Rho Cas was observed from 2011-2014 with a digital camera (DSLR). The measures are transformed to Johnson V. The precision of the measures is 0.02-0.03 mag if the star is observed higher than 30 degrees. Together with the (mostly) photoelectric measures in the AAVSO International Database from 1994-2014 the star shows mostly irregular variations between 4.2 and 4.8 mag. The deep minimum of Oct. 2000 (JD2451830) of 5.35 mag is shown. The period of 320 days is not visible in the phase diagram 1994-2014.
