Here is the current forecast discussion on space weather and geophysical activity, issued 2019 May 22 1230 UTC.
Solar Activity
24 hr Summary: Solar activity remained very low. There were no sunspots on the visible disk, and no Earth-directed CMEs were observed in available coronagraph imagery.
Forecast: Solar activity is expected to remain very low on 22-24 May.
Energetic Particle
24 hr Summary: The greater than 2 MeV electron flux was at normal to moderate 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 on 22-24 May. The greater than 10 MeV proton flux is expected to continue at background levels.
Solar Wind
24 hr Summary: Solar wind measurements from DSCOVR were close to background levels. Total field strength was generally less than 5 nT, and Bz was unremarkable. Wind speeds averaged between 350-400 km/s. The phi angle was in a predominately positive orientation until approximately 22/0731 UTC when a SSBC occurred, as phi became negative.
Forecast: Minor enhancements in the solar wind are anticipated on 22 May with a series of weak, recurrent, negative polarity CH HSSs. Near-background conditions are expected to return on 23-24 May.
Geospace
24 hr Summary: The geomagnetic field was quiet.
Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on 22 May as a result of weak, recurrent, negative polarity CH HSSs. A return to mostly quiet levels is anticipated by 23 May, and is expected to continue into 24 May.

Space Weather and Ham Radio YouTube Channel News:
I am working on launching a YouTube channel overhaul, that includes series of videos about space weather, radio signal propagation, and more.
Additionally, I am working on improving the educational efforts via the email, Facebook, YouTube, Tumblr, and other activities.
