The CME never arrived

Well that was a bust forecast! An excellent forecast for several nights turned into a no-show for the coronal mass ejection (CME). The North Pole webcam did capture a pretty big, but short show on Sept 1 unrelated to the CME, but was due to a nice sustained negative Bz. You can watch the cam’s video here. Tonight and tomorrow night, back to background levels, with a chance for unsettled conditions (Kp 3) by Sept 5.
