It was observed for only one month between September 24 and October 26
in 1960. Then it had been lost.
Because of the large perihelion distance of 4 A.U., it returns almost
in the same condition every time. It is always faint.
LINEAR or NEAT have not surveyed yet at the return in 1995.
It was re-discovered in 2012 by the Mount Lemmon Survey, when it returned in the era of automated survey for the first time.
