... Over the last decade the uninterrupted, high-resolution coverage of the Sun both from the excellent range of telescopes aboard many spacecraft and from ground-based instruments has led to a wealth of observations of small-scale dynamic events observed from the chromosphere to the transition region and corona. ... SoHO observations have further characterized many transient features, such as bi-directional jets, blinkers, coronal jets, and bright points. ...

. Better satellite instruments are improving measurements of solar energy reaching Earth. Exactly determining the contribution of solar fluctuations to rising global temperature is expected to become possible as new instruments, such as the Total Irradiance Monitor above, further refine solar measurements. The device is scheduled to launch next month on NASA's Glory spacecraft. NASA
