After fading from view since early June (magnitude > 21), VSX J205126.1+440523 has significantly brightened and appears to be beginning its very rapid fluctuations again.  It is a very cool object - last night's Imag=15.45, Rmag=17.60.  Earlier this year it varied by almost 4 magnitudes every 2 months. It's Imag has gone from 18.5 to 17.6 in the past week.  This an an interesting object to observe!
