MGAB-V701 to MGAB-V750 light curves

MGAB-V701

Gaia EDR3 position: 204.065725 38.159300

Variability type: UG

Variability range: 18.2 - 21.8 g

MGAB-V702

Gaia EDR3 position: 239.998818 39.954147

Variability type: UG

Variability range: 19.0 - 21.9 g

Remarks: The target shows superoutburst every 160-170 days. Multiple outbursts between are seen, with variable duration and amplitude. Standstill-like features are seen, suggesting an Z Cam type behaviour, however high short-term variations make it unclear without time-series data from ZTF. Possible VY Scl-type dimming observed between HJD 2458272-2458284.
