\""Sweeping<\/a>

“Sweeping Arches and Loops”, solar magnetic activity viewed in the ultraviolet, June 30, 2014.<\/p><\/div>\n

Looking at some of the photos returned by NASA’s Solar Dynamics Observatory (SDO), you’d think contemporary solar observing\u00a0had\u00a0little in common with what was\u00a0being done at Kodaikanal c. 1900-1910. But in addition to the dramatic\u00a0images of solar loops like the one shown above, SDO also sends\u00a0back sunspot records\u00a0that closely resemble the photos and charts produced by C. Michie Smith, John Evershed, and company.<\/p>\n

According to SDO\/NASA:<\/p>\n

“The Sun sported a whole slew of substantial sunspots over the past 11 days (July 1-10, 2014). This movie and still show the Sun in filtered white light speckled with more and larger sunspots than we have seen in quite some time. Sunspots are darker, cooler regions on the Sun created by intense magnetic fields poking through the surface. The Sun may have passed its peak level of activity, but it will still be producing many more sunspots and solar storms during the rest of this solar cycle. The still image was taken on July 8 at 22:24 UT.”<\/p>\n

Looks familiar!<\/p>\n
