V1219 Cyg - a YSO showing deep fades

Within a search for outbursts among variable stars of Orion type by comparing DSS and DSSII images, V1219 Cyg was identified as potential candidate. While modeling its SED, the 2MASS magnitudes turned out to be too faint by about 3 mag. The NIR fluxes derived from the UKIDSS images are consistent with SED models, and confirm that the object was much dimmer during the 2MASS observations. Thus, instead of hinting at an outburst, the initial find points to a previous fading during the DSS epoch. We characterize this interesting YSO using new observations performed with the Tautenburg 2-m telescope as well as a wealth of archival data.
