The Perseids

Just finished my Perseid Skywatch for the night-looked out between 01.00 and 02.00 and got to see 10 Meteors giving a ZHR of +/- 10
I also noticed the Perseid Meteors that went to the East from my area out to sea and making flashes on the Horizon-I wondered if it was to do with these hot pieces of space dust hitting the sea at high speed and causing a flash of some kind that looked like lightning?

Although this could have actually been lightning as it can be seen as far away as Greece from the U.K.

A lot of rain today making it very damp and exceptionally wet on the grass outside-quite a bit of haze in the sky reflecting the orange glow of the streetlights around my Village making seeing conditions down to around Magnitude +1 to +2 stars to be seen with the unaided eye so not a brilliantly clear sky.

I went outside again @ 02,40 until 03.20 and only got to see 1 giving a ZHR that time roughly +/- 1 so the Meteor activity had waned a little as the Constellation of Perseus had risen a little higher in the North East in the early hours.

See the ISS pass over @ 03.16 as it came out of the shadow around 31 Degrees up and fell into the Eastern Morning sky-now waiting for its 04.48 pass which will be a better pass of 74 Degrees if the thin clouds disperse by then in my area but they seem to be getting thicker all the time.
I will be looking tomorrow if the sky is clear so GCS... Very Happy

Incoming CME could spark high-latitude auroras

Space Weather News for August 9, 2010
http://spaceweather.com

INCOMING CME: The solar eruption of August 7th might affect Earth after all. Newly-arriving data from the Solar and Heliospheric Observatory (SOHO) show a CME heading our way with a significant Earth-directed component. High-latitude sky watchers should be alert for auroras when the cloud arrives on August 10th. A movie of the CME is featured on today's edition of http://spaceweather.com.

EARLY PERSEID METEORS:  The Perseid meteor shower doesn't peak until August 12th, but already late-night sky watchers are seeing a nice display of shooting stars.  Observers are counting as many as 20 Perseids per hour from dark sky sites, a number that could increase 3- to 5-fold before the week is over.  Visit
http://spaceweather.com for more information.

An unexpected ammonia leak and a jammed quick-disconnect fitting disrupted
an eight-hour spacewalk Saturday to replace a faulty coolant system pump
on the International Space Station. Assuming engineers can come up with a
quick fix for the leak, the astronauts may attempt to replace the pump
during a second spacewalk Wednesday.

Solar Blast Just Misses Earth

Space Weather News for August 8, 2010
http://spaceweather.com

SOLAR BLAST JUST MISSES EARTH: On Saturday, August 7th, magnetic fields around sunspot 1093 erupted.  NASA spacecraft and many amateur astronomers photographed the blast, which produced a strong M1-class solar flare and hurled a coronal mass ejection (CME) into space--apparently just missing the sun-Earth line. The explosion also made whooshing sounds in the loudspeakers of some shortwave radios. Visit http://spaceweather.com for audio recordings and movies of this latest solar event.

AURORA RECAP:  Last week's geomagnetic storm sparked Northern Lights as far south as Iowa in the United States, and some nice Southern Lights over Antarctica.  For the latest images, start browsing here:

