A three-chord occultation plot of the asteroid 77 Frigga, observed 2018 April 11th from eastern Australia.
Since 1999 there have been four stellaroccultations by the asteroid. The first three were single chord observations, and the fourth was a 3-chord observation, and a miss. The best fit ellipse measures 60.0 × 74.0 kilometres at PA -14degrees.[2]
