SDSSJ090113.51+144704.6 orbital period Confirmation of https://arxiv.org/abs/2301.08581 Porb = 0.146326(4) d from the TESS data. What were reported to be grazing eclipses had a mean depth of 0.015 mag and I cannot tell whether they are eclipses or not. The claimed IW And-type phenomenon was not followed by fading from the standstill (ATLAS and ASAS-SN). My conclusion is UGZ (as original) or UGZ+E:
