Space Weather News for July 8, 2000

Coronagraphs on board the orbiting ESA/NASA Solar and Heliospheric Observatory (SOHO) recorded a full halo coronal mass ejection (CME) on July 7th. Forecasters estimate that material from the CME will arrive in the neighborhood of Earth on July 11th.

While the CME was ongoing, SOHO's wide field coronagraph also captured the planet Mercury racing by the Sun twice as fast as the drifting field of background stars. Mercury joined two other planets, Mars and Venus, in the coronagraph's field of view.

Amateur astronomers are discovering pieces of a giant comet that broke apart in antiquity as the fragments zoom perilously close to the Sun. You can join the hunt, too. All you need is a computer and an internet connection to view realtime data from the orbiting ESA/NASA Solar and Heliospheric Observatory.

Comet 1999 LINEAR S4, which can already be seen through binoculars, is expected to become a faint naked-eye object similar in appearance to the Andromeda Nebula as it glides by the Big Dipper this month. Maximum brightness is expected on July 23, 2000.

Solar activity was low over the weekend and is expected to remain so for the next 24 to 48 hours. Nevertheless, on July 1st and 2nd coronagraphs on the Solar and Heliospheric Observatory captured a beautiful sequence of images showing Mars as it passed less than one degree from the Sun. The animation includes several coronal mass ejections associated with small solar flares.

On a planet that's colder than Antarctica and where water boils at ten degrees above freezing, how could liquid water ever exist? Scientists say a dash of salt might help.
