A cosmic event not seen in 36 years — a rare “super blood blue moon” — may be glimpsed today in various parts of the world including Pakistan. The event is causing a buzz because it combines three unusual lunar events — an extra big super moon, a blue moon, and a total lunar eclipse. A blue moon refers to the second full moon in a month. Typically, a blue moon happens every two years and eight months. This full moon is also the third in a series of “supermoons,” which happen when the moon is closest to Earth in its orbit. This point, called the perigee, makes the moon appear 14 percent larger and 30 percent brighter. According to the meteorological department, partial eclipse in Pakistan will start at 3:51pm. The super blood blue moon will be visible in Karachi at 6:12pm , and in Islamabad at 5:32pm .
