SUNSPOT SUNSETS: Solar Cycle 25 is changing the way sunsets look. It is adding some spots. "Active sunspot complex AR2993-94 was visible yesterday at sunset," says Marek Nikodem, who sends this picture from Szubin, Poland:
"Distance to the city visible on the horizon: 24 kilometers," says Nikodem. "Distance to sunspots: 150 million kilometers. Such is the scale of the Solar System! Unfortunately, the sky turned out to be partially cloudy, which made it impossible to photograph the full sun disc. Still, it was a stunning sight."
A note of caution: Photographing the sun is dangerous. Even a brief glimpse of magnified sunlight can damage your eyes. In Nikodem's case, the sun was dimmed enough for photography by haze and low clouds. Even so, he pointed his camera safely using an electronic viewscreen; looking through an old-fashioned optical viewfinder is *not* recommended.
