New sunspot AR1598 has erupted again. On Oct. 23rd at 0322 UT, Earth orbiting satellites detected a strong X1-class solar flare. NASA’s Solar Dynamics Observatory recorded the extreme ultraviolet flash: movie.
Radiation from the flare created waves of ionization in the upper atmosphere over Asia and Australia (the daylit side of Earth) and possibly HF radio blackouts at high latitudes. The blast did not, however, produce a significant coronal mass ejection (CME). No auroras are expected to result from this event.
This is the 4th significant flare from AR1598 since it emerged over the southeastern limb only three days ago. This means more flares are probably in the offing, and they will become increasingly Earth-directed as the sunspot turns toward our planet in the days ahead. Stay tuned for updates.
Look out for the Meteor shower, in the Orionid!!! South west of the brightest star in the sky, which is our planet Jupiter! 🙂
An Austrian daredevil hopes to make a new record-breaking attempt Sunday to jump from the edge of space, days after his initial bid was aborted at the last minute due to gusting winds.
Felix Baumgartner will be transported up to 23 miles above the Earth beneath an enormous balloon, before launching himself into the void, aiming to become the first human to break the sound barrier in free fall.
After an extended delay do to gusty weather, it is hoped that on Sunday, Oct. 14, 2012, daredevil Felix Baumgartner will be carried high above Roswell, N.M., in an attempt to break the high-altitude skydive record that was set 52 years ago by U.S. Air Force Captain Joe Kittinger. Discovery Channel and Discovery News will be covering the event LIVE. Follow this special Wide Angle investigating the history of high-altitude skydives, some of the technology involved in Baumgartner’s record attempt and links to our live coverage on the day.
Asteroid — 2012 TC4 — is going to fly past the Earth at a distance of only 95,000 kilometers (59,000 miles), or one-quarter the Earth-moon distance. As far as near-misses go, that’s the outer edge of the bulls-eye!!!
This is not a Potentially Hazardous Asteroids (PHAs). Those 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.
We need as many eyes out there!
