a Heliocentric distance of the Hayabusa2 spacecraft and b its ecliptic longitude, c Galactic longitude, and d Galactic latitude of the antisolar direction during the period from April 2021 to March 2023. The regions suitable for ZL observations are shown in red, and unsuitable periods owing to pointing toward the Galactic plane (Galactic latitude \(< 20^{\circ }\)) and the Galactic center (Galactic longitude \(< 20^{\circ }\)) are shown in blue and green, respectively
