They say that these clouds are extremely rare, and are almost primarily seen at high latitudes, like in our area in Los Baños where colder temperatures aid in their formation. Your place in Bukidnon is also at a high latitude if I am not mistaken. Maybe you simply missed the beauty of the iridescent/rainbow 🌈 clouds. They are also much more visible near sunrise and sunset when these thin, wispy clouds are more visible. From this moment forth, you must be vigilant in your surroundings, especially in the atmosphere, to witness this beautiful work of God.🌷🕊️
