RZ LMi: possible orbital period Using TESS data in 2020, I detected a period of 0.058005(8) d (amp. 0.02 mag). This value is close to what was derived in Kato et al. (2016) PASJ 68, 107. This result seems to strengthen the idea that the core of the secondary in RZ LMi is evolved, as suggested in Kato et al. (2016). This period was not very apparent in TESS data in 2022.
