These observations detected two new kinematic components of ionized gas whose velocities differ greatly from the +25 km/s molecular cloud surrounding the Sickle. One component is highly red-shifted with peak velocity of about +150 km/s and the other is a blue-shifted velocity feature peaking near -35 km/s. Neither of these high-velocity features have molecular counterparts.
