Query: SN 2011ht: Weak explosion in massive extended envelope   A possibility is explored to account for the light curve and the low
expansion velocity of the supernova SN~2011ht, a member of group of three
objects showing signatures of both IIn and IIP supernovae. It is argued that
the radiated energy and the expansion velocity are consistent with the low
energy explosion ($\approx6\times10^{49}$ erg) and $\leq 2 M_{\odot}$ ejecta
interacting with the circumstellar envelope of $6-8 M_{\odot}$ and the radius
of $~2\times10^{14}$ cm. The test of this scenario is proposed.
