Solar wind speed increased from lows near 330 km\/s midday to approximately 470 km\/s by the end of the period. Total magnetic field strength ranged from 3-17 nT. The Bz component was southward through most of the day and reached as far south as -14 nT around 18:00 UTC. Phi angle was mostly negative after 03:00 UTC on March 23.<\/p>\n<p>Solar wind parameters are expected to contain enhancements from a negative polarity coronal hole high speed stream (CH HSS) early on March 24. <\/p>\n<p>From late March 24 into March 25, we expect the effects of a CME produced by the X1.1 flare on March 23 to begin impacting us.
