On November 14, 2003, Titan occulted two bright Tycho stars (V= 8.4 and V= 10.3). The first event was observed in the Indian Ocean and southern Africa, while the second one was followed from western Europe, northern and central Americas. Data were gathered by both professional and amateur astronomers, using fixed and portable telescopes at wavelengths ranging from visible to near IR (K band).
