Kjekt å kunne følge med solaktiviteten i tiden fremover. Muligheten for store strømbrudd verden over er jo tilstede da solaktiviteten nærmer seg et høydepunkt.

MINOR STORM WARNING, CANCELLED: A CME expected to sideswipe Earth's magnetic field on August 2nd has not arrived. The tardy cloud is either off target or moving more slowly than forecasters thought, or both. The chance of a geomagnetic storm this weekend is waning. Aurora alerts: textvoice

AMAZING NEW PHOTO OF THE ROSETTA COMET: This weekend the ESA released a new image of Comet 67P/Churyumov-Gerasimenko as seen from the Rosetta probe only 1000 km away. It shows the rough surface of the comet's double nucleus in amazing detail:

The photo was taken on Aug. 1st at 02:48 UTC by Rosetta's OSIRIS Narrow Angle Camera. The dark spot near image-center is an artifact from the onboard CCD.

This new view heightens anticipation for August 6th when Rosetta reaches the comet and goes into orbit around it. Then we will see the strange double-core from point-blank range, and researchers can start to pick touchdown sites for Philae, a lander that will descend to the comet's surface in November.

Only 3 days to rendezvous! Follow the action @ESA_Rosetta.

PLANETS CROSSING AT NOON (UPDATED): This weekend, Jupiter and Mercury are in conjunction. Don't bother looking because the meeting takes place in the noontime sky. What human eyes cannot see, however, spacecraft can. Using an opaque disk to block the glare of the sun, the Solar and Heliospheric Observatory (SOHO) is monitoring the encounter:

At closest approach on August 2nd, the two bright planets were less than 1o apart. If such an alignment occured at night, it would surely be headline news. At noon, its just spaceweather news. Join SOHO for a ringside seat.

  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 Aug. 2, 2014, the network reported 25 fireballs.
(13 sporadics, 5 Perseids, 3 Southern delta Aquariids, 3 alpha Capricornids, 1 August Lyncid)

 

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 August 3, 2014 there were 1497 potentially hazardous asteroids.
