You are completely right. 

My calculation was based on the orbital elements with 81 obs from July
14 to 28.

However, I found that the ephemeris based on the new elements with 154
obs from July 14 to 30 shows so large difference as some 8 degrees
from that.

So I will calculate the rendezvous just before the approach date and
report again.

Thank you so much for your comments, Dr. Skiff.

Best regards,
