Another more Potent Stream of Solar Wind is Coming
ANOTHER STREAM OF SOLAR WIND IS COMING: As Earth exits one stream of solar wind, another more potent stream is approaching. NOAA forecasters estimate a 50% chance of polar geomagnetic storms on Jan. 31st when the solar wind makes first contact. Feb. 1st could be even stormier as Earth moves deeper into the stream. Arctic sky watchers, prepare for auroras.
A G1 (Minor) Geomagnetic Storm Watch has been issued for 31 January 2017 (UTC day) due the anticipated arrival of a co-rotating interaction region in advance of a recurrent, negative polarity coronal hole high-speed stream.
Solar Wind Speed: 456 km/sec Solar Wind Magnetic Fields: Bt 5 nT, Bz -2 nT http://www.swpc.noaa.gov/

Next Coronal Hole in Line
The next coronal hole in line (CH 58) is expected to become geoeffective by late on January 31st or February 1st. Enhanced geomagnetic activity, including minor (G1) storm levels will be possible once a high speed solar wind stream flowing from this zone reaches Earth.
