Monitoring SgrA* and its Interaction with the G2 Gas Cloud

Since the announcement of the planned response of the G2 encounter with SgrA* in the Galactic center, NRAO has been undertaking bi-monthly VLA monitoring observations in advance of the expected encounter in mid-2013.

The Jansky Very Large Array (VLA) monitoring data are being obtained under project code TOBS0006, and the raw data are available through the NRAO Archive. Photometry, calibrated visibility data, and some images are posted at the NRAO Service Observing page.
