Stealth CME passage?
The strength of the interplanetary magnetic field (Bt) is elevated right now at about 17nT which is a moderately high value. We suspect that a slow coronal mass ejection which slipped under everyone's radar is passing our planet right now as the way the interplanetary magnetic field behaves is consistent with the signature of a CME core passing our planet.
