The Saint-Mathias account concerns observations near Saint-Mathias-de-Chambly, Quebec, in early October 1973. The imported catalogue assigns October 6 at 12:50 a.m. and compresses the episode into a descending beam, a saucer, five small figures and a rectangular object. Fuller compilations separate the initial nighttime lights from an observation later in the morning.
In that daylight phase, a married couple reportedly noticed what first resembled a domed tent in a field roughly a third of a mile away. Five small figures wore conspicuous yellow clothing and helmets. They moved between the larger object and a smaller, box-like object travelling close to the ground. This is a more specific description than the catalogue’s generic humanoid classification.
Published versions disagree on October 5 versus October 6 and on some clothing and movement details. The catalogue also codes illness, disturbed ground and vegetation, but the accessible summaries do not supply an examination establishing their cause. The reconstruction therefore follows the reported morning scene and uses a month-only date.
The film uses October 6; the imported variants use October 5 and 6. The initial nighttime light and the later morning dome/five figures are distinct phases. The couple looked away before everything disappeared and did not watch a takeoff. Clothing varies between yellow and orange. The daughter’s illness was not scientifically linked to radiation, and differing circle dimensions remain source variants.
