On the evening of Feb. 12th, Hungarian astronomer Krisztian Sarneczky discovered a small asteroid approaching Earth. Less than two hours later, astronomers at the Sormano Astronomical Observatory (SAO) chased it down in the skies of Italy: "Observations by SAO members Testa and Manca helped to precisely determine the asteroid's orbit and trajectory," says astronomer Enrico Colzani. "It was heading for Europe." Four hours later the asteroid struck Earth. On Feb. 13th at 0259 UTC, David Legangneux photographed the fireball from France: "I took this picture 200 km south of the predicted impact zone," says Legangneux. More than 60 eyewitness sightings pinpointed the impact over the English Channel. The 1-meter-wide space rock disintegrated entirely in the atmosphere. This is only the 7th time in history that astronomers spotted an asteroid before it hit Earth. The first was in 2008--and how times have changed. Fifteen years ago, asteroid 2008 TC3 made international headlines when it scattered meteorites across the Nubian Desert in Sudan only 19 hours after its discovery. Last night's impact was widely reported on Twitter but, overall, a lesser sensation. Early warnings are increasingly routine. For the record, previous asteroids detected just before they hit Earth are: 2008 TC3, 2014 AA, 2018 LA, 2019 MO, 2022 EB5 and 2022 WJ1.

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 Feb 14 2023, 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] 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 February 14, 2023 there were 2330 potentially hazardous asteroids. | Recent & Upcoming Earth-asteroid encounters: Asteroid | Date(UT) | Miss Distance | Velocity (km/s) | Diameter (m) | 2022 CX1 | 2023-Feb-09 | 17.4 LD | 13.2 | 14 | 2023 CR | 2023-Feb-09 | 2.2 LD | 8.1 | 9 | 2023 CF1 | 2023-Feb-09 | 8.7 LD | 5.8 | 9 | 2023 CA1 | 2023-Feb-09 | 5.7 LD | 12 | 24 | 2023 CA2 | 2023-Feb-09 | 14.9 LD | 12.6 | 52 | 2023 CB1 | 2023-Feb-10 | 6.9 LD | 7.1 | 15 | 2023 CQ | 2023-Feb-10 | 1.5 LD | 9.2 | 10 | 2023 CY2 | 2023-Feb-10 | 2.8 LD | 12.6 | 9 | 2023 BC8 | 2023-Feb-11 | 15.5 LD | 14 | 51 | 2023 CY | 2023-Feb-11 | 8 LD | 11 | 19 | 2023 CK2 | 2023-Feb-12 | 15.6 LD | 20.6 | 104 | 2023 CL1 | 2023-Feb-12 | 2.2 LD | 10.9 | 12 | 2023 CJ1 | 2023-Feb-13 | 12.5 LD | 7.2 | 27 | 2021 EP4 | 2023-Feb-13 | 19 LD | 6.1 | 5 | 2023 CU1 | 2023-Feb-14 | 5.7 LD | 8.6 | 15 | 2023 CH2 | 2023-Feb-14 | 1.1 LD | 10.1 | 19 | 2023 CP | 2023-Feb-14 | 17.2 LD | 3.4 | 36 | 2023 CZ1 | 2023-Feb-14 | 17.7 LD | 8.6 | 14 | 2023 CP2 | 2023-Feb-14 | 2.9 LD | 5.1 | 9 | 2023 CN2 | 2023-Feb-15 | 4.6 LD | 9.7 | 10 | 2023 CT1 | 2023-Feb-15 | 2.2 LD | 16.9 | 18 | 199145 | 2023-Feb-16 | 12 LD | 24.6 | 770 | 2023 CF2 | 2023-Feb-16 | 3.9 LD | 7.9 | 8 | 2023 CV1 | 2023-Feb-16 | 10.7 LD | 7.3 | 38 | 2023 CJ2 | 2023-Feb-16 | 6.8 LD | 8.2 | 30 | 2022 RG | 2023-Feb-16 | 8.2 LD | 3 | 25 | 2023 CG2 | 2023-Feb-16 | 1.3 LD | 21.3 | 14 | 2023 CY1 | 2023-Feb-17 | 4.6 LD | 6.7 | 20 | 2023 CW2 | 2023-Feb-17 | 1.6 LD | 2.3 | 5 | 2020 DG4 | 2023-Feb-17 | 1.4 LD | 6.9 | 8 | 2023 CC1 | 2023-Feb-18 | 15 LD | 12.2 | 41 | 2023 CS2 | 2023-Feb-18 | 4.3 LD | 7.6 | 9 | 2023 CE2 | 2023-Feb-18 | 13.7 LD | 16.1 | 28 | 2023 CH1 | 2023-Feb-18 | 7.6 LD | 7.5 | 16 | 2023 CW | 2023-Feb-18 | 6.6 LD | 7.6 | 25 | 2020 CX1 | 2023-Feb-19 | 17.4 LD | 7.7 | 53 | 2023 CR2 | 2023-Feb-20 | 19.3 LD | 17.4 | 21 | 37638 | 2023-Feb-21 | 17 LD | 11.1 | 493 | 2023 AA2 | 2023-Feb-22 | 17.4 LD | 10.1 | 133 | 2023 CM2 | 