The asteroid light curve was measured to be 5.216h
Followed the next month with a longer light curve of 5.276h, a margin of error that is not acceptable.
Attempt to confirm the correct light curve failed due to poor weather condition in the following month, dimming and change viewing geometry to polar aspect causing a considerable reduction in the lightcurve amplitude.
Shortening of the observing session also did not help.
The PSABA asteroid has very low amplitude
Its light curve period is not well defined . The period recorded here is U=2
Period estimated at 3.57h
Pravec et al. (2018) found it at 5.42h at U=2
Asteroid is found to have a unique period of 4.1979h
