SOLAR WIND STORM, SUBSIDING: The solar wind blowing around Earth is beginning to slow, dipping below 600 km/s. This is still a fast wind, but given the low density and weak magnetization of the gaseous material, it is not enough to spark geomagnetic storms. The chances for auroras tonight are decreasing. Aurora alerts: SMS Text
MIDSUMMER AURORAS: As a rule, northern summer is a bad time to see auroras. August 5th was the exception to the rule. A solar wind stream hit Earth's magnetic field, sparking a G1-class geomagnetic storm. Auroras blossomed over Canada, then spilled across the 49th parallel to the United States. Rocky Raybell photographed the display from Keller, Washington:
"The show started around 2 am Pacific Time then lasted until daylight, with red columns turning purple just before dawn," says Raybell. Elsewhere in the USA, the lights were seen from Kalispell, Montana and the Olympic National Park.
The solar wind stream came from a large hole in the sun's atmosphere--so large that Earth is still inside. NOAA forecasters say there is a 65% chance of additional G1-class geomagnetic storms on August 6th.

G1).
The greatest expected 3 hr Kp for Aug 06-Aug 08 2019 is 5 (NOAA Scale
G1).

B. NOAA Solar Radiation Activity Observation and Forecast
Solar radiation, as observed by NOAA GOES-14 over the past 24 hours, was
below S-scale storm level thresholds.

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.
