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.

Lucille remarked that familiar stars seemed to possess abnormal depth, as if the field opened behind them rather than beyond them.

Members present: Adama Traoré, Ayoub Berrabeh, Lucille Godefert, Marc Lefèvre, Paul Garnier
