INCREASING CHANCE OF FLARES: NOAA forecasters have boosted the odds of an M-class solar flare today to 60%. There are two sunspots capable of producing such flares, AR2104 and<br />
AR2107, and both are turning toward Earth. Solar flare alerts: text, voice<br />

<br />
NOCTILUCENT OUTBURST: Sky watchers in Europe are reporting an outburst of bright noctilucent clouds (NLCs). The display began at sunset on<br />
July 3rd, filling northern horizons with electric-blue ripples, swirls, and tendrils of light. Morten Ross sends this picture from Sandbukta, Norway:<br />
<br />
<br />
<br />
<br />
<br />
"An incredibly bright and widespread display - from northern horizon to zenith!" says Ross. "This is only the third night of July and its already much better than last year." Similar reports have<br />
come from France, Germany, Poland, the Netherlands, Scotland, Ireland, England and Belgium.<br />
<br />
<br />
Although most of the reports so far have come from Europe, the nights ahead could bring NLCs to North America as well. Monitor the realtime gallery for updates:<br />

<br />
NLCs are Earth's highest clouds. Seeded by "meteor smoke," they form at the edge of space 83 km above<br />
Earth's surface. When sunlight hits the tiny ice crystals that make up these clouds, they glow electric blue.<br />
<br />
<br />
NLCs appear during summer because that is when water molecules are wafted up from the lower atmosphere to mix with the meteor smoke. That is also, ironically, when the upper atmosphere is<br />
coldest, allowing the ice crystals of NLCs to form.<br />
<br />
<br />
The natural habitat of noctilucent clouds is the Arctic Circle. In recent years, however, they have spread to lower latitudes with sightings as far south as Utah and Colorado. This will likely<br />
happen in 2014 as well. Observing tips: Look west 30 to 60 minutes after sunset when the Sun has dipped 6o to 16o below the horizon. If you see luminous blue-white tendrils spreading across the sky, you may have spotted a noctilucent cloud.<br />
<br />
<br />
MONSTER ASTEROIDS CONVERGE: The two most massive objects in the asteroid belt, dwarf planet Ceres and minor planet Vesta, are converging for a close encounter in the night sky<br />
on July 4th and 5th. Last night in Italy, Gianluca Masi used a remotely operated telescope to photograph the monster asteroids only 13 arcminutes apart--less than half the width of a full Moon.<br />
The line splitting the two is a terrestrial satellite:<br />
<br />
<br />
<br />
<br />
<br />
At closest approach on July 5th, the two asteroids will be only 10 arcminutes apart in the constellation Virgo. They are too dim to see with the unaided eye, but easy targets for binoculars and<br />
small telescopes. Observing tips are available from Sky and Telescope.<br />
<br />
<br />
Got clouds? You can watch the close encounter online. Choose between Gianluca Masi's Virtual Telescope Project (which begins July 5th at 4:00 p.m. EDT) or Slooh's webcast (July 3rd at 8 p.m. Eastern Daylight Time).<br />
<br />
<br />
Quite near the two asteroids on the sky, though utterly invisible, is NASA's Dawn spacecraft. Dawn recently finished visiting Vesta and is now en route to Ceres. The ion-propelled spacecraft will<br />
enter orbit around Ceres next March. Cameras on Dawn will resolve the pinprick of light you see this weekend into a full-fledged world of unknown wonders. Stay tuned for that!<br />

Every night, a network of NASA all-sky cameras scans the skies above the United States for meteoritic fireballs. Automated software maintained by<br />
NASA's Meteoroid Environment Office calculates their orbits, velocity, penetration depth in Earth's atmosphere and many other characteristics. Daily results are presented here on<br />
Spaceweather.com.<br />
<br />
<br />
On Jul. 3, 2014, the network reported 14 fireballs.<br />
( 14 sporadics)<br />

In this diagram of the inner solar system, all of the fireball orbits intersect at a single point--Earth. The orbits are color-coded by velocity, from slow (red) to fast (blue). [Larger image] [movies]<br />

Potentially Hazardous Asteroids (PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the<br />
known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time.<br />

Planet Earth reaches its most distant point from the sun for 2014 on July 4 – American Independence Day 2014 – at 0 hours UTC). That’s 7 p.m. Central Daylight Time in the<br />
U.S. on July 3. And it’s sort of an independence day for Earth, too. Woot, woot! Farthest from the sun! <br />
So why is it so hot outside for us in the N. Hemisphere?<br />
<br />
<br />
Earth’s independence is limited and temporary. That’s because our world’s orbit is very nearly circular. We’re not that much farther away from the sun on July 3-4 than we ever are. Today, we’re<br />
about three million miles (five million kilometers) farther from the sun than we will be six months from now. That’s in contrast to our average distance from the sun of about 93 million miles<br />
(150 million km).<br />
<br />
<br />
Astronomers call this point in Earth’s orbit its aphelion. The word aphelion comes from the Greek words apo meaning away, off, apart and helios (for the<br />
Greek god of the sun). Apart from the sun. That’s us, today.<br />
<br />
<br />
Looking for Earth’s exact distance from the sun at aphelion? It’s 94,506,462 miles (152,093,481 km). Last year, on July 5, 2013, the Earth at aphelion was a tiny bit farther away, at 94,508,959<br />
miles (152,097,427 km).<br />

This illustration greatly exaggerates the eccentricity – or oblongness – of Earth’s orbit, but you get the idea.<br />

<br />
<br />
<br />
Why is it so hot outside for us in the N. Hemisphere? We’re always farthest from the sun in early July during a N. Hemisphere summer – and closest in January during a N.<br />
Hemisphere winter – and that’s a good illustration of the fact that it’s not the Earth’s distance from the sun that creates the seasons on our world.<br />
<br />
<br />
Instead, the seasons result from Earth’s tilt on its axis. Right now, it’s summer in the Northern Hemisphere because the northern part of Earth is tilted most toward the sun.<br />
<br />
<br />
Meanwhile, it’s winter in the S. Hemisphere because the southern part of Earth is tilted most away from the sun.<br />
<br />
<br />
Okay? Earth’s varying distance from the sun doesn’t create the seasons. But it does affect the length of the seasons. That’s because, at our farthest from the sun, like now, Earth is traveling<br />
most slowly in its orbit. That makes summer the longest season in the N. Hemisphere and winter the longest season on the southern half of the globe.<br />
<br />
<br />
Conversely, winter is the shortest season in the N. Hemisphere and summer is the shortest in the S. Hemisphere – in each instance, by nearly 5 days.<br />
<br />
<br />
Happy Earth independence day, y’all!<br />

Bottom line: Planet Earth reaches its most distant point from the sun for 2014 on July 4 at 0 hours UTC).<br />
That’s 7 p.m. Central Daylight Time on July 3, here in the U.S. Astronomers call this yearly point in Earth’s orbit our aphelion.<br />
