Subscribe to Space Weather News!  SOLAR ACTIVITY: On Wednesday, June 13th, sunspot group 9502 unleashed a strong M7-class solar flare. The eruption propelled a coronal mass ejection (CME) into space from the Sun's east limb (the cloud is not heading for Earth). The face of the Sun is peppered with spots, and forecasters estimate a 50% chance of additional M-class flares during the next 24 hours. Above: The ESA/NASA Solar and Heliospheric Observatory captured this coronagraph movie of Wednesday's CME billowing away from sunspot 9502.
THE BIGGEST EXPLOSIONS IN THE SOLAR SYSTEM: NASA's HESSI spacecraft aims to unravel an explosive mystery: the origin of solar flares. [full story]  RADIO METEORS: The annual Arietid meteor shower peaked on Thursday, June 7th. The Arietids are unusual because they are daytime meteors -- most of them streak through the sky unnoticed while the bright Sun is overhead. Nevertheless, you can listen to the elusive Arietids (the shower remains active until early July) by tuning in to NASA's online meteor radar. Radio meteor listener Stan Nelson captured this radar echo from an Arietid that passed above the Naval Space Surveillance Radar on June 7th. [FULL STORY]

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 are on a collision course with our planet, although astronomers are finding new ones all the time. [more]
On 14 Jun 2001 there were 310 known Potentially
Hazardous Asteroids May-June 2001 Earth-asteroid encounters | ASTEROID | DATE (UT) | MISS DISTANCE | | 2001 FE90 | 2001-May-06 23:37 | 49.7 LD | | 1999 KW4 | 2001-May-25 23:31 | 12.6 LD | | 2001 JV1 | 2001-Jun-06 07:53 | 18.0 LD | Note: LD is a "Lunar Distance." 1 LD = 384,401 km, the distance between Earth and the Moon. 1 LD also equals 0.00256 AU.
