The Zwicky Transient Facility reported observations of a 20th magnitude possible
NEO made on 9 March 2021 with the 1.2m Oschin Schmidt. This was placed on the
PCCP as ZTF0Kij and subsequently found to show cometary features by
astrometrists. It could reach 11th magnitude around the time of perihelion when it will
be at high southern declination.
