Fortaleza approach region — five white lights oscillating in altitude

On 17 September 2025 at 03:30 Z, one observer on a flight from SBTE to Fortaleza, SBFZ, reported five intense white lights. The ten-minute observation was recorded near the FLZ navigation reference, with the coordinate 04°14′04″S, 040°07′30″W. The lights were described as medium-sized and oscillating in altitude around flight level 180; their shapes, spacing and distance from the observer were not specified. No observing equipment or physical recording was reported. Sound and trail answers are negative, although the adjacent intensity field contains the inconsistent word “strong.” Other effects and weather are not described. CINDACTA III logged the report at 03:30 Z. The two-page form supplies no additional event sequence, identification or investigative conclusion. Source review: Two pages visually reviewed. The flight-level value is an observer report, not an independently measured object altitude. NIL is treated as unavailable information.
