Night Sky 19 August 2025 - 28 September 2025

An impressive partial solar eclipse will greet early-risers on Sunday, Sept 21, 2025. This eclipse is “deep” – at peak about 85% of the sun’s disk will be covered by the moon earthsky.org. The eclipse path spans the South Pacific, including much of New Zealand, a thin slice of eastern Australia’s coast, parts of Antarctica, and various Pacific islands space.com. In these regions the event happens around local sunrise on the 22nd earthsky.org. Observers there will see the sun rise already partially eclipsed – a spectacular sight if weather permits. Maximum obscuration occurs at 19:41 UTC on Sept 21 earthsky.org. By the time the moon’s shadow departs Earth at 21:53 UTC, the sun will gradually return to full brightness earthsky.org.

One of this week’s big celestial events was an unexpected aurora display that ventured far beyond the polar regions. A long-lasting solar flare on Aug 30 unleashed a coronal mass ejection toward Earth, sparking a geomagnetic storm that hit on Sept 1–2 ts2.tech ts2.tech. The result: vibrant Northern Lights danced in the sky on those nights, delighting skywatchers much farther south than usual. Observers reported auroral glows in at least 18 U.S. states – sightings came from states like Oregon, Illinois, and New York – and even across the Atlantic in the U.K. Midlands ts2.tech. This was due to the storm reaching G2–G3 strength as the CME buffeted Earth’s magnetic field ts2.tech ts2.tech.

Total Lunar Eclipse & “Corn Moon”: On the night of September 7, Earth’s shadow will completely engulf the full Moon, causing a total lunar eclipse that lasts about 82 minutes timesofindia.indiatimes.com. During totality, the Moon will dim to a deep reddish hue – hence the dramatic “Blood Moon” nickname nationalgeographic.com earthsky.org. This eerie copper-red color occurs because Earth’s atmosphere scatters blue light and bends some red sunlight into the shadow, painting the Moon in sunset shades science.nasa.gov. “Total lunar eclipses can turn a deep shade of red and are often called a Blood Moon,” explains EarthSky, an astronomy news outlet earthsky.org. The September full Moon is traditionally called the Corn Moon, marking the harvest season in many Native American cultures starwalk.space. For skywatchers across Asia, Australia, Europe, and Africa, this eclipse will be visible in entirety or in part accuweather.com. In fact, Europe, Africa, and Asia get the best view, with the Moon rising already eclipsed in some places and turning red high in the sky in others nationalgeographic.com. Observers in the Americas will miss the eclipse, but they can still enjoy the brilliant full Corn Moon that evening nationalgeographic.com. No special equipment is needed to enjoy a lunar eclipse

On August 23, the night sky will host an unusual lunar event known as a “Black Moon.” You won’t actually see the Moon at all during this rare occurrence space.com – in fact, that’s the whole point. A Black Moon is essentially an extra new moon in the calendar, a once-in-33-month phenomenon livescience.com that turns the night sky especially dark. In this in-depth guide, we’ll explain what a Black Moon is, why it’s so rare, the astronomy behind it rising with the sun, and how skywatchers can make the most of this August 23 Black Moon. We’ll also touch on cultural and astrological perspectives surrounding this eerie-sounding event.

Get ready for a rare celestial light show: A minor geomagnetic storm is forecast to make the aurora borealis visible much farther south than usual on the night of August 19, 2025. Skywatchers from Alaska and the Pacific Northwest to the Upper Midwest and New England – potentially even parts of Iowa and northern Illinois – have a chance to glimpse the aurora low on the horizon or dancing overhead in green and purple hues ts2.tech ts2.tech. This event is notable because auroras rarely reach such southerly U.S. latitudes except during stronger solar storms. Below, we break down the science behind the aurora, why tonight’s display is special, where it will be visible, the current space weather conditions, and how to maximize your chances of seeing this natural spectacle.
