Captured a lone point on USA 186 yesterday evening, just before a pass of the 
UNHA-3 r/b 2016-009B.

In order to try to capture a larger arc for KMS-4 and the UNHA-3 r/b I used the 
1.4/85 mm lens, with 2 second exposures for KMS-4 and 5 second exposures for the 
UNHA-3 r/b.

2016-009B showed nice flashes again. From three images spanning 25 seconds, I 
obtained another very nice brightness profile. Like that of the previous 
evening, it fits a period of 2.39 seconds.

Profile can be seen here :

The trails of Kwangmyŏngsŏng-4 (KMS-4: 2016-009A) barely showed on the images 
(smaller lens aperture, lower elevation and a decidedly less good sky compared 
to the previous night). Yet it is (very, very faintly) present on 4 images.

Over that 17-second time span again has no discernable brightness variation.

Tacsat 4 was captured as a stray on the KMS-4 images.
