November 2019’s Monthly Media was of nearly 2 days of observing with the Engineering Development Array 2 (EDA2) at the Murchison Radio Observatory (MRO), from Associate Professor Randall Wayth.

The Milky Way, the Sun, the nearby galaxy Centaurus A and other space objects as they pass overhead.

This above GIF shows snapshots of the radio sky above the Murchison Radio Observatory taken at 64 second intervals at a frequency of 230 MHz, covering roughly 1.75 days of continuous data. The colour bar at the bottom shows radio intensity (brightness) in the commonly-used astronomer units of Jy/beam (Jansky per beam). The celestial coordinate system (CCS) is also overlaid on the image to aid the eye (the gridded circle), and the apparent low-level radio emission outside the CCS is an artefact of the imaging process and is not real.

The EDA2 tests the proposed antenna layout of the SKA-LOW using the current technology of the Murchison Widefield Array (MWA) dipoles.
