Run summary by Ramesh:

Although the night started well (~0.6-0.7" seeing) it ended up very badly. We had repeated internal power failures which cost us almost entire of the second half of the night. I managed to get only ~ 30 min of data at the very end of the night (after twilight). Below is a brief summary of what we obtained last night:

1. RXC0232 :

Total integration: 2 hr.

Few emission lines in 2-3 arcs & several other emission features in cluster galaxies.

2. MACS0257 :

Total Integration: ~ 45 min. (Power failure in the middle of an exposure)

Emission lines in at least 3 arcs.

Emission line in SN host galaxy.

Several emission lines in cluster members.

3. A3192 :

Total integration: 30 min (after twilight).

Faint emission line from an arc
