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...
