Things were pretty quiet in Space Weather today, with the exception of Solar Wind Speed dropping, but still above 400 km/sec and Electron Saturation gathering around its Alert Threshold. We only had B Class Solar Flares today because there are no noteworthy Sun Spots facing Earth, and our HP Index was calm. These conditions will persist for a few days, before the next round of CH HSS arrives around 9/22.
