SOLAR CYCLE 25 ACTIVITY REPORT APRIL 15_2023
Solar activity has been at moderate levels for the past 24 hours. AR3282 (N11E52) produced two M-class solar flares
● M1.1 event observed at 16:18 UTC on April 14 it caused a minor R1 radio blackout over Central and South America.
● M1.6 event observed at 23:27 UTC on April 14 it caused a minor R1 radio blackout over South Pacific Ocean
There are currently 9 numbered sunspot regions on the solar disk: AR3272, AR3273, AR3275, AR3276, AR3278, AR3279, AR3280, AR3281, AR3282 AR3277 is gone
The total number of sunspots has decreased to 153 (74 of these are grouped into 9 active regions) NOAA forecasts for the next 24h: 99% chance for C flares, 40% chance for M flares and 5% chance for X flares.

SOLAR CYCLE 25 ACTIVITY REPORT APRIL 16_2023
Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C7 event observed at 09:14 UTC from Region 3282 (N11E43, 400MH, beta )
There are currently 8 numbered sunspot regions on the solar disk: AR3272, AR3273, AR3275, AR3276, AR3279, AR3280, AR3281, AR3282, AR3278 is gone
The total number of sunspots has decreased to 151 (71 of these are grouped into 8 active regions) NOAA forecasts for the next 24h: 99% chance for C flares, 50% chance for M flares and 10% chance for X flares.
AR3280 (N07W48) continues with an beta-gamma magnetic configuration while its size has grown to 240MH. AR3280 harbors energy for M-class solar flares.
AR3281 (S24E44) has developed a beta-gamma magnetic complexity with an area of 310MH. This sunspot is on the southeast and next week it will be facing the Earth, unlike AR3280, which will leave the solar disk this weekend. AR3282 harbors energy for M-class solar flares.
Both regions changed NOAA's forecast regarding the possibility of M-class solar flares.

I also wondered where these shockwaves came from.
I don't remember any big flares or CMEs in the last 3 days and we're not really in a high speed steam either(?) Maybe from the occasional M-class flares that we had.
According to SpaceWeather
Spaceweather.com Time Machine

But It is too early for it to generate shockwaves. It is a mystery.
I already asked about the high proton density to the experts. I hope they want to answer.
SOLAR CYCLE 25 ACTIVITY REPORT APRIL 17_2023
Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C9 event observed at 17:44 UTC on April from a unnumbered sunspot.
There are currently 9 numbered sunspot regions on the solar disk: AR3272, AR3273, AR3275, AR3276, AR3279, AR3280, AR3281, AR3282 and new region AR3283
The total number of sunspots has increased to 155 (65 of these are grouped into 9 active regions) NOAA forecasts for the next 24h: 99% chance for C flares, 50% chance for M flares and 10% chance for X flares.
AR3280 (S08W69) continues with a beta-gamma magnetic configuration, however its size has decreased to 200MH ON the other hand, AR3281 (S24E31) Continues with a beta-gamma magnetic configuration with an area of 300MH. So far both regions have only produced C-class solar flares.
● Auroral Activity
The geomagnetic field has been at quiet levels for the past 24 hours. According to SpaceWeatherlive, solar wind speed reached a peak of 1196 km/s at 00:34 UTC on April 16 Maximum planetary index Kp 2
It is quite possible that this VERY high speed solar wind is the cause of a very high proton density per cubic centimeter that was recorded yesterday.
These were some of the other density peaks recorded yesterday
At around 04:40 UTC 50 p/cm³ then it dropped to 0.42 p/cm³
At around 05:30 UTC 100 p/cm³ was recorded, then it dropped to 24.63 p/cm³.
At around 00:00 UTC on April 17 50 p/cm³ then it dropped to 6.71 p/cm³ at 02:11 UTC
These peaks were observed by other users of the DSCOVR spacecraft measurements.
I did not hear back from the experts I asked about this phenomenon. In SpaceWeatherlive a user answered that it was due to a bug in the DSCOVR system.
Commonly, the solar wind density graph looks like this
After geomagnetic storms, the density may go to zero, not rise, as well as the neutron count.
According to NOAA
SPE may also come from cosmic rays from the Galaxy.
In my opinion this phenomenon was not due to a bug in DSCOVR this happened because of the speed that the solar wind reached or it has an extrasolar origin.

