$\begin{figure} \par\includegraphics[width=16.9cm,height=15.1cm,clip]{mainfig.eps}\end{figure}$ Figure 1: Spectral energy distributions of 6 FU Orionis-type objects. Open symbols correspond to the epoch of $\sim$ 1983 while filled symbols mark the SED as of 1996-2000. The data are presented with no reddening correction. Error bars smaller than the symbol size were not plotted. For V1331 Cyg there are no NIR data from 1983; we plotted data from 1979 (the K-band lightcurve shows constant flux in this period). In the case of V346 Nor the ISO and IRAS beams also include the nearby pre-main sequence star Reipurth 13. For comparison the plotted MSX flux densities are sums of the individual fluxes of the two objects.

$\begin{figure} \par\includegraphics[width=8.2cm,height=7.1cm,clip]{SED2.eps}\end{figure}$ Figure 2: Spectral energy distribution of V1057 Cyg. Open and filled symbols are as in Fig. 1. No reddening correction was performed. The lower panel shows the ratios of fluxes obtained at the two epochs ( $\sim$ 1983 to 1996-2000).

$\begin{figure} \par\includegraphics[width=8cm,height=12.3cm,clip]{klight.eps}\end{figure}$ Figure 3: K-band lightcurve of 6 FU Orionis objects for the period 1963-2003. Data are taken from the literature (for Parsamian 21 no observations are available). Grey stripes mark the two epochs (1983 and 1996-2000) which form the baseline for the long-term evolution.
