3 Day Geomagnetic Forecast

:Product: 3-Day Forecast :Issued: 2017 Jan 30 0030 UTC # Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center # A. NOAA Geomagnetic Activity Observation and Forecast
The greatest observed 3 hr Kp over the past 24 hours was 3 (below NOAA Scale levels). The greatest expected 3 hr Kp for Jan 30-Feb 01 2017 is 5 (NOAA Scale G1).
NOAA Kp index breakdown Jan 30-Feb 01 2017
Jan 30 Jan 31 Feb 01 00-03UT 3 3 5 (G1) 03-06UT 3 5 (G1) 4 06-09UT 2 5 (G1) 3 09-12UT 2 4 3 12-15UT 2 3 3 15-18UT 2 4 3 18-21UT 2 4 3 21-00UT 2 4 4
Rationale: G1 (Minor) geomagnetic storms are likely on days two and three (Jan 31 and Feb 01) due to the anticipated arrival of a co-rotating interaction region in advance of a recurrent, negative polarity coronal hole high-speed stream.
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.

**** SPACE WEATHER OUTLOOK ****
Summary For January 23-29
No space weather storms were observed.
Outlook For January 30-February 5
G1 (Minor) geomagnetic storm levels are likely on 31 January and 01 February due to recurrent coronal hole high speed stream effects.
