Near-Earth Asteroid 2026 KT2 was observed for two hours starting on 2026 May 28 at 21:03 UT from Olmen Observatory by Alfons Diepvens. 
    Unfiltered 5-s exposures were obtained using a 0.20-m f/6.75 refractor and an SBIG ST-10XME CCD camera. 
    Photometry was measured via Astrometrica using comparison stars from the Gaia DR2 catalog.  
    
    A period analysis conducted by Eric Broens using the Phase Dispersion Minimization (PDM) method revealed a super-fast rotation period of 142.9 ± 0.4 s, 
    consistent with the class of super-fast rotators, typically defined as P < 10 min.  
    
    The uncertainty was estimated from the full width at half minimum of the PDM theta statistic in frequency space, 
    propagated to period space. 
    A visual inspection of the phase diagram with the error margin applied confirms this to be a conservative error estimate.
