We prepared and submitted the test solar project 2025.1.00005.CSV, a Band 5 observation of the Sun using a small subset of antennas pointing 2 degrees off source. The purpose of the test is to verify the methodology of indirect PWV measurements from science SPWs by comparing close antenna pairs, where one antenna points at the Sun while the other measures the WVR signal at a nearby off-source position. We prepared the OT proposal, continuously updated the ephemerides, and cooperated with P2G on the creation and upgrading of the scheduling blocks. We also led communication with AoD through JIRA tickets.
