An occultation by Laurentia was observed from Clive, Alberta on 21 November 1999.August 2020 Photometric observations of this asteroid from multiple observatories during 2007 gave a light curve with a period of 11.8686 ± 0.0004 hours and a brightness variation of 0.40 ± 0.05 in magnitude. This is in agreement with previous studies in 1994 and 2007. References Donald K.
