SPACEWEATHER: Artificial Light in the Darkness

An artist’s concept of sunlight beamed down from orbit. Bats, fireflies, and other creatures of the night could find their darkness interrupted by roving spots of artificial sunlight

THIS SOUNDS LIKE A REALLY BAD IDEA: Since SpaceX began launching Starlink satellites in 2019, astronomers have grown increasingly concerned. It’s almost impossible now to take a deep-sky image without satellite streaks in the background. The megaconstellation numbers nearly 11,000 functioning satellites, and SpaceX launched another 1,730 during the first half of 2026 alone.

Soon, Starlink may be the least of their worries.

SPACEWEATHER: Spinning Sunspot, a Fly-Over, and the New Moon

Rotation of a sunspot – AR4482, Taken by Maximilian-Vlad Teodorescu on July 11, 2026 @ Institute of Space Science, Romania

Turning To the Light

Photo Details:
Sunspots rotate. It is known for some time now, but it is nice to actually see that for yourself. Here is a crude animation showing sunspot group AR4482 over the course of 5 days (7 to 11 of July, 2026). Note the different sections rotate differently. The upper part rotates anticlockwise quite fast, while the lower part has different motions inside it. More on sunspot rotation here.

A SPINNING SUNSPOT: Planets spin. Moons spin. Stars spin. Is it any surprise that sunspots also spin? Maximilian-Vlad Teodorico photographed the phenomenon last week (July 7-11) when sunspot AR4482 pinwheeled across the solar disk:

SPACEWEATHER: Earth Reaches Aphelion, Arriving Sunspot 4482, Nature’s Fireworks

Earth’s Farthest Distance from the Sun

Earth reached Aphelion today, July 6, 2026, at 17:30 UTC (12:30 PM CDT). The Days of Earth’s Perihelion and Aphelion positions are significant astronomical measures, though they are rarely acknowledged in the news.

  • Aphelion is the point of the Earth’s orbit that is farthest away from the Sun. It always happens in early July, about 2 weeks after the June solstice,
  • Perihelion is the point of the Earth’s orbit that is nearest to the Sun. This always happens in early January, about 2 weeks after the December Solstice.

The words come from ancient Greek, in which helios means “Sun,” apo means “far,” and peri means “close.”

At Aphelion, Earth was roughly 94.5 million miles (152.1 million kilometers) away from the Sun, about 3.1 million miles farther than at its closest point (perihelion). Despite being at its farthest point from the Sun, the entire planet actually receives about 7% less intense sunlight, though the distance does not dictate the seasons. Summer in the Northern Hemisphere is caused by the planet’s 23.5-degree axial tilt, which points the northern half of the globe towards the Sun for longer, warmer days.  (Old Farmer’s Almanac)

Home Base: Jackie and Shadow’s Nest

Sandy and Luna, 07/03/2026 – Jackie and Shadow’s nest with a view of the rising Sun and the Big Bear Valley Solar Observatory

Facing the Morning Sun

The Eagles favorite view looks toward the East where the Sun rises. Sandy and Luna may have fledged 2 weeks earlier than sisters Sunny and Gizmo in the last brood. Sandy was accidentally knocked off her perch by little brother Luna. Then Luna had to spend the night alone and fledged the next day.

The timing may have been turned to the highest good. They both made their way back home where they can use the safety of the nest as their base of operations. Eating fish on a branch is a little tricky. They only have to call on Jackie for home delivery.

They have the best accommodations (with room service). They know they can fly and make their way back, so they are free to come and go.
