The Astro2020 Decadal Survey recommended an investment in Time Domain and Multi-Messenger Astrophysics (TDAMM) as the top-priority sustaining activity in space for the coming decade. This relatively new field burst onto the scene with the detection of neutrinos and photons from SN 1987A, and entered a new era in 2017, with the first detection of a binary neutron star merger, GW 170817 / GRB 170817A, in both gravitational waves and across the electromagnetic spectrum, and the second strong association between an astrophysical neutrino, IceCube-170922A, and a known source, the blazar TXS 0506+056. The field’s potential continues to grow as searches for electromagnetic counterparts to GW events continue and with the high-significance detection of neutrino emission from the galaxy NGC 1068. The TDAMM Science Interest Group (SIG) was recently chartered as a venue for the community to provide analysis and feedback to NASA regarding TDAMM science, as well as establish and disseminate best practices for conducting TDAMM science, for missions both in development and in operations, and for observers and investigators, including in regards to sharing and citing data in an era of open data. Here we report on recent activities of this group.
