[vsnet-newvar 9196] PKS 2258-022 = MGAB-V1095: short-period variation

PKS 2258-022 = MGAB-V1095: short-period variation This object is identified with a radio-loud QSO (z=0.778). However, the ZTF data show short-term variations. The data were well expressed by a period of 0.1417938(2) d. The profile resembles that of a polar. There is no indication of z=0 feature in the SDSS spectrum. Very strange object!
