Here is the current forecast discussion on space weather and geophysical activity, issued 2018 Jan 31 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. A simple bipolar spot group emerged and was assigned as new NOAA/SWPC Region 2697 (S10E48, Bxo/beta). The region was generally stable, but did produce a B1 flare at 30/1739 UTC. No Earth-directed CMEs were observed in available coronagraph imagery.

Forecast: Solar activity is expected to remain very low, with a slight chance of C-class flares the next three days (31 Jan-02 Feb).

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux was at normal levels and the greater than 10 MeV proton flux remained at background values.

Forecast: The greater than 2 MeV electron flux is expected to continue at normal levels all three days (31 Jan-02 Feb) and the greater than 10 MeV proton flux is expected to maintain background levels.

Solar Wind

24 hr Summary: Solar wind parameters were indicative of a slow solar wind regime. Total IMF strength ranged primarily from 3 to 5 nT and the Bz component underwent mainly weak deviations. Solar wind speed averaged between 325-350 km/s. The phi angle was predominantly positive until near 31/0000 UTC, when it switched to a negative orientation.

Forecast: A slow solar wind regime is anticipated to continue over the next three days (31 Jan-02 Feb).

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to be mostly quiet all three days (31 Jan-02 Feb), with a isolated periods of unsettled conditions likely on day one.

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
