     Starting program: AH695,  observe file:  347H695.

00Mar31 14:05:00
     On source 2321-1631 with all available antennas. 
     The band(s) used is(are) L   band(s).

00Mar31 14:04:09
     The on-line baseline parameters for antenna(s) 2 11 15 18 26 27  
     have recently been updated (prior to your observing run) to correct
     for errors resulting from their recent relocations.  In the analysis of
     your data would you please check for any significant baseline
     errors especially on these antennas and let the Data Analysts (email
     - analysts@nrao.edu) know what you find when there are
     significant baseline errors.  Thank you in advance.

   Form #: C101482           # of Ants: 1.00               Downtime: 388.52
     Antenna(s) 19 - FOC ROT (Focus Rotation Mount and Controls)
     Problem(s); Antenna currently stowed because subreflector is stuck

00Mar31 14:34:16
     Shadowing is occurring! Some antennas are blocking the view of your 
     radio source from other antennas. You may have to edit your data.
     Observing Data: Corrupted.
