Although designed for detection of cosmic ray neutrinos, the RNO-G detector serendipitously registered signals on Sept. 29, 2022 (approximately 48 hours before illumination of the solar panels fell below threshold to power the array) which were ultimately traced to a solar flare event on that day. Closer examination of the 2022 and 2023 RNO-G data revealed almost 100 solar flare events, each of which produced anywhere from tens to hundreds of triggers in the RNO-G
stations. We detail, in this contribution, how those events were identified and subsequently used to calibrate the positions of the in-ice antennas on centimeter scales.
