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 171 Issued at 2200Z on 19 JUN 1996

IA. Analysis of Solar Active Regions and Activity from 18-2100Z to 19-2100Z

SOLAR ACTIVITY REMAINED VERY LOW. NEW REGION 7973 (N09E71) ROTATED INTO VIEW AS A SMALL H CLASS SUNSPOT GROUP. THIS REGION PRODUCED A LONG DURATION A9 EVENT FROM 19/1104- 1414Z. YOHKOH OBSERVED THE EVENT. ANOTHER SMALLER LONG DURATION EVENT BEGAN NEAR 19/1700Z AND WAS ENDING NEAR 19/2100Z. THE LOCATION FOR THIS EVENT IS UNKNOWN, BUT REGION 7973 IS THE LIKELY SOURCE.
IB. Solar Activity Forecast
SOLAR ACTIVITY SHOULD CONTINUE AT A VERY LOW LEVEL FOR THE NEXT THREE DAYS. THERE IS A SLIGHT POSSIBILITY OF A C-CLASS FLARE FROM REGION 7973.
IIA. Geophysical Activity Summary 18-2100Z to 19-2100Z
THE GEOMAGNETIC FIELD WAS UNSETTLED AT THE BEGINNING OF THE PERIOD. ACTIVE TO MINOR STORM CONDITIONS WERE OBSERVED BETWEEN 19/0000-0600Z. THE SOURCE OF THIS DISTURBANCE IS UNKNOWN. QUIET CONDITIONS WERE OBSERVED FOR THE REMAINDER OF THE PERIOD. REAL-TIME SOLAR WIND DATA WERE RECEIVED DURING THE QUIET PERIODS. STREAM PARAMETERS WERE UNREMARKABLE.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS FORECAST TO BE QUIET TO UNSETTLED FOR THE NEXT THREE DAYS. ISOLATED SUBSTORMS ARE POSSIBLE EARLY ON 20 JUN.
