 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.

 Between 7 and 8 p.m.Tuesday night, the sun spit out a large, X5-class solar flare. NOAA’s Space Weather Prediction Center called it “one of the largest solar flares of the current solar cycle.” 
  
 X class flares are the strongest category of solar flares. According to NASA, they can trigger planet-wide radio blackouts and long-lasting radiation storms. 
  
 These flares are often complemented by phenomena known as coronal mass ejections (CME) which are essentially bursts of solar wind. If a CME is directed toward the Earth, a geomagnetic storm results that can interfere with the Earth’s magnetosphere. 
  
 NOAA said predictions for this particular flare/CME event “are still being refined.” 
  
 SpaceWeather.com wouldn’t draw any conclusions about where the CME might go. 
  
 “First-look data from STEREO-B are not sufficient to determine if the cloud is heading for Earth,” it said. 
  
 Its “best guess” was that CME probably won’t directly head for Earth, but rather produce a “glancing blow” on March 8 or 9. 
  
 Here’s a video from NASA showing the flare: 
  
 Via NASA: Right at midnight UT time the active region 1429 unleashed a powerful X5.4-class solar flare. 
  
 A significant solar storm can disrupt satellites, communications systems, and, in some cases, ground-based technologies and power grids. These storms also are conducive to auroras, especially at high latitudes. We will keep you posted on the predictions for this event as they are fine tuned and it draws closer.

A:
The sun blasted out a massive solar flare last night, one that could have the potential to cause blackouts and other problems here on Earth, the Washington Post reports. The flare was an X5-class, the strongest category of flare, and, according to NOAA, "one of the largest solar flares of the current solar cycle." It let out a bright coronal mass ejection, but it's unclear yet if that wave is headed our direction. "Our best guess is, 'probably yes, but not directly toward Earth,'" SpaceWeather.com writes.
