I have seen this object three more times since the first
observation.  One yielded a standard magnitude of around 4.

On 7 April 2017 at 259 UT, I watched a short pass through
the telescope that gave a standard magnitude of about 2.4.
On that pass the range was 17526 km and a phase angle of
126.7 with an observed magnitude of about 7.8

I also noticed a possible variation of about 0.5 magnitude
with a max/min/max period of roughly 30 seconds.

Last night I again observed it at 310 UT (10 April 2017)
at a range of 29115 km.  Rob Matson Skymap phase angle was
98.9.  Magnitude was 8.5 and this time clearly did fluctuate
to invisible with a rough max/min/max period of 40 seconds.
Standard magnitude last night was 1.4

8" Celestron telescope used for all observations from Falcon, CO USA.
