The object has been variable and the amplitude of the magnitude was about 2 mag. The V-J color was also variable. When the object was bright, the V-J color was bluer. This feature is called the "bluer-when-brighter".
The figure shows the light curve and the temporal variation of the polarization degree in V band. The object has been faded since JD 2454750. In JD 2454985, the object was the faintest state. On the other hand, the polarization degree has been risen. During JD 2454960, the polarization degree reached 38 %.
