This old 1997 satellite is doing strange things!
Stayed near 16°W only from Nov 2015 to mid-Feb 2016, since then slowly moving East, with just 0.3° per day (today near 10°E).
I started thinking something must be wrong, out of fuel maybe? But no, ABS-3 is going somewhere, all the way to 85.3°E. At this speed, arrival in October!
