Starting project 13A-537. The band(s) used is(are): L. On source 3C138 with all available antennas. Your data were taken with the new EVLA computer system controlling the Array. Observers should carefully review their observations. Data of a small fraction of projects, in particular those involving novel use of the Widar correlator, will undergo inspection at the NRAO; if that is the case you will receive a separate notification to that effect. For the latest information about accessing your data from the archive, visit: https://science.nrao.edu/facilities/vla/data-archive/. For further questions please use the NRAO helpdesk at: https://science.nrao.edu/observing/helpdesk. Note: To support our ongoing RFI monitoring efforts, any feedback from your program on RFI can be sent to: [email protected].

The key information to provide is: - Observation/project code - Frequency and Time of the observations - The characteristics of the RFI signal, in particular if it is continuous or intermittent? - If possible, a spectrum of the RFI should be included in the e-mail. Thanks very much for your support; this information will be continuously updated on the EVLA science pages at: https://science.nrao.edu/facilities/vla/docs/manuals/obsguide/modes/rfi/ Antenna(s) 19 (Data: Lost): FOCUS/ROTATION Antenna is stowed and locked out due to a problem with the subreflector bearing.
