Timelapses of Solar Puffing Are Gently Mesmerizing

When a trio of telescopes teamed up to stare at the sun, they captured the dynamics of solar puffing. The timelapse of a puff is gently mesmerizing: not outright stunning or mind-boggling, but somehow still incredible in their understated hiccupping release of plasma.

SOHO, STEREO and the Solar Dynamics Observatory (SDO) captured images of the sun from different angles on January 17-20, 2014.

"Solar puffing" is a fantastic descriptive phrase that I hope makes it into the technical lexicon. The puffs started happening about once every three hours, building into a much larger eruption after twelve hours of puffing. That the series of energetic jets and flares was recorded in advance of a larger corneal eruption suggests that the smaller puffs may smooth the way for larger eruptions.

The timelapses aren't spectacular β€” I was hoping for a pursed-lipped puff like the mushrooms in Plants vs. Zombies, no matter how scientifically ridiculous that is β€” yet somehow the slow, gentle puff of bright corneal material is enough to keep me watching through each jittery loop.

The three perspectives of each telescope observing from a different position allowed researchers to build a three-dimensional model of the puffs, analyzing the mechanics of what happens when our sun starts huffing.


This isn't the first time multiple telescopes were used to view the same event. On March 29th, a solar flare was caught by five observatories, producing an astonishingly detailed look at the phenomena.

Gorgeous GIF Captures the Sun Puffing Plasma

Last year, a trio of sun-gazers β€” SOHO, STEREO and Solar Dynamics Observatory (SDO) β€” captured unusual eruptions of plasma being "puffed" from the sun's corona. The GIF comes from SDO and shows the jets that caused the puffs.

The three colors in the above image β€” red, green and blue β€” corresponded to three coronal temperature regimes, ranging from ~0.8Mk to 2MK.


Today, Nathalia Alzate presented on the event, which lasted three days starting on January 17, 2013, at the National Astronomy Meeting 2014 in Portsmouth. Explained Alzate:

Looking at the corona in Extreme UltraViolet light we see the source of the puffs is a series of energetic jets and related flares. The jets are localized, catastrophic releases of energy that spew material out from the Sun into space. These rapid changes in the magnetic field cause flares, which release a huge amount of energy in a very short time in the form of super-heated plasma, high-energy radiation and radio bursts. The big, slow structure is reluctant to erupt, and does not begin to smoothly propagate outwards until several jets have occurred.
