Event 23 (raster 21, 9-Feb-2011, 07:23)

Narrow column jet at bottom of EIS raster. Associated with the large BP, but there's no obvious BP at base of jet. The jet runs along the edge of a region of bright 195 emission. Velocities are about 20 km/s. The AIA movie does not reveal anything significant, so I flag this as a dark jet, although I add 'complex' to denote the complex environment in which it occurs.

For this long jet, intensities vary from 90 at the base to 25 at the tip, and widths from 80 to 90 mA. There are weak asymmetries in the line profile, and velocities range from 10 to 20 km/s.

AIA 193 movie (log intensity, 1 min cadence, 41mins, 0.9 MB)
AIA 193 difference movie (1 min cadence, 41mins, 2.5 MB)

These movies have been constructed by summing five images over each 1 minute period.
