LkHα 225 (V1318 Cyg) South in Outburst

Magakian et al. (2019) called attention to the current bright state of LkHa 225 South, which over past two decades has changed from $>20^m$ $<13^m$. We present recent optical photometric monitoring that shows colorless, non-sinusoidal, periodic brightness variations. The oscillations occur every 43 days, and have amplitude $\sim$0.7 mag with some variation among cycles. also new flux-calibrated near-infrared spectroscopy, we model in terms a keplerian disk. Additional high dispersion spectra demonstrate similarity absorption line pattern categories "mixed temperature" accretion outburst objects. At blue wavelengths, South pure spectrum is good spectral match FU Ori stars V1515 Cyg V1057 Cyg. red infrared however, more similar Gaia 19ajj, showing emission TiO, CO, metals. Sr II lines indicate low surface gravity atmosphere. There are signatures strong wind/outflow. was moderately early 1950's as well late 1980's, evidence for deep fades during intervening epochs. body suggests LkHa225 another case source episodically enhanced causes brightening by orders magnitude, development hot warm wind. It but reminiscent its long time oscillation near peak, embedded sources L1634 IRS7 ESO Ha 99.
