Dual Origins of Rapid Flare Ribbon Downflows in an X9-class Solar Flare
Ryan J. French, William H. Ashfield, Cole A. Tamburri +4
We detect rapid downflows of 150-217 km/s in IRIS Si IV 1402.77 nm measurements of an X9-class solar flare on 2024 October 3rd. The fast redshift values persist for over 15 minutes…
