Here is the current forecast discussion on space weather and geophysical activity, issued 2018 Mar 02 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was low. Region 2700 (N08W61) decayed to plage, but still managed a C1 flare at 02/1107 UTC. No Earth-directed CMEs were observed in available coronagraph imagery.

Forecast: Solar activity is expected to remain very low all three days (02-04 Mar).

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux was at normal to moderate levels with a peak flux of 841 pfu observed at 01/1750 UTC. 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 all three days (02-04 Mar). The greater than 10 MeV proton flux is expected to continue at background levels.

Solar Wind

24 hr Summary: Solar wind parameters returned to an ambient solar wind regime. Total field strength ranged primarily from 2 to 5 nT. The Bz component underwent only weak deviations. Solar wind speed decreased from near 400 km/s to 350 km/s. The phi angle was predominantly positive.

Forecast: A nominal solar wind regime is anticipated over the next two days (02-03 Mar). Slightly enhanced conditions are expected on day three (04 Mar) due to weak influence from the extension of the northern polar CH HSS.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to remain primarily quiet on days one and two (02-03 Mar) under a nominal solar wind. Quiet to unsettled conditions are expected on day three (04 Mar) due to weak influence from the extension of the northern polar CH HSS.

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
