 More recent polarimetric observations also characterized the asteroid as a dark F-type.Several rotational lightcurves of "Flammario" have been obtained from photometric observations since the 1990s ().Analysis of the best-rated lightcurve obtained by French amateur astronomer Laurent Bernasconi in January 2005 gave a rotation period of 12.160 hours with a consolidated brightness amplitude between 0.14 and 0.40 magnitude ().
