NICER observation list: Target ID 252303

Abstract

With the excellent timing ability, high collecting area in soft X-ray band, and relatively low background below 1 keV, NICER is an ideal telescope for supersoft X-ray sources. We therefore propose 3x50 ksec NICER observations for three supersoft X-ray systems. These observations can be useful in searching for the spin period of the white dwarfs, studying the atmospheric emission, and understanding the supersoft X-ray orbital modulation.
