It's 7:48 AM and that is about the latest I have experienced until all clouds cover Mayon volcano during my 10 days photo sessions around Mt Mayon volcano and its neighborhood of Albay province.
On fullmoon nights Mt Mayon easily can be recognized naked all night long - just like Filipina girls - Mayon only is naked in night time - as soon as daylight shows, the active volcano hides within an hour or two behind dense clouds all day long.
Best time for Photography of Mt Mayon volcano is after 5 AM until approximately 7 AM. After 7 AM Mayon is visible only on rare occasions.
