I just noticed that Chi Cyg seems to have hit max and started back down around July 10. This max was only about mag 6.8 (visual), much fainter than recent years, and in fact as faint as I could ever recall. I looked back at the historic maxima and there is one other maximum that faint, in 1937. The next runner-up was a 6.4 in 1930. The mean of the AAVSO minima from 1900-2008 was 5.16, so 6.8 is pretty faint. I don't know what it means, but it's pretty interesting.
