Proper motion and photographic photometry of R Leonis Minoris (the maser source IRC+30215).
Abstract
The position, absolute proper motion (Table 3), photograhic photometry (Table 1) of the long period variable R LMi (the maser source IRC+30215) obtained using normal astrograph plates are given in the paper. The epochs differ by 24.92 years. The r.m.s. errors of the co-ordinates are sigma(RA) = 0.008 s, sigma (Dec) = 0.10", those for proper motions are sigma (mu-RA cos dec) = 0.0073", sigma (mu-dec) = 0.0050". Two stars in the region of R LMi have been suspected in variability (Table 1).
