The active region complex 8645/8647 showed collimated ejections while crossing the West limb.

The ejection started from the South end of the complex and its direction was vertical to the limb. The second ejection occurred around 06:10 from the North end of the complex and directed to NW. The ejection speed was about 100 km/s in both events. These ejections were not associated with detectable flares.

FOV of the box is 491" x 737".

Time evolution of the maximum Tb in log scale.
The solid line shows Max (R+L) and the dotted line shows Max (R-L).
Data points are plotted every 10 min.
