Here is the current forecast discussion on space weather and geophysical activity, issued 2018 Apr 16 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was at very low levels. New Region 2705 (N17W05, Axx/alpha) was responsible for a few B-class flares over the period. The largest was a B3 flare at 15/1240 UTC. No Earth-directed CMEs were observed.

Forecast: Solar activity is expected to be at very low levels with a slight chance for isolated C-class flares over the next three days (16-18 Apr).

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux reached high levels this period with a peak flux of 6,481 pfu at 15/2215 UTC. The greater than 10 MeV proton flux was steady at background levels.

Forecast: The greater than 2 MeV electron flux is expected to reach high levels each of the next three days (16-18 Apr). The greater than 10 MeV proton flux is expected to continue at background levels throughout the forecast period.

Solar Wind

24 hr Summary: solar wind parameters continued at nominal levels with solar wind speed ranging from approximately 290-340 km/s. Total field ranged from 1-5 nT while the Bz component was between +/-3 nT. Phi angle was mostly oriented in a negative (towards) sector.

Forecast: Solar wind parameters are expected to be at or near nominal levels over the next three days (16-18 Apr).

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: Generally quiet conditions are expected to prevail over the next three days (16-18 Apr) under a nominal solar wind regime.

What's the difference between CB & amateur (ham) radio? Here ia a video with an opinion by our curator, Tomas (amateur radio operator, NW7US): Did NCIS TV Show Malign the Amateur Radio Service? https://www.youtube.com/watch?v=pIWJ7kKbxiM?t=1m33s
