Congratulations Leo for finding that :

>91-19 B IS ACCELERATING !!!!
Unfortenately, my observing session was blocked last night by
a farmer who suddenly started to work on a nearby field (with
big lights of course)..., so I didn't saw 91- 19 B.  I did saw
it two nights ago.

It is indeed mentioned as a beginner object in our program.rob.

All observers should focus on this object !

Here are the latest OIG elements :
