Event 4 (raster 6, 8-Feb-2011, 15:58)

This was the first of five EIS events that came from a bright point that was present from the beginning of the HOP 177 sequence and lived for about 26 hours longer.The others are 10, 19, 21 and 27.

In the EIS 195 image, the bright point has a squarish shape about 25"x25", with the brightest region in the bottom right corner. The EIS jet extends southward for about 40" from the middle part of the bright point, just to the right of the brightest region. Although column-like, it is quite diffuse and broad, diverging with height. Note that the bright point does not emit in Fe XV 284.

The AIA movie does not show any evidence of a jet-like structure coming from the BP. The BP is quite dynamic, but there is no obvious event that could be related to the EIS feature.

The EIS line profiles in the jet are about 90-100 mA, and thus broader than surrounding coronal hole. The line profiles also show evidence of asymmetry, with an enhanced blue wing.

AIA 193 movie (log intensity, 1min cadence, 40mins, 1.6MB)
AIA 193 difference movie (1min cadence, 40mins, 1.8MB)

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