SAN DIEGO (FOX 5/KUSI) -- San Diegans were treated to an astronomical spectacle as a supermoon illuminated the sky this week throughout the Northern Hemisphere. The moon officially turned full Thursday morning around 4:26 a.m. On Wednesday around 5:48 p.m., the moon had reached its perigee, or closest point to Earth -- about 221,938 miles away. When a full moon coincides with its perigee, it becomes a "supermoon." The Hunter's Moon captured in downtown San Diego.

This week, the supermoon also happened simultaneously with another event to delight stargazers. The comet Tsuchinshan-ATLAS was visible earlier this week in San Diego County and is continuing its trek through the skies of the Northern Hemisphere.

The best opportunity to spot the comet will be from now until Oct. 26. It is not expected to be seen for another 80,000 years, according to experts. The last supermoon of the year is expected to be on Friday, Nov. 15 around 1:29 p.m., according to NASA.
