| Summary: | The 1408 CE “guest star” recorded in Chinese historical texts presents a compelling case for identifying a historical stellar transient. While previous studies debated its nature as a meteor, comet, or nova, we reevaluate the event using original Ming Dynasty records, including a newly found memorial from the imperial court. The object, described as stationary for over 10 days, yellow, and luminous (resembling a “Zhou Bo virtue star”), is inconsistent with cometary behavior. Positional analysis locates it near the Niandao asterism (modern Cygnus–Vulpecula region) within the Milky Way, with a derived brightness of −4 to 0 mag. Lightcurve stability over 10 days and color descriptions align with a slow nova or a supernova. We cross-correlated the historical coordinates with modern catalogs and found a few possible counterparts. Among them, CK Vul—a luminous red nova remnant from 1670 to 1672—is the most interesting candidate. Could its progenitor system have experienced a precursor classical nova eruption circa 1408 prior to the merger ∼200 yr later? We also examine cataclysmic variables and planetary nebulae within the 100 square-degree search field, though most lack sufficient brightness or age characteristics. This study emphasizes the value of integrating detailed historical records with contemporary astrophysical data to resolve long-standing controversies over ancient transients. The 1408 event likely represents a rare, well-documented nova, offering insights into premodern stellar phenomena and their modern counterparts. |
