| Giant sunspots, solar flares, aurora alert! | | | Sunwatchers are still tracking those 2 huge sunspot groups making their way across the Earth-facing side of the sun. Then yesterday there was a giant X-flare! Watch for possible auroras. | | | | See an extra-red moon or sun this week? | | | If you live in the U.S. or Canada, a peculiarly red moon - or very spectacular sunrise or sunset - might be due to smoke from wildfires. Click in for images from Earth and space. | | | | Asteroid spacecraft to slingshot past Earth | | A NASA mission to return a sample from an asteroid will soon get a planned gravity assist from Earth. You can spot the spacecraft in the sky and submit images … or participate in NASA's Wave to OSIRIS-REX campaign. | | | | | | | |

|  | | Giant sunspots, solar flares, aurora alert! | | Gowrishankar Lakshminarayanan called this: "… a surreal sunset from Fire Island Lighthouse in Fire Island, New York. You can see the 2 giant sunspots – AR2673 and AR2674 – as the sun is setting." The sunspots are visible to the eye, but you must use a safe solar filter. Your eclipse glasses will work! | | | | | |

 | | | Watch for zodiacal light, aka false dawn | | Talay Daniel Erol caught this image of bright Venus the east before dawn – in the midst of the pyramid-shaped, ghostly zodiacal light – from Adrasan Antalya, Turkey. | | |
