The large group of sunspots known to scientists as AR2403 has now rotated out of view, around the sun’s limb, but it was spectacular when it was visible. As the sun spun on its axis, it appeared to move across the sun’s visible face over six days, from August 21 to 26, 2015, starting out as a single cluster, and gradually separating into distinct groups.

Venus has returned to the east before dawn. Mars is up there, too, but not nearly as bright. See Venus, and capture Mars now with binoculars or in photos.
No photo in our social media last week had had as much positive feedback as this one, which Jeff Berkes posted at EarthSky Facebook. He wrote:
I still can not believe that I had the opportunity to witness a view as heavenly as this.
It’s a beauty! Also known as Messier 33, it’s about three million light-years away – the second closest large galaxy to our own Milky Way.

Because Peter Lowenstein lives in the Southern Hemisphere, he was fortunate enough to see the young waxing crescent moon and the planet Mercury in the western sky after sunset on August 16, 2015. In fact, the Southern Hemisphere will be enjoying Mercury’s best evening apparition of the year in August and September 2015. At temperate latitudes in the Southern Hemisphere, Mercury will set after nightfall for the next four weeks!
Have you seen Perseid meteors in your sky? If you have had cloudy skies – or even if not – enjoy these images from all around the world.
Inside, we show you six of Peter’s wonderful photos of the western sky after sunset on August 3, 4, 5, 6, 7 and 8, 2015. Notice how fast Mercury is soaring upward by the day, and how quickly Venus and Jupiter are sinking! Click here to see Peter’s youtube animation of the planets from August 3 to 8!
