SN2024iss
We propose a ToO observation of supernovae (SN) in nearby galaxies. Goal is to detect emission lines including Fe-K lines and measure their center energy and width (minimum case). In addition, when the flux is higher, we could measure metal abundance pattern and ionization state of CSM. From these measurements, we can obtain information on physical properties of circumstellar (CSM) medium around SN. If the SN is enough bright to monitor a long time trend, we propose one more observation after one month or later to probe a mass loss history of progenitor (ideal case).
