The main belt asteroid (1026) Ingrid was defined by Cikota et al. 2014 (A&A, 562, 94) as a candidate object that possibly show a type of comet-like activity. We observed
this object using a 0.35-m f/11 telescope at Mt. Teide, Spain, between May and June 2014. The weighted average colors of Ingrid suggest a S-like taxonomic
classification (Table. 1) in Tholen system (see Dandy et al. 2003, Icarus, 163, 363), typical of Flora family asteroids (Florczak et al. 1998, Icarus, 133, 233). This object presented a V
magnitude variation, relative to the Minor Planet Center (MPC) ephemerids magnitude,which are in agreement with an amplitude greater than 0.5 mag of its
light curve (Skekely al. 2005, Planet. Space Sci., 53, 925) and stellar profile (Fig.1). Based
in the previous results, we did not detect cometary activity in (1026) Ingrid.
