Visit Explore the Arctic METEORS FROM HALLEY'S COMET: The annual Orionid meteor shower is peaking this weekend with rates near 2. Each streak of light emerging from the constellation Orion is a speck of dust from Halley's comet hitting the top of Earth's atmosphere at speeds near 6. The best time to look is during the dark hours before dawn when Orion is high in the sky. [sky map] [photo gallery] ATMOSPHERIC CANYON ON THE SUN: A large hole has opened in the sun's atmosphere, cleaving the Earth- facing side of the sun with a gaseous canyon more than 7. This image, based on data from NASA's Solar Dynamics Observatry, shows the structure directly facing Earth on Oct. This is a coronal hole- -a region where the sun's magnetic field peels back and allows solar wind to escape.

Solar wind is emerging at speeds between 6. When this fast- moving material reaches Earth two days from now, it will likely spark polar geomagnetic storms: G1- class (minor) storms on Oct.

Realtime Space Weather Photo Gallery. VOLCANIC AURUPTION: On Friday night, the most famous mountain in Iceland erupted. Or rather, it aurupted. Photographers  H.+J. Sperr caught a plume of green light spewing from the tip of Kirkjufell: "Auroras dancing behind the iconic peak make it look like a volcanic breakout was in progress," says Sperr who captured the image from the nearby town of Grundarfjördur.

At the time, geomagnetic activity was supposedly low, but the auroras were bright and active anyway."Already one of the most photographed landmarks in Iceland, Kirkjufell gained even more attention in 2. Game of Thrones. And now this..!

Earth to Sky Calculus launched a space weather balloon from the Sierra Nevada mountains of central California. Its mission: to measure cosmic rays at the top of Earth's atmosphere. The payload carried an array of X- ray/gamma- ray detectors, GPS trackers, temperature/pressure sensors and, for fundraising, some pumpkin pendants: This sterling silver pendant ascended to an altitude of 3. After the balloon exploded, as planned, the payload parachuted back to Earth, landing in the Eureka Valley on the outskirts of Death Valley National Park.

We've been working to streamline our data reduction, allowing us to post results from balloon flights much more rapidly, and we have developed a new data product, shown here: This plot displays radiation measurements not only in the stratosphere, but also at aviation altitudes. Dose rates are expessed as multiples of sea level. For instance, we see that boarding a plane that flies at 2.

At 4. 0,0. 00 feet, the multiplier is closer to 5. These measurements are made by our usual cosmic ray payload as it passes through aviation altitudes en route to the stratosphere over California. What is this all about? Approximately once a week, Spaceweather. Earth to Sky Calculus fly space weather balloons to the stratosphere over California. These balloons are equipped with radiation sensors that detect cosmic rays, a surprisingly "down to Earth" form of space weather.

Cosmic rays can seed clouds, trigger lightning, and penetrate commercial airplanes. Furthermore, there are studies ( #1, #2, #3, #4) linking cosmic rays with cardiac arrhythmias and sudden cardiac death in the general population. Our latest measurements show that cosmic rays are intensifying, with an increase of more than 1. Why are cosmic rays intensifying? The main reason is the sun. Solar storm clouds such as coronal mass ejections (CMEs) sweep aside cosmic rays when they pass by Earth. During Solar Maximum, CMEs are abundant and cosmic rays are held at bay.

Now, however, the solar cycle is swinging toward Solar Minimum, allowing cosmic rays to return. Another reason could be the weakening of Earth's magnetic field, which helps protect us from deep- space radiation. The radiation sensors onboard our helium balloons detect X- rays and gamma- rays in the energy range 1. V to 2. 0 Me. V. These energies span the range of medical X- ray machines and airport security scanners.

The data points in the graph above correspond to the peak of the Reneger- Pfotzer maximum, which lies about 6. California. When cosmic rays crash into Earth's atmosphere, they produce a spray of secondary particles that is most intense at the entrance to the stratosphere. Physicists Eric Reneger and Georg Pfotzer discovered the maximum using balloons in the 1. The. official U. S. The. first place to look for information about sundogs.
