Solar activity 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 Report of Solar and Geophysical Activity
SDF Number 194 Issued at 2200Z on 12 JUL 1996IA. Analysis of Solar Active Regions and Activity from 11-2100Z to 12-2100Z SOLAR ACTIVITY CONTINUED AT A LOW LEVEL. REGION
7978 (S12W75) PRODUCED A MODERATE DURATION C4/1F FLARE AT
12/1532Z. A FILAMENT FADED DURING OR SLIGHTLY BEFORE THIS EVENT
AND SIGNIFICANT MASS MOTIONS WERE OBSERVED. REGION 7978
CONTINUED TO SLOWLY DECAY AND IS NOW CLASSIFIED MAGNETICALLY
AS A SIMPLE BETA.
IB. Solar Activity Forecast
SOLAR ACTIVITY SHOULD CONTINUE
LOW FOR THE NEXT TWO DAYS BEFORE REGION 7978 ROTATES OVER THE
WEST LIMB. C-CLASS FLARES SHOULD BE INFREQUENT.
IIA. Geophysical Activity Summary 11-2100Z to 12-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED FOR THE PERIOD.
RECENT SOLAR WIND DATA INDICATE THE CORONAL MASS EJECTION
HAS NOT IMPACTED THE EARTH.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
FORECAST TO BE QUIET TO UNSETTLED FOR 13-14 JUL WITH A SLIGHT
POSSIBILITY OF ACTIVE CONDITIONS LATE ON 13 JUL AND EARLY ON
14 JUL. QUIET CONDITIONS ARE EXPECTED TO BEGIN ON 15 JUL.
