Please send the tapes via normal tape channels so they get in the tabe library safely. ank@apo.nmsu.edu wrote: > Tuesday Jun 26 2001 > > Apache Point Observatory SDSS 2.5m > > Observing Log > > (MJD 52087) > > OBSERVING TEAM: > =============== > Dan Long (APO) > Atsuko Nitta Kleinman (APO) > Bryan Laubscher (LANL) --PT > > Scot Kleinman (APO) > > VISITORS: > ========= > > THE PLAN: > ========= > Science > > SYNOPSIS FOR NIGHT: > =================== > No science data.
