Space Weather Update: 01/28/2017

By Spaceweather.com, 01/28/2017

WEEKEND AURORA WATCH: This weekend, a solar wind stream is gently buffeting Earth's magnetic field. As a result, NOAA forecasters estimate a 40% chance of polar geomagnetic storms on Jan. 28th. Arctic sky watchers should be alert for auroras. [realtime photo gallery]

SUPERCOOLED RAINBOW: When the temperature dips below freezing, rainbows vanish, right?  Rainbows require liquid raindrops, and frozen water doesn't do the trick. Yesterday in Alaska, however, a rainbow appeared that seemed to defy the simple laws of physics. John Dean photographed the pale arc over Nome:

 

"It was not raining," says Dean. "The temperature was 25 F and a light snow storm had just passed through about an hour before. This is a first for me, and it has me perplexed."

Atmospheric optics expert Les Cowley explains what happened: "This is definitely a rainbow made by water drops, even though it was so cold. Ice spheres, hail or snowflakes cannot make them because a rainbow needs almost perfectly spherical, smooth and transparent water drops. This bow is broad, telling us that the water drops were small. They were also probably quite high up, and might even have been supercooled below the normal freezing point of water."

Supercooled raindrops can form when droplets of water fall through layers of subfreezing air. Droplets containing specks of dust or even microbes readily freeze as ice crystals form around the impurities.  But when rain droplets are especially pure, they can remain in a liquid state even when the temperature drops below freezing.

Hence -- the "supercooled rainbow." High latitude sky watchers should be alert for these rare rainbows as strange Arctic weather grips the North in winter 2017.

POLAR STRATOSPHERIC CLOUDS: Earth's stratosphere is normally free of clouds. Not this weekend, though. Observers in northern parts of Scandinavia are reporting an outbreak of brilliantly-colored icy clouds in the typically dry and transparent layer of our planet's atmosphere. Truls Tiller sends this picture from Tromsø, Norway:

 

"Amazing view!" he says.

These icy clouds are a sign of very cold temperatures. For ice crystals to form in the arid stratosphere, temperatures must drop to around -85º C. High-altitude sunlight shining through tiny ice particles ~10µm across produce the characteristic bright iridescent colors.

Once thought to be mere curiosities, some polar stratospheric clouds (PSCs) are now known to be associated with the destruction of ozone. Indeed, an ozone hole formed over the UK in Feb. 2016 following an outbreak of ozone-destroying Type 1 PSCs.

FAR-OUT VALENTINE'S GIFT: To raise money for their cosmic ray ballooning program, the students of Earth to Sky Calculus have flown a payload-full of Valentine's pendants to the edge of space--and you can have one for $89.95. Buy one this week and we will include a space rose free of charge.

 

Each glittering pendant comes with a greeting card showing the jewelry in flight and certifying that it has been to the stratosphere and back again.

More far-out Valentine's gifts may be found in the Earth to Sky store. All proceeds support cosmic ray balloon flights and STEM education.

ALTERNATE AURORAS: On Jan. 24th, photographer Dave Bell of Pinedale, Wyoming, witnessed a display of colorful lights in the sky. They looked liked auroras--but they were not. 

 

They're light pillars, caused by ice crystals in the air which intercept urban lights and spread them into colorful columns. Sometimes called "false auroras," no solar activity is required for the phenomenon. The only ingredients are ice and light pollution

"We had a really terrific snowstorm in Pinedale for 36 hours," says Bell. "As the storm cleared and temperatures plummeted, fine crystals of ice filled the air and we were treated to a spectacular display of pillars. A friend recently commented that light pillars are like our version of the aurora borealis."

 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 Spaceweather.com.

On Jan. 28, 2017, the network reported 22 fireballs.
(22 sporadics)

 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 January 28, 2017 there were 1766 potentially hazardous asteroids.

 Cosmic Rays in the Atmosphere

 

Readers, thank you for your patience while we continue to develop this new section of Spaceweather.com. 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, Spaceweather.com 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.
