LSPM J0651+1843 and LSPM J0651+1845 are two high-proper-motion stars recentlyclaimed to form a binary system, FMR 83, by Rica (2012). Here we characterizethe system in detail, using astrometric and photometric data, and find that thepair consists of two M4+/-1 dwarfs separated by 9500^(+6200)_(-3800) AU. Withthese results, FMR 83 becomes one of the very few 'ultrafragile' systems (i.e.,systems with very low total masses and very wide physical separations), many ofwhich have been identified in this series of papers.

Cool dwarfs in wide multiple systems. Paper 4: a common-proper-motion pair of two identical mid-M dwarfs separated by about 10000 AU
