The sun is becoming active again

He wrote, giving some important advice for sun photography: “With mostly cloudy skies predicted within the hour I put my itsy bitsy 66mm refractor to work on the sun to photograph enormous sun spot AR 2781 as it traverses the solar disk. Sunspot AR2781 poses a threat for C-class solar flares. AR 2781 is so big people have reported seeing at sunset through thin clouds and haze with unfiltered optics! But please note, even when the sun is dimmed by low-hanging clouds or haze, it can still be dangerously bright, especially when magnified by unfiltered optics. If you choose to photograph the low sun, use the camera’s LCD screen for safe view finding. Never look at the sun through the eyepiece of an unfiltered camera. NEVER!” Thank you, Victor!

The sun’s new 11-year cycle of activity (Cycle 25) has just started, after being at a low ebb in recent years. Expect sunspots to become more common in the years ahead. Read more about Cycle 25.

Bottom line: Photos from the EarthSky community of an active region on the sun – a giant sunspot region – known as AR 2781. It was making its way across the sun’s visible surface last week, but will soon rotate out of view, moving to the back side of the sun.
