Transient blob in Lya at 1.43 Ro. Also appeared in C III and possibly OVI 1032. |
Transient blob only seen in Lya at 3.12 Ro. Faint with small blue shift. |

| Comments |
Event seen by LASCO shows continuous outflows throughout the UVCS observing period. The HI Lya intensity along the UVCS slit shows some changes in morphology but the event is too faint to single out transient signal.
