Here is the current forecast discussion on space weather and geophysical activity, issued 2018 Feb 24 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. The visible disk remained spotless. No Earth-directed CMEs were observed in available satellite imagery.

Forecast: Solar activity is expected to be very low throughout the forecast period (24-26 Feb).

Energetic Particles

24 hr Summary: The greater than 2 MeV electron flux was at normal to high levels with a peak flux of 2,074 pfu observed at 23/2255 UTC. The greater than 10 MeV proton flux was at background levels.

Forecast: The greater than 2 MeV electron flux is expected to be at moderate to high levels and the greater than 10 MeV proton flux is expected to continue at background levels throughout the forecast period (24-26 Feb).

Solar Wind

24 hr Summary: Solar wind parameters reflected continued, but slow weakening, influence from a negative polarity CH HSS. Wind speeds began the period near 550 km/s, reached a maximum of 564 km/s at 23/1825 UTC and ended the period near 475 km/s. Total field reached a maximum value of 7 nT while Bz component dropped to a period low of -6 nT. Phi angle remained in a predominantly negative orientation.

Forecast: The solar wind environment is likely to remain enhanced over the next three days (24-26 Feb) due to influence from multiple negative polarity CH HSSs in the southwest quadrant of the solar disk. An additional enhancement is expected late on day two (25 Feb) as a polar-connected, negative polarity CH HSS becomes geoeffective.

Geospace

24 hr Summary: The geomagnetic field was at quiet to unsettled levels due to continued effects from negative polarity CH HSS influence.

Forecast: The geomagnetic field is expected to be at quiet to active levels on days one and two (24-25 Feb), with G1 (Minor) storm levels likely on day three (26 Feb) under negative polarity CH HSS influence.

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
