From Saturday to Sunday the time changes and Portugal officially enters winter time. But a few hours before, still during the so-called summer time, there is a lunar eclipse to see: it is the last of the year. This is a partial lunar eclipse that will be visible in Portugal starting at 7 p.m. this Saturday, October 28.
NASA explains that a partial lunar eclipse occurs when there is “an imperfect alignment of the Sun, Earth and Moon,” causing the “Moon to pass through only part of the Earth’s shadow.”
“The shadow grows and then recedes without completely covering the Moon,” explains the North American space agency.
The total duration of the phenomenon will be four hours and 25 minutes, but the threshold phase, that is, the moment in which the eclipse will be most visible, will have a planned duration of one hour and 17 minutes.
The BBC states that the partial lunar eclipse will begin at 8:35 p.m. and the peak of the phenomenon will occur at 9:14 p.m., in which “around 12% of the Moon’s diameter will be covered by the threshold shadow, which translates into about 6% of the Moon’s disk.” Moon will be eclipsed.”
The partial eclipse will end at 9:53 p.m., when the Moon begins to move away from the Earth’s shadow.
The next partial lunar eclipse won’t occur until next year, on September 18.
