WESTPORT — Not since the July 4 holiday fireworks have celestial phenomena attracted so much skyward attention this week from Westporters.

First, a NASA rocket ferrying supplies to the International Space Station was visible Tuesday evening as it streaked above Westport en route to its destination.

A little later, a “super moon” rose spectacularly over the horizon, appearing bigger and brighter than full moons usually do because it occurred during the moon’s closest approach to Earth. The brilliant lunar light has been nearly as stellar in its waxing and waning phases.

That full moon, nicknamed the “Sturgeon” moon, unusually will not be the only full moon this month.

On Aug. 30, a second full moon — also a super moon — will be visible in local skies. Because of its rarity, that moon also will be known as a “blue moon,” in astronomical terms.

In the meantime, however, the clear skies that made such cosmic viewing possible are forecast to cloud over Friday, bringing  a chance of rain and thunderstorms by nighttime, according to the National Weather Service.
