Notes.a Phases are relative to the R-band maximum light: MJD=56324.5.
b Unfiltered data reported to broad-band Johnson-Cousins R magnitudes.
1 This limit was obtained by L. Elenin (Lyubertsy, Russia) and I. Molotov (Moscow, Russia) through a 0.45-m f/2.8 telescope plus KAF09000 CCD, which is also reported in the Central Bureau for Astronomical Telegrams (CBAT, see http://www.cbat.eps.harvard.edu/unconf/followups/J15213475-0722183.html).
