An account in Haut-Rhin, France

On December 29, 2013, at around 5:45 a.m., a witness on the terrace of their home is intrigued by the presence in the sky of a glow that appears between clouds, then a shimmering disc. The static object quickly disappears behind the clouds. No other testimony has been reported. The witness describes a "slightly tilted disc, shimmering, light yellow in color" observed for 2 seconds through a gap in the clouds; they indicate a direction of observation "above Cernay, seen from Steinbach toward Mulhouse, therefore south": the map shows that the direction of Cernay and Mulhouse is to the southeast (approximate azimuth: 125°). The sky chart indicates at 129° azimuth and 9° elevation the presence of the Moon, in its last quarter (a very tilted thin crescent). It is highly likely that the witness did not recognize the Moon due to the clouds and the brevity of the observation. GEIPAN classifies this case "B" as a probable observation of the Moon. Due to the difference in elevation estimate between the witness's report (20°) and that of the Moon (9°), a slight doubt remains about the hypothesis presented.
