Goldstone discovered 2 moonlets . the inner satelite is revolving at about 8 hours and is eclipsing the asteroid. with current telescope system, Ds/Dp<0.1 making detection of mutual events unachievable (private correspondence P.Pravec)

Observed with JBL01

3122 Florence

the data for 03/09 show a steady decline in brightness indicating the rapid recession of the asteroid as it moves away from earth.

so far the data show a short period of 3.77h however large amplitude was noted with 120h long period when 09/08 and 09/10 data was reduced where zero point difference was shown as 0.8mag. short period  of 3.77his shown within each session
