Yes, we have NO impact plume. That's this past week's report from the Hubble Space Telescope, which followed up the amateur-observed June 3rd event. Probably "a giant meteor burning up high above Jupiter's cloud tops ... best guess [is that these] smallest detectable events may happen as frequently as every few weeks."

NEOCP Activity on 19 June '10
The MPC's NEO Confirmation Page has 22 listings: 13 new, 9 updated
When last checked at 2359 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had thirteen new and nine updated listings. Of these, eleven were "one nighters." So far The Tracking News has counted a total of 30 listings on the NEOCP at some point today.
To learn how observers use the NEOCP, see the Practical guide on how to observe NEOCP object at Suno Observatory by Birtwhistle et al.

An impact solution, also known as a "virtual impactor" (VI), is not a prediction but rather a possibility derived from a variant orbit calculation that cannot be eliminated yet based on the existing data. Elimination can come quickly with just a little further observation or may take weeks or months, sometimes years. Once superceded or eliminated, a former impact solution has zero relevance to an object's risk. See Jon Giorgini's "Understanding Risk Pages" to learn more.
