Radio Observatory Report Antonis Polatidis ASTRON is part of the Netherlands Organisation for Scientific Research (NWO)

Development Work / Issues 8 new stations ready to integrate in the array (in final stage of validation) - 6 Core stations, 2 Remote. LOFAR MoM being tested. SAS/MAC related : Work ongoing to kickstart and observe with Tautenburg Test the integration of the 8 new stations (today) Setting up stations for pulsar observations OK - CEP has to be started separately. combining arbitrary groups of stations for recording stability of SAS/MAC system being tested now. Problem with CS002: Blown fuse

Observations Imaging BW5: Testing wide-field imaging with LBA in a field with bright point sources (Obs 251) Test observation of pulsar B1508+55 to check whether day-to-day variations were due to snow. Under Consideration: Imaging BW5: 10-75 MHz observations of the 3C196 field (Obs 243) Cas A observation with as many HBA stations as possible

25 Jan - 29 Jan: Imaging BW5 in Leiden “Busy Week” plans Busy Weeks 25 Jan - 29 Jan: Imaging BW5 in Leiden 15 Feb - 19 Feb: “Control & Metadata” BW1 15 Mar - 19 Mar: “Control & Metadata” BW2 To test the flow of an observation and its metadata from beginning (NorthStar/MoM) to the end (Archive).
