Cosmic Rays Solar minimum is underway. The sun's magnetic field is weak, allowing extra cosmic rays into the solar system. Neutron counts from the University of Oulu's Sodankyla Geophysical Observatory show that cosmic rays reaching Earth in 2019 are near a Space Age peak.

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!

 

SOLAR WIND, INCOMING: A minor stream of solar wind is heading toward Earth. Estimated time of arrival: April 4-5. Geomagnetic unrest and Arctic auroras are possible when the gaseous material arrives. Aurora alerts: SMS Text.

VENUS AND THE PLEIADES: If a supernova went off inside the Pleiades star cluster, what would it look like? Tonight, we find out. Venus and the Pleiades are having a rare conjunction, with supernova-bright Venus apparently inside the star cluster on April 3rd. Fred Espenak of Portal, Arizona, captured this preview on April 1st:

"It was beautiful," says Espenak. And it will be even better tonight when the conjunction tightens.

Venus is about 1000 times brighter than the individual stars of the Pleiades. So, when you look at the conjunction with the unaided eye, you mainly see Venus. Try binoculars. Even a small amount of magnification reveals the delicate star cluster surrounding the bright planet. It'll look like a supernova has gone off among the Seven Sisters.

Go outside after sunset, look west, and enjoy the show. Sky maps: April 1, 2, 3.

THE TAIL OF COMET ATLAS: Comet ATLAS (C/2019 Y4) has sprung a tail--and it's impressive. "About 1.2 degrees long," reports Gerald Rhemann, who recorded this animation on March 27th from his backyard observatory in Eichgraben, Lower Austria:

The outer reaches of ATLAS's tail are faint, but the gossamer filaments can be seen sweeping across the stars in Rhemann's animation. Its angular length of 1.2 degrees corresponds to a physical distance of 3.3 million km, or more than twice as wide as the sun.

Comet ATLAS is now shining like an 8th magnitude star--too dim to see with the unaided eye, but an easy target for backyard telescopes. The comet is expected to become much brighter. By the time it sweeps by the sun in late May, it could rival Venus in the evening sky. Stay tuned.

MR. SPOCK IN THE STRATOSPHERE: If you would like to support the Earth to Sky Calculus cosmic ray ballooning program, there's a logical way to do it. Puchase this Mr. Spock collector's item. Here is the green-blooded science officer floating 32.2 km (112,200 ft) above Death Valley National Park in central California:

You can have him for $170.10. The price, in case you're wondering, is the serial number of the Enterprise, NCC1701, divided by 10. The students are selling Spock to buy more helium! He comes with a greeting card showing the high-quality resin bobblehead in flight and telling the story of his journey to the stratosphere and back again.

  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 Apr. 02, 2020, the network reported 12 fireballs.
(12 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 April 3, 2020 there were 2018 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 Regener-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.
