~ Space Weather Update~ M-CLASS SOLAR FLARE, CME Impact~ More Coming

M-CLASS SOLAR FLARE: Solar activity is picking up. New sunspot AR1865 erupted this morning (Oct. 9th at 01:48 UT), producing the strongest solar flare in nearly two months. NASA's Solar Dynamics Observatory recorded the M2.8-class eruption: movie. Earth was not in the line of fire, but future eruptions could be geoeffective as the sunspot turns toward our planet in the days ahead. Solar flare alerts: text, voice.

CME IMPACT, GEOMAGNETIC STORM: An interplanetary shock wave, possibly the leading edge of a CME, hit Earth's magnetic field on October 8th at approximately 2015 UT (1:15 pm PDT). The impact sparked a G1-class geomagnetic storm (in progress) and bright auroras around the Arctic Circle. Lana Rupp photographed this "stunning display of color" over Borgarnes, Iceland, during the early hours of Oct. 9th:

Earth Shift: Underwater Landslides Taking Place*

While the crisis above ground seems to be multiplying, our Earth has its own agenda, or is it the same agenda?

To say it’s an awesome feeling to witness lands suddenly disappear in the vicinity in which one lives is an understatement, but what if the land is sliding under the sea. One feels well it doesn’t affect me or does it?

Experts can give us a clue, but one thing is sure, we cannot take nature for granted!

67 underwater landslides found off the Maltese Islands

 

A high concentration of submarine landslides have been documented from an area of 370 square km of seafloor in the north-east of Marsaxlokk. The discovery was made using advanced seafloor exploration techniques and was reported in a study led by Dr Aaron Micallef, a marine geologist at the Department of Physics, University of Malta.

~ Space Weather Update~ CME IMPACT EXPECTED

CME IMPACT EXPECTED: A minor CME, propelled towarded Earth by a magnetic filament erupting on the sun, could strike our planet's magnetic field during the late hours of Oct. 9th. NOAA forecasters working through the US government shutdown estimate a 30% to 40% chance of polar geomagnetic storms. Aurora alerts: text, voice.

JUNO SPACECRAFT TO FLY BY EARTH: NASA's Juno spacecraft will slingshot past Earth on October 9th for a velocity boost en route to Jupiter. At closest approach the spacecraft will be only 347 miles above Earth's surface. This map shows the spacecraft's ground track:

During the flyby, Juno's science instruments will be activated to sample the Earth environment--a practice run for data-taking when the spacecraft reaches Jupiter in 2016. Despite the shutdown of the US government, "the flyby will continue as planned," says Juno principal investigator Scott Bolton of the Southwest Research Institute. "The commands associated with our instruments were already on board before the shutdown."

www.eyesonthesky.com There are a number of fantastic open clusters in Perseus; one is easy (and best!) with binoculars; the other can be seen with binoculars, but is better in a wide field telescopic view. This week, check out the Alpha Persei Cluster and the Double Cluster in the "hero" constellation, and even learn a bit about the mythological background of Perseus too. See what's up in the night sky every week with "Eyes on the Sky" videos, astronomy made easy.

Legendary Draconid meteors best after sunset October 7

Moon and evening planets on October 7

Before nightfall on October 7 and 8, as you’re preparing to watch for meteors, look southwest to see the waning crescent moon between the planets Venus and Saturn.

The constellation Draco the Dragon will be spitting out meteors, also known as shooting stars. The Draconid shower is predicted to produce the greatest number of meteors on the night of October 7, but the next night might be good, too. Watch for them first thing at nightfall. Fortunately, the thin waxing crescent moon won’t interfere with this year’s Draconid meteor display. In fact, the moon and planets set in the southwestern sky around nightfall, serving as a wonderful prelude to tonight’s Draconid meteor show
