There is some correction to ATEL #9164, the OT is seen on the sum (540s) of 3 images(180s), started at 2016-06-16 04:47:12UT with m_lim=19.9 (and on the difference from this sum and the image of last year), but this OT is not seen(automatically can't be detected) on the single image at 2016-06-16 04:47:12UT with m_lim=19.3. This is Andromeda field, and the limits are +-0.2, also for the magnitudes of the star near this limit (preliminary automatic values).
