A thermal subflare occurring on 27 October 1993 was observed during a multi-wavelength campaign with the Yohkoh spacecraft and the Multi-channel Subtractive Double-Pass spectrograph (MSDP) at Pic du Midi. The various instruments provided us with 2-D Hα spectra, X-ray spectra and X-ray images. A non-LTE computation (including chromospheric condensation) was carried out to determine the dynamic parameters of the flaring chromosphere. By combining these results with the Yohkoh data, we illustrate that momentum is balanced between the upflowing plasma and the downflowing cool plasma during the flare. This result is consistent with the evaporation model.
