"It’s mission is classified, so who knows what it will be up to as it passes overhead? The orbit is changed often, whenever the Air Force detects Chinese or Russian satellites moving into its path for a closer look."
I suspect this is quite likely, but do you have any evidence to back it up? I haven't heard anything about X-37B changing orbit in relation to other satellites, but then again, I haven't looked for reports about it.
PS. I'm sorry for the lack of ISS viewing predictions in recent months. The Iridium flares are just about over, but given the pandemic, working from home and dealing with UKIRT transferring over to the IfA at the University of Hawaii has kept me busy and somewhat drained of enthusiasm to keep those detailed predictions going. I'll get back on the job sometime next year I think. That's if people are still interested.
