January 2 and 3, 2024.

Solar indices sank. The average daily sunspot number declined from 114.4 to 63.4, and the average daily solar flux declined from 172.6 to 141.9.

Average daily planetary A index rose from 8.4 to 6.7, and middle latitude numbers rose from 4 to 5.1.

Predicted solar flux over the next few weeks looks moderate. It will be 145 on January 4 – 5; 150 on January 6 – 8; 155 on January 9; 160 on January 10 – 11; 155 on January 12 – 14; 160, 165, 160, and 155 on January 15 – 18; 150 on January 19 – 21; 145 and 140 on January 22 – 23, and 135 on January 24 – 26.

Predicted planetary A index is 8 on January 4; 5 on January 5 – 7; 10 on January 8 – 10, and 5 on January 11 – 26.

Solar activity looks soft as of late, but perhaps we will see a double peak during this cycle.

See an illustration comparing progress in the current cycle to the last cycle, month by month since each solar minimum, at: https://bit.ly/4aMBefh. The second chart from the top of the page is labeled “Solar Cycle Comparison.” The red line is the last cycle, and it was probably smoothed by monthly averages. The darker blue-green line is probably a conventional moving average with the points on the line smoothed over a year. The yellow line is the current cycle — also probably smoothed over a year — and the lighter blue-green line is the current cycle, which was probably smoothed with monthly numbers. This data looks promising for future activity.

Sunspot numbers for December 28, 2023, through January 3, 2024, were 83, 92, 48, 55, 44, 59, and 63, with a mean of 63.4. The 10.7-centimeter flux was 146.7, 142.9, 139.7, 146.2, 135.7, 142.1, and 140.2, with a mean of 141.9. Estimated planetary A indices were 3, 6, 5, 4, 10, 8, and 11, with a mean of 6.7. Middle latitude A index was 2, 6, 4, 2, 6, 8, and 8, with a mean of 5.1.

12/29/23 Solar report

The recent reporting week, December 21-27, saw counter-intuitive solar numbers, with solar flux rising but sunspot numbers in decline. This happens from time to time.

Average daily sunspot numbers declined from 137.4 to 114.4. Only three new sunspot groups emerged, two on December 22, and one on December 27. On Thursday, December 28 one more sunspot emerged and the sunspot number increased from 78 to 83.

Average daily solar flux rose from 162.7 to 172.6.

Predicted solar flux over the next month is 145 on December 29-30, 140 on December 31 to January 1, 2024, 135 on January 2-4, 150 on January 5-7, 155 on January 8-11, then 150, 155, 160, 170 and 175 on January 12-16, 180 on January 17-21, then 170, 165, 162, 155 and 145 on January 22-26, then 140 on January 27-30, and 150 on January 31 to February 3.

Predicted planetary A index is 5, 10, 8, 16, and 8 on December 29 through January 2, 2024, then 5 on January 3-7, then 10, 10 and 8 on  January 8-10, then 5 on January 11-25, then 12, 10, 10 and 8 on January 26-29, and 5 on January 30 through February 3.

Weekly Commentary on the Sun, the Magnetosphere, and the Earth’s Ionosphere, December 28, 2023 from F. K. Janda, OK1HH.

“There are active regions on the Sun that may not even be large, but whose magnetic configuration points to the possibility of solar flares, up to moderately important ones. CMEs are no exception, but they may not hit the Earth at all.

“On December 24, three moderate-importance flares were observed. At least one of them produced a CME. Based on measurements of its velocity, the collision with Earth was predicted to December 27. However, nothing happened, and despite the extension of the prediction of the onset of the disturbance by a day, calm continued on 28 December.

“For many days now there has been such a large active region on the Sun’s far side that it is affecting the vibration of the entire Sun. In addition, it has been observed by NASA’s Mars Perseverance rover camera. While it is primarily designed to see if there is dust in the air, it can see large sunspots and, most importantly, the sun’s far side is now visible from Mars.

“So we await the return of AR 3514, which will rise in the northeastern solar disk shortly after the New Year. It will be a significant contributor to the further rise in solar activity in the days ahead. Furthermore, longer term forecasts are calling for high solar activity in the second half of January. So perhaps we will finally see an improvement in shortwave conditions.”

Don’t forget ARRL Straight Key Night is this weekend, for all of New Years Day (UTC), so that starts at 4:00 PM Sunday here on the Left Coast where I live. Operate CW in a casual event using your straight key or semi-automatic bug.

Solar Report 12/22/23

The winter solstice (the shortest day of the year in the Northern Hemisphere) will occur at 0327 UTC on December 22, 2023. This also marks the start of the summer solstice in the Southern Hemisphere.

Solar activity increased over the last reporting week of December 14 – 20 with 11 new sunspot groups emerging.

One new sunspot group appeared on December 15, four more on the following day, another on December 17, three more on December 18, and two more on December 19 – 20.

The average daily sunspot number rose from 110.3 to 137.4, and the solar flux rose from 129.8 to 162.7. The planetary A index increased from 5.6 to 18.4, and the middle latitude A index grew from 4.6 to 13.7.

The most active day was Sunday, December 17, when the planetary A index was 36, and Alaska’s college A index was 88. Spaceweather.com reported the cause was from the strongest flare of the current solar cycle, an X2.8 class, and it caused a radio blackout.
