CHANCE OF STORMS: Earth's magnetic field is about to receive a glancing blow from three CMEs observed leaving the Sun between Oct. 20th and 22nd. Forecast models suggest that the three clouds merged en route to Earth, and their combined impact could trigger a mild polar geomagnetic storm on Oct. 24-25. High-latitude sky watchers should be alert for auroras. Aurora alerts: text, voice.

SOLAR FLARE! Solar activity is high. On October 24th at 00:30 UT, Earth-facing sunspot AR1877 erupted, producing a powerful M9-class solar flare. NASA's Solar Dynamics Observatory recorded the blast:

Update #1: The eruption hurled a faint CME into space and it appears to be heading toward Earth. The arrival time is not yet known.

Update #2: NASA's Solar Dynamics Observatory has released a full-disk movie of the explosion. Play it.

Gold Grows On Eucalyptus Trees

Australian researchers confirm that deep-rooted Eucalyptus trees pilfer gold from ore deposits underground and transport them into their leaves.

Leaves preferentially stored microscopic gold particles about eight micrometers wide on average. Study authors speculate the particles came from underground, seemingly taken up by the root system of the trees. About 20 leaves needed to be sampled to statistically reveal the presence of gold underneath the trees.

 

"Gold is probably toxic to plants and is moved to its extremities (such as leaves) or in preferential zones within cells in order to reduce deleterious biochemical reaction," the authors conclude.

Orionid meteor Over Summit County, CO

The Orionid meteor shower takes place in October and November each year, peaking in mid-October. The Orionids are noted for being bright and fragments, according to NASA, with an average speed of about 148,000 mph (238,000 kph).

The Orionids, like all meteor showers, are named after the constellation in which they appear to come from, which in this case is Orion the Hunter. While the constellation is best visible in the Northern Hemisphere, the meteor shower is visible in both the northern and southern hemispheres.

Even with the Moon obscuring the view, NASA's All-Sky Fireball network captured Orionid Meteor Shower's fireballs slam into the Earth's atmosphere. The two seen in this video were captured by several cameras in the United States on Oct. 20, 2013. Read more about it here: http://goo.gl/XwOqLe
