Sun, spotted: Our speckled star shines over New York City (photo)

 Alexander Krivenyshev, president of WorldTimeZone.com, captured these shots of the sun over New York City from New Jersey on Nov. 28, 2020, using a Canon EOS7D camera. The closeup of the sun, taken with the aid of a solar filter, shows the sunspots AR2786 and AR2785.

A speckled sun shines down on New York City in a gorgeous skywatcher photo.

Amateur astronomer Alexander Krivenyshev, president of WorldTimeZone.com, photographed the sun over the Big Apple on Saturday morning (Nov. 28). A close-up image he captured clearly shows a big sunspot known as AR2786 and its smaller cousin, AR2785.

Krivenyshev took the photos using a Canon EOS7D camera, with a solar filter attached for the close-up. Caution: Do not attempt to get such shots unless you too have a solar filter. Looking directly at the sun, with the naked eye or through instruments such as cameras or telescopes, can cause serious and permanent eye damage, including blindness.

AR2786 and AR2785 rotated into view shortly before Thanksgiving. AR2786 is several times wider than Earth.

Sunspots are temporary dark patches that are significantly cooler than the rest of the solar surface — about 6,500 degrees Fahrenheit (3,600 degrees Celsius), compared to 10,000 degrees F (5,500 C). 

Sunspots occur where solar magnetic fields are especially strong, and they serve as launch pads for flares and eruptions of superhot plasma known as coronal mass ejections. For centuries, scientists have counted sunspots as a way to gauge solar activity.

That activity waxes and wanes on an 11-year cycle. The latest one, solar cycle 25, began in December 2019 and is expected to be fairly quiet, as solar cycle 24 was. But the sun is now acting out, at least a little bit: On Sunday (Nov. 29), our star fired off its most powerful flare in more than three years.
