The relaxing phase of the subflare observed in the core of chromospheric
Ca II K line and in two photospheric Fe I 522.5 nm and Fe I 557.6 nm lines
was investigated. The temporal evolution of asymmetry in Ca II K line and the
mean bisectors positions of the Fe I line profiles as well as their
correlations are presented.
It is documented that the chromospheric down-flow caused by the subflare
strongly affects the upper layers of the photosphere.
As a consequence of relaxation of the photospheric layers strong down-flows
and up-fows were measured at the end of the subflare relaxing phase.
