Blobrana · L

On December 11.4, 2010, the Catalina Sky Survey detected asteroid Scheila mimicking a main-belt comet and displaying a "coma" of about magnitude 13.5. Scheila's coma may be the result of cometary outgassing or an asteroid impact as happened with P/2010 A2 . Archived Catalina images suggest that this outburst may have started around December 3, 2010.
