This rapidly growing sunspot only starting forming less than a day ago and it is already 5 times the size of planet Earth. X-class flares? Also, Check out this coronal hole!

…Sunspots are islands of magnetism that float on the surface of the sun. This one is emerging from depth and changing at such a rapid pace that its magnetic field is likely unstable. A reconnection event in AR1678’s magnetic canopy could lead to a significant solar flare. Stay tuned!

Sunspots AR1619 & AR1618

The sun is super active! Seems like the earth is too! Lots of activity! Check out these sunspots growing ever so larger.

This channel is especially good at showing areas where cooler dense plumes of plasma (filaments and prominences) are located above the visible surface of the Sun. Many of these features either can’t be seen or appear as dark lines in the other channels. The bright areas show places where the plasma has a high density.

AR1515 M- Class Solar Flare

Big sunspot AR1515 erupted on July 2nd at 10:52 UT, producing an M5.6-class solar flare that almost crossed the threshold into X-territory. NASA’s Solar Dynamics Observatory recorded the extreme ultraviolet flash: SDO movie

A pulse of x-rays and UV radiation from the flare illuminated Earth’s upper atmosphere, producing waves of ionization over Europe. Such waves alter the propagation of low-frequency radio transmissions. In Lofoten, Norway, Rob Stammes recorded the ionospheric disturbance using a 60 kHz receiver.

The eruption also hurled a CME into space, but not directly toward Earth. The south-traveling cloud could deliver a glancing blow to our planet’s magnetosphere on July 4th or 5th. Stay tuned for updates.

Happy Summer!!!

Happy Summer! Around 7pm EST the earth will tilt on its axis at an angle closest facing the sun! Perfect heat wave to welcome the summer of 2012.

The summer solstice occurs exactly when the axial tilt of a planet’s semi-axis in a given hemisphere is most inclined towards the star that it orbits. Earth’s maximum axial tilt to our star, the Sun, during a solstice is 23° 26′. This happens twice each year, at which times the Sun reaches its highest position in the sky as seen from the North or South Pole respectively.
