What's up in space
       
 

Solar minimum is here - but even now strangely beautiful auroras are dancing around the poles. Deep inside the Arctic Circle, the expert guides of Aurora Holidays in Utsjoki, Finland, can help you chase them. Book now!

 

CHANCE OF STORMS: NOAA forecasters say there is a 60% chance of G1-class geomagnetic storms on Jan. 24th when a stream of solar wind is expected to hit Earth's magnetic field. The gaseous material is flowing ~600 km/s from a hole in the sun's atmosphere. Arctic auroras are likely this Thursday. Aurora Alerts: SMS text, email.

THE BLUE LUNAR ECLIPSE: Lunar eclipses are supposed to be red, yet when the Moon passed through Earth's ruddy shadow on Jan. 20th, many observers witnessed a different color: turquoise blue. Heiko Ulbricht and Dirk Landrock photographed  the phenomenon from Radebeul, Germany:

"The colors were wonderful--red and blue," says Ulbricht.

The source of the turquoise is ozone. Prof. Richard Keen, an atmospheric scientist from the University of Colorado explains: "During a lunar eclipse, most of the light illuminating the Moon passes through the stratosphere, and is reddened by scattering. However, light passing through the upper stratosphere penetrates the ozone layer, which absorbs red light and actually makes the passing light ray bluer." This can be seen, he says, as a turquoise fringe around the red.

Blue appears during every total eclipse of the Moon. Naked-eye observers often miss it because it is fleeting, best seen only during the opening and closing minutes of totality. Binoculars and telescopes improves visibility. "We used a 14-inch Maksutov-Newton telescope," notes Ulbricht.

The blue eclipse was also seen in Argentina, Arizona, Oklahoma, Illinois, Italy, the Netherlands, and Kansas ... just to name a few.

SPACE WEATHER ALERTS: Spaceweather.com is proud to announce our new and improved space weather alert system. Sign up now and you'll never miss another solar storm in 2019. Subscribers receive instant text messages when there are solar flares, geomagnetic storms, and CMEs about to strike Earth. And if you sign up for the PRO PLAN, you'll receive a type of alert available no where else--"Magnetic Crack" alerts. Keep reading after the graphic to learn more:

PRO PLAN subscribers get a text message whenever a crack is opening in Earth's magnetosphere. Magnetic cracks are caused by south-pointing magnetic fields ("BsubZ") in the solar wind, which partially cancel Earth's magnetic defenses. Solar wind pours in through these cracks to fuel bright auroras and geomagnetic storms. Veteran aurora chasers know that watching "BsubZ" is the best way to anticipate geomagnetic activity. Now your cell phone can do this job for you, alerting you when cracks are forming in the invisible magnetic field overhead.

Get started for as little as $4.95 per month.

  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. 21, 2019, the network reported 10 fireballs.
(10 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 January 22, 2019 there were 1947 potentially hazardous asteroids.

  Cosmic Rays in the Atmosphere

SOMETHING NEW! We have developed a new predictive model of aviation radiation. It's called E-RAD--short for Empirical RADiation model. We are constantly flying radiation sensors onboard airplanes over the US and and around the world, so far collecting more than 22,000 gps-tagged radiation measurements. Using this unique dataset, we can predict the dosage on any flight over the USA with an error no worse than 15%.

E-RAD lets us do something new: Every day we monitor approximately 1400 flights criss-crossing the 10 busiest routes in the continental USA. Typically, this includes more than 80,000 passengers per day. E-RAD calculates the radiation exposure for every single flight.

The Hot Flights Table is a daily summary of these calculations. It shows the 5 charter flights with the highest dose rates; the 5 commercial flights with the highest dose rates; 5 commercial flights with near-average dose rates; and the 5 commercial flights with the lowest dose rates. Passengers typically experience dose rates that are 20 to 70 times higher than natural radiation at sea level.

To measure radiation on airplanes, we use the same sensors we fly to the stratosphere onboard Earth to Sky Calculus cosmic ray balloons: neutron bubble chambers and X-ray/gamma-ray Geiger tubes sensitive to energies between 10 keV and 20 MeV. These energies span the range of medical X-ray machines and airport security scanners.

Column definitions: (1) The flight number; (2) The maximum dose rate during the flight, expressed in units of natural radiation at sea level; (3) The maximum altitude of the plane in feet above sea level; (4) Departure city; (5) Arrival city; (6) Duration of the flight.

SPACE WEATHER BALLOON DATA: 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 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 18% since 2015:

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.

En route to the stratosphere, our sensors also pass through aviation altitudes:

In this plot, 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.

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.

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.
