I'm sad to report the death of Ed Stone, the NASA scientist who was the heart & soul of the Voyager program. Spending time with him for my Discover magazine profile was a highlight of my career.

AR3664 was in fact recharging and did in fact have a grand return! 💥 X2 flare observed while the region is still mostly around the southeast limb accompanied by a dense CME (not Earth-directed). Buckle up, it might be another long and active two weeks!
