SOLAR CYCLE 25 ACTIVITY REPORT JUL 16
Solar activity has been at moderate levels for the past 24 hours. Lots of minor C flares. The largest solar event of the period was a M1.1 event peaking at 06:28 UTC july 16 from Region 3057 (N15E04) the flare generated a minor R1 Radio blackout over Central Asia, no CME associated.
However the main event of the past 24 hours was caused by the eruption of the large filament in the northern hemisphere.
There are currently 6 numbered sunspot regions on the disk: AR3053, AR3055, AR3056, AR3057, AR3058 and new region AR3059. Sunspots AR3053 and AR3056 will leave the solar disk in the coming hours
AR3059 is a group of two sunspots located on the southeast (S07E71) with a size of 180MH and a beta magnetic field. The probability of generating C-class eruptions is 35%.
▪︎Auroral Activity
The geomagnetic field has been quiet for the past 24 hours. (KP=3 at 02:04 july 16) Solar wind speed reached a peak of 570.7 km/s at 00:32 UTC july 16 with a density of 12.96 p/cm3
Current Conditions at 13:51 UTC July 16
▪︎Geospace quiet
▪︎Geomagnetic conditions now KP=2
▪︎Solar wind speed record: 266.1 km/sec
▪︎density: 9.81 protons/cm3
▪︎Neutron Counts today: 1.8% Elevated
▪︎Sunspot number: 141 (SN 133 Jul 15)
▪︎There are no significant coronal holes on the Earthside of the sun

Solar activity has been at low levels for the past 24 hours.
There are currently 6 numbered sunspot regions on the disk: AR3059, AR3060, AR3062, AR3063, AR3064, AR3065 and new region AR3066
AR3066 is a group of 3 sunspots located on the southeast (S17E23) with size 10MH and a beta magnetic field
All of them have stable magnetic fields that pose little threat for strong solar flares
The number of total sunspots has decreased to 80.

SOLAR CYCLE 25 ACTIVITY REPORT JULY 26
Solar activity has been at very low levels for the past 24 hours. The largest solar event of the period was a C1 event observed at 08:33 UTC on July 25th
There are currently 6 numbered sunspot regions on the disk AR3060 is gone but AR3059, AR3062, AR3063, AR3064, AR3065, AR3066 remain. (About to lose AR3059 and AR3063 regions over the W limb in the next few hours)
The total number of sunspots has increased to 100 due to new regions appearing on the east side that have yet to be numbered.

COSMIC RAY UPDATE: Cosmic rays in the atmosphere are rapidly subsiding. In the past year alone, radiation levels in the air high above California have plummeted more than 15%, according to regular launches of cosmic ray balloons by Spaceweather.com and Earth to Sky Calculus. The latest measurement on July 23, 2022, registered a 6 year low:
This development, while sudden, is not unexpected. Cosmic rays from deep space are repelled by solar activity; when one goes up, the other goes down. Since 2021, Solar Cycle 25 has roared to life faster than forecasters expected. The onset of the new solar cycle has naturally led to a decrease in cosmic radiation reaching Earth.
To many readers this may sound counterintuitive. After all, don't solar flares produce radiation? Yes, but most high-energy radiation doesn't come from the sun; it comes from deep space. Every day galactic cosmic rays from distant supernova explosions pass through the Solar System. When they hit the top of Earth's atmosphere, they create a secondary spray of radiation, which we measure using sensors onboard our balloons.
The sun makes it more difficult for these cosmic rays to reach Earth. Simply put, when the sun is active, its magnetic field gets stronger and more tangled. Cosmic rays have trouble penetrating the magnetic thicket. Also, individual CMEs sweep aside cosmic rays, causing sharp reductions called "Forbush Decreases." The two effects blend together to bring daily radiation levels down.
