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 363 Issued at 0245Z on 29 Dec 2015 This report is compiled from data received at SWO on 28 Dec

B. Proton Events
The greater than 10 MeV proton flux saw a slight enhancement (below S1-Minor levels) and remained slightly enhanced at the end of the reporting period.
C. Geomagnetic Activity Summary
The geomagnetic field is expected to be quiet to unsettled for day one (29 Dec) and into the first part of day two (30 Dec). Mid to late on day two should see the arrival of the 28 Dec CME bringing active to major storming with it. Day three (31 Dec) should see minor storm levels early in the day before waning CME effects return the Earths magnetic field to unsettled to active levels.
