The Sun Online and solar activity. June 2, 2014

Six sunspot regions are visible at the front side of the solar disk. The background level of the X-ray flux measured by GOES is at B-class level. No solar flares were observed during the past 24 hours. LASCO/C2 observed at 8:36 UT a CME, which is associated with a backsided event. No Earth-directed CMEs were detected.  C-class flares are expected for the next 48 hours, with NOAA ARs 2077 and 2079 as strongest source candidates. We are currently experiencing slow solar wind conditions, with a speed between 260
and 300 km/s. The magnitude of the interplanetary magnetic field is stable near 5 nT, with a fluctuating Bz component between -5 and +5 nT. The  geomagnetic conditions were quiet. A small coronal hole that passed the central meridian on 29 May can still influence the geomagnetic field within the next 24 hours.
Geomagnetic conditions are expected to remain quiet, though locally a brief active episode is possible.

The Space Station Captures a Dragon Capsule

The space station has caught a dragon. Specifically, in mid-April, the International Space Station captured the unmanned SpaceX Dragon capsule sent to resupply the orbiting outpost. Pictured above, the station’s Canadarm2 had just grabbed the commercial spaceship. The Dragon capsule was filled with over 5000 lbs (2260 kilos) of supplies and experiments to be used by the current band of six ISS astronauts that compose Expedition 39, as well as the six astronauts that compose Expedition 40. After docking with the ISS, the Dragon capsule was unloaded and eventually released, splashing down> in the Pacific Ocean on May 18. The current Expedition 40 crew, now complete, will apply themselves to many tasks including the deployment of the Napor-mini RSA experiment which will use phased array radar and a small optical telescope to monitor possible emergency situations on the Earth below.

Andromeda Galaxy

The Andromeda Galaxy is approaching the Milky Way at about 110 kilometres per second (68 mi/s). We measure it approaching relative to our sun at around 300 kilometres per second (190 mi/s) as the sun orbits around the center of our galaxy at a speed of approximately 225 kilometres per second (140 mi/s). This makes Andromeda one of the few blueshifted galaxies that we observe. Andromeda’s tangential or side-ways velocity with respect to the Milky Way is relatively much smaller than the approaching velocity and therefore we expect it to directly collide with the Milky Way in about 4 billion years. A likely outcome of the collision is that the galaxies will merge to form a giant elliptical galaxy.  Such events are frequent among the galaxies in galaxy groups. The fate of the Earth and the Solar System in the event of a collision is currently unknown. Before the galaxies merge, there is a small chance that the Solar System could be ejected from the Milky Way or join M31.
