How does that match up with [0]?

"... a satellite that stalks other satellites, started another relocation move on July 22, leaving its position near ASTRA 4A at longitude 4.8 E and drifting west at 0.9 degrees per day."

Do they make this up, or do you and I have a vastly different understanding of "irregular"?

That is interesting. I wonder how many stalking maneuvers it can do before it depletes it's propellant/reaction mass.

It's not made up. The satellite made some minor orbital parameter changes but at all times it was in a regular orbit. It wasn't making irregular course changes in the way that an airplane might.
