Observation notes:

The observation session felt unusually focused, with repeated returns to the same fields and repeated instrument checks despite stable conditions.

Several members remarked that familiar regions of the sky appeared difficult to describe in ordinary observational terms.

At least two observers independently reported that a star appeared to dim and brighten once, almost like a blink, too quickly for ordinary variable-star behaviour.

The group returned several times to the same region because the first impression could not be dismissed, yet no conventional explanation was agreed upon.

Members present: Adama Traoré, Ayoub Berrabeh, Claire Dumont, Antoine Delorme
