Each year some 20,000 Chinese immigrants arrive in New York from Taiwan and Hong Kong. Years later, meteorite hunters are still finding pieces of the Chelyabinsk asteroid that rained down after its 1. A similar asteroid is approaching Earth this week, but this time NASA knows its coming. TC4 measures somewhere between 1. Oct. 1. 2th it will pass 4. Moon. The flyby is so close, Earths gravity will significantly alter the asteroids trajectory before it exits the Earth Moon system. Above An artists concept of the 2. TC4 near Earth flyby. We know the orbit of 2. TC4 well enough to be absolutely certain that it wont hit Earth, says Paul Chodas, manager of the Center for Near Earth Object Studies CNEOS at JPL,but we havent established its exact path just yet. To get a better handle on the asteroids orbit and possible future encounters, an international network of telescopes will monitor 2. TC4 as it goes by. Pinging the asteroid with its Goldstone radar, NASA hopes to learn much about the space rocks physical properties. The space agency will even exercise some aspects of its planetary defense systems. This asteroid is too small to see with the naked eye. However, skilled amateur astronomers using 8 inch telescopes will be able to observe it. At peak brightness, 2. TC4 will shine like a 1. Capricornus and Sagittarius, according to Astro. Bob, who has detailed observing tips. Above 2. 01. 2 TC4 approaching Earth on Oct. Photo credit Mike Olason of Denver COGot a picture of 2.

I grabbed my camera and zoomed in for a closer look. This is what he saw The rainbows primary red band had separated from the rest says Larsen. What happened Atmospheric optics expert Les Cowley says there are at least two ways that rainbows can be distorted in this way First, by hot air This rainbow over Adelaide, Australia, was bent by columns of rising hot city air, but no cities appear to be near Jon Larsens rainbow, says Cowley. Second, by mixed up raindrops Rainbows can appear distorted when there are differences in the size of the raindrops along lines of sight to different parts of the bow. Small drops give broader bows. The second explanation is probably correct. Larsen notes that strong surface winds were blowing rain shafts around. These strong winds may have segregated raindrops into layers of different size small drops being blown about more easily than large ones giving the bow a strange appearance, indeed.

Wyoming and Nebraska This video was assembled and edited by filmmaker Ginger Perez, a founding student member of Earth to Sky Calculus. The payload was sponsored by the Southern Maine Community College with Maine students joining the launch team as space weather balloon trainees. Our next solar eclipse mission is already set We plan to launch space weather balloons from Chile into a total eclipse on July 2, 2. That one will be a sunset eclipse with the sun low on the horizon during the flight. The teams are looking forward to photographing the Moons stretched out shadow fringed by lovely sunset colors.

Readers, thank you for your patience while we continue to develop this new section of Spaceweather. Weve 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 2. At 4. 0,0. 00 feet, the multiplier is closer to 5. 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. 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 1. 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 Earths 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 1. V to 2. 0 Me. V. 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 6.
