Re: ASASSN-21nv: at least four rebrightenings

The (super?)outburst started on 2021 July 27. A rapid fading began on August 23. Short rebrightenings were recorded on August 27 and 30, and on September 2 and 4. (according to ZTF, ATLAS and ASAS-SN data)

Look like a short rebrightening and a long one (according to ZTF Lasair). ASAS-SN data are noisy (fainter thans around positive detections).
