The 11 September 1983 occultation of 14 Psc by (51) Nemausa was observed photoelectrically at six sites across the occultation track. The observations are well represented by an elliptical limb profile having a semimajor axis of 84.9±2.0 km and oblateness (1-barcmin/aarcmin) 0.20±0.05. The geocentric position of the asteroid was 0s.18843±0s.00022 E and 3arcsec.5696±0arcsec.0030 N of 14 Psc at 7:45:00 UTC on 11 September 1983. The quoted uncertainties are all formal errors from the elliptical least-squares fit. No secondary occultations were observed.
