A new hole has opened in the sun's atmosphere, and it is spewing a stream of solar wind toward Earth. Estimated time of arrival: Oct. 30-31. The expected solar wind enhancement could trigger another round of minor (G1) storming at higher latitudes. Weak enhancements are likely to continue into Nov. 1st as the Coronal Hole High Speed Stream (CH HSS) effects linger. Spectacular Displays of Aurora are Expected. Arctic sky watchers may get a treat for Halloween: Aurora Boo-realis.
