Here is the current forecast discussion on space weather and geophysical activity, issued 2018 Mar 06 1230 UTC.

Solar Activity

24 hr Summary: Solar activity remained very low. No Earth-directed CMEs were observed in available coronagraph imagery.

Forecast: Solar activity is expected to be very low throughout the forecast period (06-08 Mar).

Energetic Particles

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 levels.

Forecast: The greater than 2 MeV electron flux is expected to be at normal to moderate levels throughout the forecast period (06-08 Mar). The greater than 10 MeV proton flux is expected to continue at background levels.

Solar Wind

24 hr Summary: Solar wind parameters, as measured by the DSCOVR spacecraft, indicated near-background conditions. Total magnetic field strength ranged between 1-8 nT and Bz was variable over the past 24 hours. Solar wind speeds were mostly between 360-380 km/s. Phi angle was variable with a tendency towards the positive sector.

Forecast: Mostly nominal conditions are anticipated over the next two days (06-07 Mar). Possible weak enhancements in the solar wind from a non-recurrent coronal hole are possible on day three (08 Mar).

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to be at mostly quiet levels on days one and two (06-07 Mar) with mostly nominal solar wind conditions expected to persist. Isolated unsettled periods are possible on day three (08 Mar).

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
