  8. 22 October – 521 BRIXIA Occult data shows a dMag of 0.16. Given the low amplitude of 0.11 ± 0.02 mag, it is not possible to say definitively if the solution should be monomodal or bimodal. Assuming the former, a period of 9.78 ± 0.02 h is found. If the bimodal solution is adopted, the period is 19.57 ± 0.02 h. MPB 36-4, p. 172.
