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.
Solar and Geophysical Activity Summary 2015 Dec 30 0245 UTCPrepared by the NOAA © SWPC and processed by SpaceWeatherLive.com
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 DecA. Energetic Events
Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep None
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.
