The CME associated with the M1 flare on October 9, 2021 arrived early on October 12, UTC day, as expected.
“The CME shock front reached the DSCOVR spacecraft (one million miles from Earth) at 12/0147 UTC (October 11 / 9:47 p.m. EDT) when the solar wind speed increased by almost 100 km / s and the entire interplanetary magnetic field ( IMF.) Increased) strength quickly increased to over 15 nT.
“The geomagnetic activity increased as expected with the arrival of the CME and storm conditions G1-G2 (low-moderate) were met.
“The CME progress remains fluid at this point and a G2 clock still applies for the remainder of October 12 and a G1 warning lasts until 10:00 p.m. UTC (6:00 p.m. EDT).”
