Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 182 Issued at 2200Z on 01 Jul 2014

IA. Analysis of Solar Active Regions and Activity from 30/2100Z to
01/2100Z: Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M1 event observed at
01/1123Z from Region 2106 (N15E46). There are currently 9 numbered
sunspot regions on the disk.

IB. Solar Activity Forecast: Solar activity is expected to be low with
a chance for M-class flares on days one, two, and three (02 Jul, 03 Jul,
04 Jul).

IIA. Geophysical Activity Summary 30/2100Z to 01/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 439 km/s at
01/0500Z. Total IMF reached 6 nT at 30/2130Z. The maximum southward
component of Bz reached -4 nT at 01/0146Z.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (02 Jul, 03 Jul)
and quiet levels on day three (04 Jul).
