Solar Dynamics Observatory

(SDO) A solar exploration mission planned for launch by NASA in 2007 and the first mission in the agency's Living with a Star (LWS) Program. Set to carry out studies of the Sun's atmosphere in several wavelengths at the same time, SDO will seek to investigate the various transient changes caused by variations in the Sun's magnetic field and thereby help advance our understanding of such phenomena as solar flares, coronal mass ejections, alterations in the solar wind, and other bursts of energy connected with solar activity. These phenomena produce a set of effects described as ‘space weather’, which have a profound influence on the Earth; they not only produce such events as the aurora, but also cause immediate and long-term harm to electrical and communications equipment in groundbased systems, aircraft, and spacecraft. Unpredictable changes in solar radiation or energy output are potential hazards for astronauts working in the unprotected environment of space. SDO is also designed to study magnetic field variations in the Sun's interior, active regions and sunspots and how they develop, and the mechanisms that drive the 11-year solar cycle. Initially, its mission is set to last five years, with the possibility of an extension for a further five years.

such pointing concept has been successfully implemented in europe in the special case of small laser communication terminals with artemis silex and edrs lct but also more recently in us within the optical instruments of sdo (solar dynamics observatory) and goes-r (geostationary operational environmental satellite-r series).
Scientists analyzed data collected from 2010-2016 by the Heliospheric and Magnetic Imager (HMI) instrument on board NASA's Solar Dynamics Observatory. The study required high-precision observations of the Sun over many months.
It's never a good idea for humans to look directly at the sun with their eyes unprotected, but NASA's Solar Dynamics Observatory has the retinal remedy.
