Notes. Observation type includes time-series photometry (Phot.), colour photometry (Colo.), and visible spectra (Spec.). The UTC time corresponding to the start of the observations, the predicted apparent V magnitude (mV), the phase angle (α), and the geocentric(Δ) and heliocentric (r) distances are shown (obtained using the MPC ephemeris service accessed on 30 March 2023).
