Observational history
editThe comet was discovered by Alexander F. I. Forbes as a 9th-magnitude object on the early morning skies of 31 May 1930. It was the fifth new comet of the year and the second of three comets he discovered overall.[4] He immediately informed the Union Observatory in Johannesburg after an exact position was determined about two days later.[1]
