Spaceweather.com ran the following update today:HERE COMES TROUBLE? A big sunspot is emerging over the sun's southeastern limb, and it is crackling with activity. NASA's Solar Dynamics Observatory recorded a surge of extreme ultraviolet radiation from the sunspot's magnetic canopy on March 21st:
This appears to be the return of old sunspot 1165, last seen in early March when it formed on the sun's southwestern limb. Since then it has been transiting the far side of the sun, apparently growing in size and restlessness. The potential for trouble will become more clear in the hours ahead as the active region emerges in full. Stay tuned.

The proton flux is elevated, but not exceeding the threshold. This increase is probably linked with a back sided CME of Mar 21, 02:54UT. The Earth is magnetically connected with the source site behind the Sun. The Parker spiral (the Parker spiral is the shape of the suns magnetic field) has bended magnetic field lines that guide the electrically charged protons. The Earth is near such field lines along which these protons travel. This is a rare event.
