Gradual optical brightening in GRO J0422+32 during quiescence: precursor to an outburst? [V518 Per]
ATel #16831 https://www.astronomerstelegram.org/?read=16831
presents data on the recent brightening of this low mass X-ray object, which is a black hole candidate, aka V518 Per. They suggest it might be associated with increased activity in the accretion disc and speculate it might be heading towards outburst.
It last went into outburst in 1992.
Mag. range 13.15 – 22.6 V
Go well!
