It's probably the retired JEM ICS-EF, which was jettisoned from ISS on Friday.  From and

ISS Daily Summary Report - 2/21/2020

Japanese Experiment Module (JEM) Inter-orbit Communication System (ICS)-Exposed Facility (EF) Jettison: At 12:50 CT today, robotics ground controllers commanded an SSRMS disposal jettison of the retired JEM ICS-EF, a sub-component of the JEM ICS communications system. The Kibo Inter-Orbit Communication System (ICS) provided an independent intercommunications network between the Kibo module and Tsukuba Space Center (TKSC) of the Japan Aerospace Exploration Agency (JAXA). The ICS-EF was launched on the STS-127 mission (2J/A) in July of 2009, and was attached to the Exposed Facility Unit (EFU)-7 where it was in service until August of 2017. Kibo science data is now delivered via the ISS Ku-band system which utilizes the expanded coverage of the Tracking and Data Relay Satellite System (TDRSS) network.

Anyone any idea what this object is? There does not appear to be an obvious candidate, other than one of the recently released cubesats, which however are very small.
