Asteroid Explodes Over Indonesia
Space Weather News for Oct. 28, 2009

INDONESIAN ASTEROID: Earlier this month, with no warning, a ~10-meter wide
asteroid hit Earth's atmosphere above Indonesia and exploded. The break-up was
so powerful, it triggered nuclear test ban sensors thousands of kilometers away.
A just-released analysis of infrasound data shows that the asteroid detonated
with an energy equivalent of about 50 kton of TNT, similar to a small atomic
bomb. This significant impact has received relatively little attention in
Western press. Details are available today on http://spaceweather.com.
SUNSPOT UPDATE: Since it emerged last weekend, new-cycle sunspot 1029 has
become the biggest and most active sunspot of 2009. It is crackling with B- and
C-class solar flares and putting on a good show for amateur astronomers. This
one sunspot does not put an end to solar minimum, but it is a remarkable break
from the calm. Check htttp://spaceweather.com for images and updates.
