Solar activity has been at low levels with only minor C-class
flaring through April 24, 2025, and is expected to be moderate with
a chance of M-class flares (R1-R2, Minor-Moderate) through April 26.
No Earth-directed Coronal Mass Ejections (CMEs) have been observed.
A southwest CME was observed on April 23 and is considered to be
far-side due to the lack of any on-disk plasma motion/flare
activity.

Spaceweather.com reports a Cannibal Coronal Mass Ejection on April 15 sparked geomagnetic storms.  On April 16, the storm became severe (G4) with Northern Lights sighted as far south as France.  The storm is subsiding now to a category G1/G2, which could still produce high-latitude auroras.

Although Regions AR4062 and AR4064 have been relatively quiet they are more structurally complex than ant...

Due to most of the regions on the solar disk being fairly simple in
their magnetic complexity, solar activity is expected to remain at
low levels with a chance for M-class flares (R1 to R2, or Minor to
Moderate).

Solar wind parameters are expected to trend further towards nominal
levels as the Coronal Hole High-Speed Stream effects continue to
wane.

Additional enhancements from another negative polari...

The ARRL DXCC Desk has determined that the operation by a DXpedition team from Mount Athos meets the DXCC award program’s accreditation criteria. Contacts with the team, which operated in January 2025 using the call sign SV1GA/A, will therefore count toward DXCC. Additionally, due to actions taken by local authorities that resulted in the early termination of the operation, any future operation...

Solar activity is likely to be moderate (R1-R2, Minor-Moderate) with
a slight chance for X-class flares through April 5.

The geomagnetic field is expected to be quiet to minor storm levels
on April 4 and 5.

NOAA Geomagnetic Activity Probabilities for April 5 and 6 forecast a
15% chance, and then a 1% chance, of a Moderate storm for the
reporting period.

The forecast of solar and geomagnetic activity c...

HamSCI, Ham Radio Science Citizen Investigation, is preparing now for a series of meteor scatter (MS) experiments later this year and need amateur radio operators to help.

While the target storms are in August (Perseids) and December (Geminids) preparation and testing is already underway. This is a combination 'special event' and a contest to generate contact data during meteor scatter events u...
