Yeah.. we will be facing the more active side of the sun for the next few days. Which probably isnt good since this side has shot off a few large CMEs and a couple flares last week. Also, the sun is due for a pole flip.

Surely you mean a polar flip...............

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. 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.

A diamond-studded black pebble from Egypt is reportedly the first-ever evidence of a comet striking Earth.

A team of scientists analyzing the rock, which was discovered by a geologist in the Egyptian desert a few years ago, concluded that is the first known nucleus of a comet rather than material from a meteorite.

“Comets always visit our skies - they’re these dirty snowballs of ice mixed with dust - but never before in history has material from a comet ever been found on Earth,” David Block, a professor at Wits University in Johannesburg, said in a release.

About 28 million years ago, the comet struck Earth’s atmosphere and exploded, unleashing a shock wave of fire and heating up the sand beneath it to about 2,000 degrees Celsius, according to the release. The hot sand created a scattering of yellow silica glass over an area of nearly 4,000 miles.

The impact also produced diamonds, which normally form from carbon in areas of very high temperatures and pressures but can also form from shock, explaining the bits of diamond on the comet nucleus. The researchers named the rock Hypatia to honor the first well-known female mathematician, astronomer and philosopher, Hypatia of Alexandria.

Tucson, Ariz. -- Scientists are unraveling more information on Comet C/2012 S1 (ISON) as it continues on its journey toward the Sun. Comet C/ISON will skim 730,000 miles above the Sun’s surface on Nov. 28 and has the potential to be readily visible from Earth starting in early December.

“We measured the rotational pole of the nucleus. The pole indicates that only one side of the comet is being heated by the Sun on its way in until approximately one week before it reaches it closest point to the Sun,” said Planetary Science Institute Research Scientist Jian-Yang Li, who led a team that imaged the comet.

“Since the surface on the dark side of the comet should still retain a large fraction of very volatile materials, the sudden exposure to the strong sunlight when it gets closer to the Sun than Mercury could trigger huge outbursts of material,” Li said.
