Description
The Radio Neutrino Observatory - Greenland (RNO-G) is a multipurpose experiment that extends its scope to sciences like solar heliophysics and radioglaciology beyond its primary focus to detect ultra-high energy neutrinos and cosmic rays. In this contribution, we discuss the recent observations of solar flares in RNO-G. The nanosecond-sampling of the recorded snapshots allows to study the radio emission with finer resolution in the time-domain compared to dedicated solar observatories. Additionally, we highlight RNO-G's ability to utilize the known positions of the Sun to calibrate the detector and achieve sub-degree reconstruction precision. The summer 2022 and 2023 datasets used in this search came from 7 out of the planned 35 radio-receiver stations, each equipped with 24 antennas sensitive to impulsive radio signals in the 80-700 MHz bandwidth. Further confirmations on signal excesses during solar flares were obtained through coincidence measurements in the Callisto network and the SWAVES satellite. As RNO-G expands, it will continue to refine its capabilities, offering high-resolution solar flare data and precise cosmic ray and neutrino reconstructions. With the solar maximum in 2024 data, RNO-G has the potential to provide valuable insights into both astrophysical and solar phenomena, positioning it as a versatile and impactful detector for multi-disciplinary science.
