| Abstract: |
Two ultraviolet explosive events are reported here; one which lasted over 2 mins and was detected in a region within the northern polar coronal hole and a second event which lasted over 4 mins and was detected within an active region. The coronal hole event first showed a mass upflow, followed by blue and red-shifted plasma, then finally a red-shifted plasma. Velocities reached ~120 km s^{-1}. The active region event was more energetic, showing a second injection after about 2 mins. The maximum velocity reached 300 km s^{-1}. Towards the end of each of these events, the location of the mass upflow/downflow had shifted by 3-4 arcsec compared to the initial location. |
