An earlier telegram (ATel #3458) reported that the narrow-line Seyfert 1 galaxy Zw 229-15 (19h05m25.9s +42d27m40s) exhibited a dramatic decrease in X-ray flux during Swift monitoring, with the count rate dropping from a mean of 0.096 c/s during the ~18 days from May 29 through June 17 to a mean of 0.026 c/s during the ~17 days from June 18 through July 5. (All dates/times UT.) The maximum count rate was 0.172 c/s at 2011 June 2 22:35 and the minimum was 0.005 c/s at June 27 00:23.
