In this paper, we have discussed the unsteady hydromagnetic natural convective rotating flow of an electrically conducting, viscous, incompressible and optically thick radiating second grade fluid past an impulsively moving vertical plate entrenched in a fluid inundated porous medium, while temperature of the plate has a temporarily ramped profile. The solutions of the governing equations are obtained by making use of Laplace transform technique. The expressions for skin friction due to primary and secondary flows and Nusselt number are derived for both ramped temperature and isothermal plates. Sherwood number is also obtained. The velocity, temperature and concentration are exhibited graphically whereas the skin friction components, Nusselt number and Sherwood number are in tabular form with reference to governing parameters.
