Something must have happened with this, looks stellar in DR10
Honestly, I have no idea what caused this. This is an R Coronae Borealis variable and it seems to have been measured by Gaia DR2 as a magnitude of 12.65 (G) and in Gaia EDR3 seems to be measured with a magnitude of 16.77 (G). Maybe EDR3 might have measured 16th magnitude due to its variability, and the LS might have over-subtracted this star. DR10 seems to have fixed this issue with DR3 I assume
LS DR8 - Gaia DR2 - magnitude 12.65
LS DR9 - Gaia EDR3 - magnitude 16.77
LS DR10 - Gaia DR3 - Magnitude 12.65
It seems the Gaia mission has detected this in EDR3 until it was fixed in DR3.
These state it all from SIMBAD.
