You mean oumuamua? After it rounded the sun it accelerated as it left the solar system. No propulsion, out gassing, etc could be detected. Another strange anomaly.
3I/ATLAS is the third interstellar object confirmed passing through the Solar System, after 1I/ʻOumuamua (discovered in October 2017) and 2I/Borisov (discovered in August 2019).
And we all know that the Ramans do everything in threes!!!
