Our Sun calms down this week as region 2745 rotates off the west limb and on to the backside. We are dealing with a slight enhancement due to some mildly fast solar wind that could bump us to active conditions over the next few days, but only at high latitudes. On a more exciting front, a returning set of coronal holes rotates into view, which could bump us to storm levels with some decent fast solar wind in about 10 days. This should give aurora photographers something to anticipate. Unfortunately, the bright regions that were sandwiched between these coronal holes have decayed severely. They will not boost the solar flux much, if at all, for amateur radio operators and emergency responders. This means radio propagation will remain poor on Earth's dayside for at least another week or (likely) more. At least the quiet Space Weather means GPS users can expect great reception on Earth's dayside and at low latitudes over the next week.

None of this would be possible without the hard work and dedication of those who have provided all of this data for public use.

Images c/o NASA/ESA/CSA (most notably the superb SDO, SOHO, ACE, STEREO, CCMC, JPL & DSN teams, amazing professionals, hobbyists, institutions, organizations, agencies and amateurs such as those at the USAF/HAARP, NICT, NOAA, USGS, Environment Canada, Natural Resources Canada, Intellicast, Catatania, rice.edu, wisc.edu, sonoma.edu ucalgary.ca, rssi.ru, ohio-state.edu, solen.info, and more. Thanks for making Space Weather part of our every day dialogue.
