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.

IA. Analysis of Solar Active Regions and Activity from 27-2100Z to 28-2100Z

Solar activity has been very low. Region 1084 (S19E46) was quiet and stable. No flares were observed during the period.
IB. Solar Activity Forecast
Solar activity is expected to be very low.
IIA. Geophysical Activity Summary 27-2100Z to 28-2100Z
The geomagnetic field has been predominately quiet with an isolated unsettled period at 27/0300-0600Z. Observations from the ACE satellite indicate the continuation of a high speed solar wind stream, with wind speeds at about 525km/s during the period.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet to unsettled on days one and two (29-30 June). Quiet to unsettled conditions with isolated active periods are expected on day three (01-July).
