GEOMAGNETIC/SOLAR FIELDS
The geomagnetic field was at quiet conditions today. The AP level was 6. High latitude geomagnetic field saw slightly disturbed conditions with AP at 13. This appears to conclude the current geomagnetic storms and starts the clock on maximum effects on seismicity. A strong increase in global seismicity likely 4 5 days after the geomagnetic storm ends, probably October 19-22. These are most likely 10-15 degrees north or south of the geomagnetic equator and/or at high latitudes under the auroral ionospheric ring currents.
The geomagnetic field is expected to see unsettled conditions October 18 and 19 and quiet October 20. Solar activity is expected to be at quiet conditions October 18-20 with a chance (1%) of an M-class flare and a 1% chance of an X-Class solar flare. A proton storm is possible at 1% probability each of the three days.
