The ARRL Solar Report 

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...

The ARRL Solar Report 

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 Solar Report 

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 Call for Operators and Monitors 2025 

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...

Fram2 Astronaut Conducts First Amateur Radio Contacts from SpaceX Dragon
