Abstract:

The FOXSI-4 sounding rocket experiment aimed to observe medium-to-large solar flares using direct-focusing X-rays and successfully observed an M-class flare during its flight on April 17, 2024. For a flare-triggered rocket launch with only six minutes of observation time, there were large uncertainties in the photon fluxes that FOXSI-4 might encounter. Therefore, FOXSI-4 incorporated insertable attenuators for hard X-ray detectors and enabled different exposure times for soft X-ray detectors to accommodate a wide range of flare classes. Here we present the scientific predictions for FOXSI-4 for various flare classes as a demonstration of the capability of the instrument. In addition, we compare those predictions with the initial results from the flare observed during the actual flight.
