ATTENTION: measured mag 12.45 is 3.1 mag brighter than the VSX record maximum brightness 15.50 - possible unusual activity of a known variable! (Alternatively, this may be a new object that coincides with the known variable's position just by chance.)
The object was not found in astcheck.
Check this position in TNS.                         Manually check the ASAS-SN list of transients!

This value should be representative of the faintest stars clearly visible in the image. The brighter of the limiting magnitude estimates for the two second-epoch images is reported here. The second estimate is the 80th percentile of the magnitude distribution of stars detected on all four images.

This value should be representative of the faintest stars clearly visible in the image. The brighter of the limiting magnitude estimates for the two second-epoch images is reported here. The second estimate is the 80th percentile of the magnitude distribution of stars detected on all four images.
