Geophysical report

Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

Joint USAF/NOAA Solar and Geophysical Activity Summary

SGAS Number 364 Issued at 0245Z on 30 Dec 2015 This report is compiled from data received at SWO on 29 Dec
A. Energetic Events
Begin  Max  End  Rgn   Loc   Xray  Op 245MHz 10cm   Sweep
B. Proton Events
The greater than 10 MeV proton flux reached a peak level of 3 pfu at 29/0150 UTC but have since returned to near background levels.
C. Geomagnetic Activity Summary
The geomagnetic field is expected to be mostly quiet for the first portion of day one (30 Dec). Mid to late on day one the anticipated arrival of the 28 Dec CME is expected, likely increasing field conditions to active through severe storm levels. Day two (31 Dec) will likely see minor storm levels early in the day before subsiding CME effects lower field conditions to mostly unsettled to active levels. Day three (01 Jan), is expected to be quiet to active with the arrival of the above mentioned CIR/CH HSS.
