Abstract:
CCD photometric observations in 2016 February and March and a reevaluation of observations made in 2013 June of 19204 Joshuatree show it to be a possible binary. It is another candidate for the special case of very wide binaries. The primary lightcurve has a period of 480 ± 5 h and an amplitude 0.25 ± 0.02 mag. and the secondary lightcurve has a period of 21.25 ± 0.05 h.
