A G1 geomagnetic storm is ongoing, with G2 conditions possible during the next 24 hours. A NOAA G1 watch is in effect for the 24th.

The DST index (purple line on the chart in the 2nd image) which measures the ring of charged particles (ions and electrons) flowing around Earth, is now undergoing rapid charging and is at -37nT.

HF radio degradation is likely in polar regions. GPS signals may suffer degradation at high and polar latitudes.

The sun has become more active this week as a series of minor flares begins raising the solar flux.

The solar wind speed has been very slow but speed and density have increased in the last few hours due to the passage of some coronal holes. Minor shocks have been observed.

A G1 geomagnetic storm watch is in effect for tomorrow due to increased activity from the coronal holes.

#Sun Undergoing Mysterious Change, Nobody Knows Why
#Astronomers discovered #magnetic activity in Sun is being squeezed into more tightly confined area under isurface, which has implications for #spaceweather forecasts and #heliophysics.
Using new tools, astronomers discovered a weird mismatch in surface and p-mode signals that emerged more than a decade ago and has become especially pronounced in the current epoch, Cycle 25, which began in 2019.
