With the 0.43-m telescope of Burro, Australia.

These are probably my last observations of this object, as it is getting beyond
mag + 19 now. I could only see it during the brightness peaks in its brightness
variation cycle, even though 2-minute exposures were used this time.

During the Feb 15 observations, it was as far away as 0.018057 AU, or 2.7
Million km (7 Lunar distances).

Same data in MPC format:
