The International Space Station raised its orbit a couple of weeks back to avoid a close approach by an Argentinian imaging satellite.

A Progress MS-22 spacecraft docked to the station fired its thrusters for over six minutes.

This changed the station's velocity by 0.7 meters per second.

This means each orbit takes a bit longer.

Amateurs using the ARISS repeaters will want to be sure to have updated Keplerian elements for prediction and tracking software.
