The Sun Online and solar activity. August 21, 2014

We expect continued C-class flaring activity from several active regions on the disc. A new -yet unnumbered- active region has crossed the solar NE limb and might boost solar activity further in the coming days. Quiet geomagnetic conditions are expected in the coming 3 days: there are no high speed wind streams expected from coronal holes, nor are there any new CMEs on the way to the Earth.

Venus and Jupiter at Dawn 

Image Credit & Copyright: Stefano De Rosa

 On Monday morning, Venus and Jupiter gathered close in dawn skies, for some separated by about half the width of a full moon. It was their closest conjunction since 2000, captured here above the eastern horizon before sunrise. The serene and colorful view is from Istia beach near the city of Capoliveri on the island of Elba. Distant lights and rolling hills are along Italy’s Tuscan coast. Of course, the celestial pair soon wandered apart. Brighter Venus headed lower, toward the eastern horizon and the glare of the Sun, while Jupiter continues to rise a little higher now in the sky near dawn. The two brightest planets meet again next June 30th, in the evening twilight above the western horizon.

Messier 106
 (also known as NGC 4258) is a spiral galaxy in the constellation Canes Venatici. It was discovered by Pierre Méchainin 1781. M106 is at a distance of about 22 to 25 million light-years away from Earth. It is also a Seyfert II galaxy. Due to x-rays and unusual emission lines detected, it is suspected that part of the galaxy is falling into a supermassive black hole in the center. NGC 4217 is a possible companion galaxy of Messier 106.