A magnificent shot of a 100,000 km high plasma fountain from an amateur astronomer
Argentine amateur astronomer Eduardo Schaberger took a magnificent picture of the solar prominence of the polar crown, which was 100,000 km high.
The plasma is in motion under the influence of the magnetic field that ejected it, and it is sent back at a speed of about 36,000 km/h. Scientists still cannot explain all the mechanisms of this phenomenon.
Prominences are huge plasma emissions from the surface of the Sun, which can reach heights of up to several hundred thousand kilometers. They are formed as a result of magnetic disturbances in the Sun, which lead to the exit of magnetic lines from the surface and the formation of local magnetic fields. Under the influence of these fields, the plasma begins to move along them and form prominences.
Despite the fact that scientists have been studying prominences for a long time, the mechanisms of their formation and evolution are still not fully understood. One of the main problems is the complexity of modeling magnetic fields in the Sun and their interaction with plasma. In addition, prominences can interact with each other and with the surrounding plasma, which also complicates their study.

Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C3.6 event observed at 09:22 UTC on April 20 from Region 3281 (S23W22).
There are currently 6 numbered sunspot regions on the solar disk: AR3276, AR3279, AR3281, AR3282, AR3283, AR3284
The total number of sunspots has decreased to 97 (37 of these are grouped into 6 active regions) NOAA forecasts for the next 24h: 99% chance for C flares, 35% chance for M flares and 1% chance for X flares.All regions now have stable magnetic fields.
● Auroral Activity
The geomagnetic field has been at quiet to unsettled levels for the past 24 hours, solar wind speed reached a peak of 1083 km/s (Very high speed, recorded by DSCOVR spacecraft) at 05:45 UTC on April 20
Maximum planetary index Kp 3
At 03:16 UTC on April 21, a new high density peak of the solar wind was recorded, reaching 116.56 protons/cm³ At 03:50 the density is 3.92 p/cm³. This coincides with the peak solar wind speed mentioned above.
Coronal holes are known to be responsible for high velocity solar winds... but there are no significant coronal holes facing the Earth at this time... so what is going on? What source is sending us a high velocity solar wind stream?
Aurora Oval Bz: 4.19 nT North
● Current Conditions at 04:00 UTC on April 21
▪︎ Geospace unsettled
▪︎ Geomagnetic conditions now : Kp 3
▪︎ Solar wind speed record: 383.2 km/sec (Normal speed)
▪︎ density: 2.71 p/cm³ (low density)
▪︎ Neutron Counts today: -2.1% (Below Average)
▪︎ X-ray Solar Flare: C2 at 22:30 UTC
▪︎ Sunspot number: 97 (SN 124 April 20)
▪︎ Spotless Days 2023 total: 0 days (0%)

SOLAR CYCLE 25 ACTIVITY REPORT APRIL 22_2023
Solar activity has been at moderate levels for the past 24 hours. The magnetic filament eruption coincided with an M-class flare from region 3283. The M1.7 occurred at 18:12 UTC on April 21 from active region 3283 (S22W18) it caused a minor R1 radio blackout over North America.
There are currently 7 numbered sunspot regions on the solar disk: AR3276, AR3279, AR3281, AR3282, AR3283, AR3284 and new region AR3285
The total number of sunspots has increased to 114 (45 of these are grouped into 7 active regions) NOAA forecasts for the next 24h: 99% chance for C flares, 35% chance for M flares and 1% chance for X flares.
AR3282 has again developed a beta-gamma magnetic field and its size is 410MH. The region is located in the northwest (N11W42) and will leave the solar disk this weekend.
● Auroral Activity
The geomagnetic field has been at quiet to unsettled levels for the past 24 hours, solar wind speed reached a peak of 514 km/s (Moderately high speed) at 20:36 UTC on April 21 Maximum planetary index Kp 3
Aurora Oval Bz: 2.33 nT North
● Current Conditions at 05:00 UTC on April 22
▪︎ Geospace quiet
▪︎ Geomagnetic conditions now : Kp 2
▪︎ Solar wind speed record: 397.5 km/sec (Normal speed)
▪︎ density: 1.14 p/cm³ (low density)
▪︎ Neutron Counts today: -1.4% (Below Average)
▪︎ X-ray Solar Flare: C4 at 01:48 UTC

Mystery solved?
I asked three experts about the cause of the very high speed and density in the solar wind recorded in recent days by the DSCOVR spacecraft.
Commonly solar wind speed and density are associated with CMEs or coronal holes, but recent CMEs have been very weak and there are no significant coronal holes. (Until this morning when the magnetic filament event and the M-class solar flare happened).
here is the opinion of Halo CME via inbox on Twitter.
NASA Space Weather Prediction Center shows the peaks also

Perhaps we are reaching some area of space with a higher density of protons, or they are initial waves or nothing as they say.
If people start asking questions maybe they have to make something up.
