We present observations and analysis of PSN J17292918+7542390, alow-luminosity Type II-P supernova (LL SN IIP). The observed sample of suchevents is still low, and their nature is still under debate. Such supernovaeare similar to SN 2005cs, a well-observed low-luminosity Type II-P event,having low expansion velocities, and small ejected $^{56}$Ni mass. We havedeveloped a robust and relatively fast Monte-Carlo code that fits semi-analyticmodels to light curves of core collapse supernovae. This allows the estimationof the most important physical parameters, like the radius of the progenitorstar, the mass of the ejected envelope, the mass of the radioactive nickelsynthesized during the explosion, among others. PSN J17292918+7542390 has $R_0= 91_{-70}^{+119} \cdot 10^{11} \;\text{cm}$, $M_\text{ej} =9.89_{-1.00}^{+2.10} \; M_{\odot}$, $E_{\mathrm{kin}} = 0.65_{-0.18}^{+0.19}\;\text{foe}$, $v_{\mathrm{exp}} = 3332_{-347}^{+216}$ km s$^{-1}$, for itsprogenitor radius, ejecta mass, kinetic energy and expansion velocity,respectively. The initial nickel mass of the PSN J17292918+7542390 turned outto be $1.55_{-0.70}^{+0.75} \cdot 10^{-3} M_{\odot}$. The measured photosphericvelocity at the earliest observed phase is 7000 km s$^{-1}$. As far as we cantell based on the small population of observed low-luminosity Type II-Psupernovae, the determined values are typical for these events.