North Polar Layers of Mars

North Polar Layers of Mars
Wed, 04 Aug 2010 23:00:00 -0500

The north polar layered deposits are layers of dusty ice up to 2 miles thick and approximately 620 miles in diameter. We can see the layers exposed on the walls of troughs and scarps cut into the deposits, such as the trough wall imaged here. The bright region at the top is the flat surface above the trough wall; it is higher than the terrain underneath. The wall exposing these layers has a vertical relief of about 1970 feet. It is thought that the north polar layered deposits likely formed recently (i.e., millions of years ago) as rhythmic variations in Mars' orbit changed the distribution of water ice around the planet. As ice moved to and from the polar region in response to a changing climate, layers of ice and dust built up at the poles. By studying the history of these deposits, we hope to understand how the Martian climate has changed, similar to how scientists on Earth study ice cores from the North and South Poles. Three things are immediately apparent about the layers exposed on this trough face. First, individual layers have different surface textures, which some scientists believe could reflect changing physical properties (such as dust content or ice grain size) of the underlying layer. Second, there are several unconformities, or places where one layer is interrupted and overlain by another layer. These unconformities are due to periods where layers were eroded or removed, followed by times when new layers were deposited. Mapping the locations of unconformities can tell us how the deposit shrank and grew over time, and tell us where large changes in climate occurred, causing water ice to be removed from the polar regions. Finally, the dark and bright streaks are due to recent winds blowing surface frost around, and can tell us about wind patterns in the current polar climate. This was imaged by the HiRISE camera onboard the Mars Reconnaissance Orbiter. HiRISE is the most powerful camera of its kind ever sent to another planet. Its high resolution allows us to see Mars like never before and could help other missions choose a safe spot to land for future exploration. Credit: NASA/JPL/University of Arizona

What's Up for August? 03/08/10

What's Up for August? The Perseid meteor shower.
 
Hello and welcome. I'm Jane Houston Jones at NASA's Jet Propulsion Laboratory in Padadena, California.
 
If you've never seen a meteor shower, this month's Perseids are a perfect introduction.
 
Plan a summer getaway on Thursday night August 12. You'll begin to see meteors by about 11 p.m. But the rates increase closer to dawn.
 
The Perseid meteor shower is named after the constellation Perseus. And the meteors appear to originate near this constellation in the northeast sky.
 
This year's meteor shower happens on a moonless night, so you'll be able to see more of the fast, bright meteors.
 
Meteor showers are the debris of a passing comet, or sometimes the debris from a fragmented asteroid. Comets originally formed in the cold outer solar system, while most of rocky asteroids formed in the warmer inner solar system between the orbits of Mars and Jupiter.
 
When a comet nears the sun, its icy surface heats up. This causes clouds of gas, dirt and dust to be released, forming a tail of debris that can stretch for millions of miles. As Earth passes near this dusty tail, some of the particles hit our atmosphere. They burn up and we see the result as meteors.
 
NASA generates meteor shower forecasts to prevent potential hazards to spacecraft that are launching and orbiting Earth.
 
You'll see some Perseids all month long, before and after midnight. But the best fireworks display will be in the wee hours of Friday morning August 13.
 
The European Space Agency's comet mission Rosetta flew by asteroid Lutetia last month and returned beautiful images of this battered world.
 
Now Rosetta's on its way to send a lander to a comet.
 
NASA's Deep Impact EPOXI spacecraft is on an extended mission to study and search for planets orbiting distant stars. But first, in early November this year, it will fly by Comet Hartley 2.
 
NASA's Stardust NExT mission will fly by Comet Tempel 1 in 2011. And the Dawn mission arrives at asteroid Vesta in 2011, and the dwarf planet Ceres in 2015.
 
Despite that recurring email hoax about Mars being big and bright this month, it appears as a faint, reddish object near brighter Venus and Saturn just at sunset.
 
Jupiter shines as a brilliant beacon nearly overhead before midnight.
 
Through a telescope you might be able to see nearby Uranus.

That's all for this month. I'm Jane Houston Jones.

CME impact sparks geomagnetic storm

Space Weather News for August 3, 2010
http://spaceweather.com

CME IMPACT: As expected, a coronal mass ejection (CME) hit Earth's magnetic field on August 3rd.  The impact, which occurred around 1730 UT, sparked a polar geomagnetic storm.  At the time that this alert is being written, sky watchers in Europe as far south as Germany are reporting red and green Northern Lights.  If the storm sustains itself for a few more hours, people in North America might see a similar display. Sky watchers in Alaska, Canada, and northern-tier US states such as Wisconsin, Minnesota and Maine should be alert for auroras.
