Accompanied by increases in speed, density and temperature. Possible causes include associated CMEs. Halo CME associated with M2.1 flare from AR13296 (N15E30). From LASSOS team discussion: Arrival on 5/7 is indicated by a sheath crossing and high field strength. No flux rope is observed in this signature.
