(The Great Solstice Aurora from Alan Dyer on Vimeo).
The Sun flared late last week and sent a series of coronal mass ejections in our direction. The high-speed charged particles smacked into the Earth’s upper atmosphere on June 22, 2015, and ignited aurorae borealis as far south as Georgia and Virginia, for example. The deep-southern hemisphere had fine shows of aurorae australis as well. If you missed these splendid vistas, the striking timelapse by astrophotographer Alan Dyer will give you a taste of the intensity and color of the display. Dyer is a master of nightscape and timelapse photography, and when he learned of the possibility of a striking auroral display, he packed his equipment and set to work. He wrote of his impromptu timelapse project on the night of summer solstice: [Read more…] about Aurorae at Summer Solstice

Venus and Jupiter continue to move together each night on the way to their closest encounter on June 30, 2015. This weekend the two planets are still 6º apart, but stargazers may get their best photo opportunity during this conjunction as the two planets are joined by a slender crescent Moon in the western sky after sunset on June 19-20. Venus and Jupiter form a straight line with the bright white star Regulus in the constellation Leo to the east, while Castor and Pollux in Gemini linger to the west. In a telescope, brilliant Venus now appears as a thick crescent while Jupiter, which appears smaller and fainter, still shows its cloud bands and four bright moons.
