The proton flux is rather high at the moment - lets see what happens when it comes back down. Here's a few comments from Lowell's posts about solar and proton storms that I found in the archives: from message 11103: The geomagnetic field remained at quiet conditions today. There were no M- or X-class solar flares observed. A sharp decline in the intensity of the geomagnetic field (Hp) occurred with the maximum reduction at about 00 UT on Nov. 19. This appears to have been related to an enhancement in proton flux which has been increasing gradually throughout the day. High proton flux conditions are often associated with subdued global seismicity, however shortly after the decline and subsequent return to normal a series of mild earthquake occurred in Northern and Central California beginning with a Ml 3.3 near the Geysers. from message 11259: Global and regional seismicity remained relatively quiet through the past 24 hours. As the proton storm wanes and dissipates by tomorrow, and with the arrival of a subsequent CME from today's X1.1 solar flare, these quiet conditions could change to active seismicity. The largest events appear most likely to occur between Nov. 28 - Dec. 1, 2001, if they are triggered by the geomagnetic storms and the two X1.1 flares.
from message 15221: Delayed effects from the recent strong geomagnetic storms were probably important in the timing of the Balkans and the Andreanoff Islands earthquakes today. Strong events often follow X-class solar flares 3-5 days later in sub- and anti-solar regions. The geomagnetic field, however was at quiet conditions today. The proton storm was reaching background proton flux. As this occurs, electrons are more able to form ring currents and associated earthquake triggering often occurs in higher latitudes and along the geomagnetic equator in addition to the areas already under seismic watch conditions from the storms and flares.
