A. NOAA Geomagnetic Activity Observation and Forecast

The greatest observed 3 hr Kp over the past 24 hours was 2 (below NOAA
Scale levels).
The greatest expected 3 hr Kp for Jun 30-Jul 02 2015 is 3 (below NOAA
Scale levels).

21-00UT        2          2          2

Rationale: No G1 (Minor) or greater geomagnetic storms are expected. The
geomagnetic field is expected to be mostly quiet on days one through
three (30 Jun - 02 Jul), with isolated periods of unsettled activity
possible on day two (01 Jul) in response to a small positive polarity
coronal hole.

B. NOAA Solar Radiation Activity Observation and Forecast

Solar radiation, as observed by NOAA GOES-13 over the past 24 hours, was
below S-scale storm level thresholds.

Solar Radiation Storm Forecast for Jun 30-Jul 02 2015

S1 or greater    1%      1%      1%

Rationale: No S1 (Minor) or greater solar radiation storms are expected.
No significant active region activity favorable for radiation storm
production is forecast.

C. NOAA Radio Blackout Activity and Forecast

No radio blackouts were observed over the past 24 hours.

Radio Blackout Forecast for Jun 30-Jul 02 2015

              Jun 30        Jul 01        Jul 02

R3 or greater    1%            1%            1%

Rationale: There is a slight chance for M-class (R1-R2, Minor-Moderate)
flare activity on days one through three (30 Jun - 02 Jul) primarily due
to Regions 2373 and 2376.
