It passed by KSI Aquila (RA 19:55, Dec +08:30) about
12:50:32 UT, 1 March 2015.   Magnitude estimated at 5.5
using the 4.7 magnitude KSI Aquila as a reference.

At a range of 1070 km, Skymap phase angle of 46.5 degrees
that is a standard magnitude of about 3.4.

Averaging with my previous standard magnitude of 2 and
dropping a bit to be conservative, I put it at 3.0 with
my normal caveats of higher magnitude estimates error
than others might have.

I had tried to see it with binoculars in Cygnus a minute
earlier but twilight made finding the target stars uncertain.
Missing it that way was inconclusive.
