ISS Reboost: This morning at 4:06am EST, the ISS successfully performed a reboost using the SM Main Engines. The purpose of this reboost is to test the SM main engines prior to the larger reboost scheduled for 1/24. The combination of these two reboosts will set up phasing for Progress 36P launch and several FD3 (Flight Day 3) rendezvous launch opportunities for STS-130/20A. Burn duration was 54 sec, delta-V 1.02 m/s (3.35 ft/s), with a mean altitude gain of 1.77 km (0.86 nmi). This was the first time in about a year that the SM engines have been used for reboost. The second reboost with a delta-V of 2.8 m/s will have a duration of ~3 min and is scheduled for 1/24 at ~4:00am. [After the reboost this morning, the crew noticed a metallic cylindrical object, floating freely immediately nadir and forward of ISS as viewed from the SM. Photos were downlinked.]

Given the small size of the object, perhaps it is a tool or part from a craft or equipment that was lost during a previous mission?
