SDO Lunar transit (August 6, 2013)

For almost 1 1/2 hours the Moon made an appearance in NASA's Solar Dynamics Observatory's view on August 6, 2013. The Moon itself looks much bigger than the Sun – as the Moon is many times closer to Earth (and to SDO) than the Sun

Magnetic pole reversal of the Sun 3 – 4 months away

Magnetic pole reversal of the Sun 3 – 4 months away

As it does approximately every 11 years on a solar cycle, the Sun's magnetic field is now reversing. Measurements have confirmed that we are about 3 – 4 months away from complete magnetic field reversal when Sun's inner magnetic dynamo will re-organize itself.

SOHO observes an amazing solar eclipse of Jupiter on June 19, 2013

On June 19, 2013 NASA`s SOHO coronagraphs observed an eclipse of Jupiter by the Sun, as the planet got directly behind the solar disk; being totally obscured. This event is a rare Jupiter solar conjunction, that happens only twice within Jupiter`s 12-year orbit around
