Target Info
Target Name: ZTF21AANXHJV
Target No.: 5205
Category: ACTIVE GALAXIES AND QUASARS

Constraint Details
Monitor: Y
Criteria: Around the X-ray peak of the TDE AT2019azh, it exhibits mini-outbursts every 20 day (see Fig. 14 of Hinkle+2021), and the variability is correlated with changes in the blackbody temperature. In order to test if similar behavior exists in ZTF21aanxhjv, we request a cadence of 1--2 days to probe the rapid X-ray spectral evolution.
