Region 3664 continues to produce large X-ray flares as it continues its transit of the western limb. The latest two came within 12 hours of each other. We could continue to see flares from this region for the next day or so, but any CMEs associated with these flares are not likely to have any impacts at Earth. If it holds together, we could see Region 3664 rotate back onto the visible side of the Sun in about two weeks!  Stay tuned to our website for updated forecasts, watches, warnings, and alerts.
