SPECIAL NOTE
Syzygy; Solar Proton and Electron Events
For a National Geographic discussion of "syzygy" and earthquakes, see http://news.nationalgeographic.com/news/2005/05/0523_050523_moonquake_2.html
From NOAA "Weekly" solar event definitions for protons and electrons:
Proton Events
A proton event starts when the integrated proton flux (5-minute average) rises above a specific threshold for at least three points. The two alert thresholds are: >10 MeV ³10 p.f.u. and >100 MeV ³ 1 p.f.u. (1 p.f.u. = particle cm-2s-2s-1sr-1 ). The time of maximum is the time tag of the 5 minute averaged flux value that has the greatest value.
Electron Events
An electron event begin is defined as when the greater than 2 MeV GOES electron flux exceeds 1 x 103 pfu level in a day when no values on the previous day were above that threshold. The event continues for each subsequent day where the flux meets or exceeds the threshold. Event end occurs when a complete UT day passes where the electron flux never meets the threshold.
Comments or questions are welcome.
