Number of Antennas Used: 27
11Mar 12:24:40 Starting project 22B-193.
11Mar 12:24:40 The band(s) used is(are): X K.
11Mar 12:31:20 On source 1331+305 with all available antennas.
11Mar 12:24:40 Antenna(s):28 do not have good baseline positions determined for them because they were moved to their present location recently. Please check for any significant errors and submit them to the NRAO Helpdesk (https://science.nrao.edu/observing/helpdesk) under the VLA Observing department.

11Mar 12:24:40 Note: To support our ongoing RFI monitoring efforts, any feedback from your program on RFI can be sent to: nrao-rfi@nrao.edu 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/
