I continued my coverage of KMS-4 and its UNHA-3 r/b (2016-009A & B) on March 3 
and March 5.

As expected, the flash period of the rb (2016-009B) is (very) gradually 
changing, at a rate of about 0.01 second a day. I measured 2.43 seconds on March 
3 and 2.45 seconds on March 5.

More on this here, including a fine 10-second exposure with four flashes:

On popular request, I have also included a brief description on how I process 
and analyse the images to get to these results at the end of that post.
