The ISW imprint of superstructures of size \\sim100\\;h^{-1} Mpc at redshift $z\\sim0.5$ has been detected with $>4\\sigma$ significance, however it has been noted that the signal is much larger than expected. We revisit the calculation using linear theory predictions in \\Lambda CDM cosmology for the number density of superstructures and their radial density profile, and take possible selection effects into account.
