Space Weather Update: 03/29/2017

SUNSET SKY SHOW: When the sun goes down tonight, look west into the fading glow of sunset for an exquisitely slender crescent Moon.  It forms a scalene triangle with Mars and Mercury on the edge of the constellation Pisces: sky map.

SOLAR WIND STORM: For the 3rd consecutive day, our planet is inside a stream of fast-moving solar wind flowing from a canyon-shaped hole in the sun's atmosphere. The gaseous material is pressing against Earth's magnetic field with speeds exceeding 600 km/s. Earth's response: A light show around the poles. Last night, Layton Findlater saw the Southern Lights shining through clouds over Invercargill, New Zealand:


"Another night of brief but intense auroras," says Findlater. "Hopefully, we can make it three nights running here in the Deep South."

At the moment, the solar wind shows no sign of flagging. Speeds between 600 and 700 km/s are likely for the rest of March 29th with a 25% chance of G1-class geomagnetic storms. High-latitude sky watchers on both ends of the planet should remain alert for auroras. Free: Aurora Alerts

TOUCHING THE EDGE OF SPACE: On March 10, 2017, the students of Earth to Sky Calculus launched a space weather balloon from the frozen surface of Lake Tornetrask 250 km inside the Arctic Circle. A payload-full of reindeer pendants hitched a ride to the Edge of Space:


You can have one for $129.95.  Each glittering pendant comes with a greeting card showing the jewelry in flight and telling the story of its journey 97,000 feet above the Lapland of Northern Sweden. They make great Birthday and Mother's Day gifts.

More far-out gifts may be found in the Earth to Sky store. All proceeds support STEM education and our atmospheric cosmic ray monitoring program.

 All Sky Fireball Network

Every night, a network of NASA all-sky cameras scans the skies above the United States for meteoritic fireballs. Automated software maintained by 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

On Mar. 29, 2017, the network reported 7 fireballs.
(7 sporadics)



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]


 Near Earth Asteroids

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

On March 29, 2017 there were 1781 potentially hazardous asteroids.

 Cosmic Rays in the Atmosphere


Readers, thank you for your patience while we continue to develop this new section of 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 25,000 feet exposes passengers to dose rates ~10x higher than sea level. At 40,000 feet, the multiplier is closer to 50x. 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, and the students of 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 cloudstrigger 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 12% since 2015:


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 10 keV to 20 MeV. 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 67,000 feet above central 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 1930s and it is what we are measuring today.
