High- latitude sky watchers should be alert for auroras especially in the southern hemisphere where winter darkness favors visibility. Free: Aurora Alerts. NOCTILUCENT CLOUD ACTIVITY: Sky watchers in Europe are reporting bright displays of noctilucent clouds (NLCs) this weekend. ![]() In early June, an unexpected heat wave in the mesosphere temporarily wiped out noctilucent clouds. Their return proves that the heat wave is over. Firefighters battled an attic fire that broke out at a strip mall in Mar Vista on Sunday.

THESE PENDANTS HAVE TOUCHED SPACE: Looking for a far- out gift? On April 1. 5, 2. Earth to Sky Calculus flew a payload- full of heart- shaped Venus pendants to the stratosphere onboard a high- altitude helium balloon. Here's one floating 1. Sierras of central California: You can have one for $1. ![]() Each glittering pendant comes with a greeting card showing the jewelry in flight and telling the story of its journey to the stratosphere and back again. More items from the edge of space may be found in the Earth to Sky Store. All proceeds support atmospheric radiation monitoring and hands- on STEM education. Far Out Gifts: Earth to Sky Store.

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. 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 . Cosmic rays can seed clouds, trigger lightning, and penetrate commercial airplanes. 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. Researchers. call it a . D. views of the sun from NASA's Solar and Terrestrial.
