Solar Activity
Solar activity reached high levels. The largest event was an X2.0/3b flare (R3-Strong) at 31/2120 UTC from Region 3878 (N16E23, Eki/beta-gamma-delta). In addition, seven M-class flares (R1-Minor) were observed from Regions 3875 (N28W41, Dai/beta), 3876 (S06W46, Dki/beta-gamma), and 3878. Growth was observed in Regions 3875 and 3876, and new Region 3880 (S13E55, Axx/alpha) was numbered. The remaining regions were either stable or in decay. Analysis of a CME associated with flaring from Region 3877 (S16W04, Axx/alpha) at around 31/1252 UTC resulted in a possible glancing blow on 03 Nov. .Forecast... M-class flares are expected, with a chance for X-class flares, through 03 Nov.
Solar Wind
Enhanced solar wind conditions prevailed through much of the period, with an increase in interplanetary magnetic field observed late in the day. Total field strength reached 9 nT and the Bz component reached -8 nT. Solar wind speeds ranged between 450-600 km/s. The phi angle was predominately negative.
Energetic Particle
The greater than 10 MeV proton flux persisted at S1 (Minor) levels throughout the period. The greater than 2 MeV electron flux was at normal to moderate levels.