2023-Feb-22 | 2.1 LD | 11.3 | 21 | 2023 CS1 | 2023-Feb-23 | 15.1 LD | 9.1 | 30 | 2023 CG1 | 2023-Feb-25 | 15.2 LD | 6.5 | 32 | 2023 CX2 | 2023-Feb-27 | 7.6 LD | 2.3 | 11 | 2023 CC2 | 2023-Feb-27 | 16.2 LD | 5.1 | 31 | 2012 DK31 | 2023-Feb-27 | 12.6 LD | 15.5 | 143 | 2006 BE55 | 2023-Feb-28 | 9.4 LD | 13.3 | 145 | 2021 QW | 2023-Mar-03 | 13.9 LD | 12.1 | 79 | 2017 BM123 | 2023-Mar-03 | 12.1 LD | 7.8 | 61 | 2007 ED125 | 2023-Mar-03 | 11.7 LD | 13.1 | 224 | 2015 EG | 2023-Mar-04 | 13.9 LD | 10.6 | 27 | 2023 BK5 | 2023-Mar-05 | 17.8 LD | 8.4 | 62 | 535844 | 2023-Mar-07 | 10.5 LD | 7.7 | 149 | 2020 FQ | 2023-Mar-09 | 14 LD | 6.3 | 13 | 2020 FV4 | 2023-Mar-13 | 17.6 LD | 8.2 | 30 | 2023 CM | 2023-Mar-14 | 10.3 LD | 14 | 190 | 2018 UQ1 | 2023-Mar-17 | 10.7 LD | 11.7 | 143 | 2016 WH | 2023-Mar-19 | 18.1 LD | 11.8 | 14 | 2018 FE3 | 2023-Mar-21 | 10.1 LD | 5.4 | 13 | 2022 YK4 | 2023-Mar-29 | 11.9 LD | 2.3 | 25 | 2017 SE12 | 2023-Mar-30 | 5.2 LD | 8.4 | 15 | 2016 GH1 | 2023-Mar-30 | 7.7 LD | 5.8 | 11 | 2022 GO3 | 2023-Apr-02 | 17 LD | 11.6 | 15 | 2021 GN1 | 2023-Apr-02 | 17.7 LD | 14.2 | 18 | 2018 FD | 2023-Apr-07 | 17.9 LD | 8.2 | 47 | 2019 GK21 | 2023-Apr-13 | 15.2 LD | 8.1 | 27 | 2022 YK9 | 2023-Apr-13 | 19.9 LD | 9.9 | 175 | 436774 | 2023-Apr-13 | 12.5 LD | 17.6 | 719 | Notes: LD means "Lunar Distance." 1 LD = 384,401 km, the distance between Earth and the Moon. 1 LD also equals 0.00256 AU. | Cosmic Rays in the Atmosphere | SPACE WEATHER BALLOON DATA: Almost 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 sensors that detect secondary cosmic rays, a form of radiation from space that can penetrate all the way down to Earth's surface. Our monitoring program has been underway without interruption for 7 years, resulting in a unique dataset of in situ atmospheric measurements. Latest results (July 2022): Atmospheric radiation is decreasing in 2022. Our latest measurements in July 2022 registered a 6-year low: What's going on? Ironically, the radiation drop is caused by increasing solar activity. Solar Cycle 25 has roared to life faster than forecasters expected. The sun's strengthening and increasingly tangled magnetic field repels cosmic rays from deep space. In addition, solar coronal mass ejections (CMEs) sweep aside cosmic rays, causing sharp reductions called "Forbush Decreases." The two effects blend together to bring daily radiation levels down. .Who cares? Cosmic rays are a surprisingly "down to Earth" form of space weather. They can alter the chemistry of the atmosphere, trigger lightning, and penetrate commercial airplanes. According to a study from the Harvard T.H. Chan school of public health, crews of aircraft have higher rates of cancer than the general population. The researchers listed cosmic rays, irregular sleep habits, and chemical contaminants as leading risk factors. A number of controversial studies (#1, #2, #3, #4) go even further, linking cosmic rays with cardiac arrhythmias and sudden cardiac death. Technical notes: 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. Data points in the graph labeled "Stratospheric Radiation" 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 Regener and Georg Pfotzer discovered the maximum using balloons in the 1930s and it is what we are measuring today. | The official U.S. government space weather bureau | | The first place to look for information about sundogs, pillars, rainbows and related phenomena. | | Researchers call it a "Hubble for the sun."
