=> The clouds, illuminated by the moon, prevented us from starting our observations in the evening. Then the clouds cleared, and we observed for the rest of the night. Most of the observed blocks had high priority.
Science data taken for:
2025-2-MLT-007 P1 RSS (Spectroscopic monitoring of a unique red (?) supergiant in the LMC)
2025-2-SCI-031 P2 RSS (x3) (Redshifts of candidate TeV blazars)
2025-2-SCI-035 P2 RSS (Study of a sample of high redshift radio sources at z>3)
