  Several technosignature techniques focus on historic events such as SN 1987A
as the basis to search for coordinated signal broadcasts from extraterrestrial
agents. The recently discovered SN 2023ixf in the spiral galaxy M101 is the
nearest Type II supernova in over a decade, and will serve as an important
benchmark event. Here we review the potential for SN 2023ixf to advance ongoing
techonsignature searches, particularly signal-synchronization techniques such
as the "SETI Ellipsoid". We find that more than 100 stars within 100 pc are
already close to intersecting this SETI Ellipsoid, providing numerous targets
for real-time monitoring within ~3$^\circ$ of SN 2023ixf. We are commencing a
radio technosignature monitoring campaign of these targets with the Allen
Telescope Array and the Green Bank Telescope.
