Solar Field Polarity Reversal Like the magnetic field poles of the earth the sun's magnetic field also experiences a complete magnetic polar reversal. However, unlike the earth's magnetic field which experiences geomagnetic reversal every several million years and sometimes every 400 thousands years, the solar magnetic field polarity reversal occurs in shorter intervals of … [Read more...] about Solar Polarity Reversal in Progress

Coronal Holes
Coronal holes are areas in the sun's corona that cooler; therefore darker, and from where a large portion of high speed the solar wind comes from. Coronal holes were first discovered when X-ray space telescopes on board the Skylab were first flown above the earth's atmosphere. Coronal holes are also detected where open or uni-polar solar magnetic field lines are present or … [Read more...] about Coronal Holes
SDO Solar Images & Data Collection 2010-2013
NASA's Solar Dynamics Observatory (SDO) 30 days videos, compare the sun's activity from periods of t 2.5 years, showing increased solar activity. Images shown were collected in 171 Angstrom wavelength of extreme ultraviolet light. Areas of intense activity is shown as the brighter areas with electromagnetic field loops above those areas. This activity should increase … [Read more...] about SDO Solar Images & Data Collection 2010-2013
