LOOK! UP IN THE SKY! WHAT IS IT?

About that title today,  Look! Up in the sky!  What is it?   Nope, not Superman.  I'll start with our sun.  A massive  geomagnetic solar storm  was supposed hit Planet Earth on April 14.    So what happened ? A G2 (Moderate) geomagnetic storm began at 12:45 pm EDT (1645 UTC) on 14 April, 2022. G1 (Minor) storm levels first occurred earlier, at 7:59 am EDT (1159 UTC). This activity is associated with the anticipated arrival of an 11 April coronal mass ejection (CME). The CME arrived at the NOAA DSCOVR spacecraft, about 1 million miles from Earth, early on 14 April. While an interplanetary shock ahead of the CME was not clearly observed, total interplanetary magnetic field (IMF) strength gradually intensified to 20 nT and the Bz component (magnetic field orientation) turned into a prolonged, pronounced southward direction. Enhanced solar wind conditions continue to show the potential for elevated geomagnetic responses to the G1-G2 levels and Watches remain in effect for 14-15 April.
