Young protostars that undergo episodic accretion can provide insight into theimpact on their circumstellar environments while matter is accreted from thedisk onto the protostar. IRAS 22343+7501 is a four component protostar systemwith one of those being a fading outbursting protostar referred to as L1251 VLA6. Given the rarity of YSOs undergoing this type of accretion, L1251 VLA 6 canelucidate the fading phase of the post-outburst process. Here we examinestructure in the disk around L1251 VLA 6 at frequencies of 10 GHz and 33 GHzwith the Karl G. Jansky Very Large Array (VLA). We model the disk structureusing Markov chain Monte Carlo (MCMC). This method is then combined with aparametric ray-tracing code to generate synthetic model images of anaxisymmetric disk, allowing us to characterize the radial distribution of dustin the system. The results of our MCMC fit show that the most probable valuesfor the mass and radius are consistent with values typical of Class I objects.We find that the total mass of the disk is $0.070^{+0.031}_{-0.2} \rm ~M_{\sun}$ and investigate the conditions that could cause the accretionoutburst. We conclude that the eruption is not caused by gravitationalinstability and consider alternative explanations and trigger mechanisms.
