Stargazing and skywatching from Cosmic Herald — what to see in the night sky, meteor showers, planets, auroras, and observing guides.
The September equinox and an incoming coronal-hole solar wind stream are stacking the odds toward a minor G1 geomagnetic storm and aurora sightings on Sept. 23–24, 2026.
Read the story →Neptune reaches opposition on Sept. 26 at magnitude +7.8 and needs optics, while naked-eye Saturn peaks on Oct. 4, with the Harvest Moon forming a wide triangle with both planets.
NASA's global Moon-watching night lands Sept. 19, 2026 under a waxing gibbous Moon perfect for crater-spotting, anchored by a Huntsville flagship event tied to the Artemis II crew and echoed by local telescope nights from the US to Spain.
Two CMEs and a filament eruption from an active sunspot region are due to strike Earth's magnetic field September 16-17, and NOAA's storm watch means the aurora could sneak into mid-latitude skies this weekend.
Two coronal holes, one in each solar hemisphere, are rotating into Earth-facing position, and forecasters say the resulting solar wind streams could spark G1-level auroras around the equinox.
A new-moon dark sky, the faint September Lyncids meteor shower, and NASA's guide to Venus, the Teapot asterism, and a Harvest Moon beside Saturn and Neptune highlight the second half of September 2026's stargazing calendar.
A city-bus-sized asteroid was spotted over Arizona just six hours before it burned up over the Indian Ocean—becoming only the 13th impactor ever caught in advance, and the first on an orbit inside Earth's own.
The Moon paired with Jupiter before dawn on Sept. 8, and NASA's September guide lines up the Sagittarius Teapot, peak Venus brightness on Sept. 18, and a Saturn-Neptune Harvest Moon on Sept. 26.
NOAA issued a G1-G2 geomagnetic storm watch after sunspot AR4524 fired off four CMEs in two days, and skywatchers from Chicago to Edinburgh — and possibly New York and London — could catch aurora through September 9.
NOAA's Space Weather Prediction Center issued a G1-Minor geomagnetic storm watch for September 8-9 as multiple CMEs and a coronal-hole stream converge on Earth, with aurora possible across the northern U.S. and forecast confidence still low.
Four mornings, Sept. 6-9: a thinning crescent Moon slides past Mars in Gemini, then Jupiter in Cancer, while a C9-flare CME due Sept. 8 puts a "maybe" on high-latitude aurora ahead of the Sept. 11 new Moon.
NOAA logged repeated S1-minor proton storm alerts on September 5 as a coronal mass ejection from sunspot AR4524 heads for Earth, with arrival expected September 8 and a shot at G1-level auroras.
