Recent brightening. 2MASS 191837.288 +212722.31 (2000.0) 13.810 12.942 12.628 191837.292 +212722.14 (2000.0) Gaia_DR2_4517076551873840384 plx=1.660(0.085) dismod=8.9 pmra=0.697(0.116) pmdec=-6.845(0.153) G=17.188 BP=18.800 RP=15.916 191837.292 +212722.13 (2000.0) Gaia_EDR3_4517076551873840384 plx=1.533(0.063) dismod=9.1 pmra=0.700(0.058) pmdec=-6.627(0.065) G=17.150 BP=18.664 RP=15.905 The object is too underluminous for a Mira/SR (thus not likely a symbiotic nova). FU Ori star? Somewhat close to a star-forming region.
