Extended time series of Solar Activity Indices (ESAI) is database including observational, synthetic and simulated sets to study Solar magnetic field variations and their influence on the Earth. ESAI extend the ordinary lengths of some traditional indices of solar activity: sunspot areas, Wolf numbers (equatorial component of magnetic field of the Sun), polar faculae numbers (polar component), mean latitudes, N-S asymmetry of hemispheres (location of activity). Series . ...

Solar High Resolution Studies . ... Dynamic magnetic fields continuously emerging from the solar interior on a wide range of scales, and their interaction with convectively-driven plasma flows, play a major role in shaping the whole solar atmosphere. Even though the fundamental spatial scales of turbulence and magnetic fields are still unreachable with present-day telescopes, polarimetric observations at the highest possible resolution will allow important insights into these issues. ...

... 2003 December 17 . A Proton Aurora . Credit: IMAGE Satellite , NASA . ... Triggered by solar activity, normal auroras are caused by collisions between fast-moving electrons and the oxygen and nitrogen in Earth's upper atmosphere. ... Such a proton aurora is seen above, recorded by the IMAGE satellite . ... Most solar wind protons never reach the Earth to cause auroras because they are completely deflected away at a great distance by the Earth's magnetic field . ... About APOD | ...

... To determine a lower limit to the sensitivity of current observations to measurements of NS surface temperatures, we have used data from the Einstein Slew Survey (Elvis et al. 1990) to establish temperature limits for 275 pulsars which received nonzero exposure during the survey. ... Filled squares correspond to pulsars actually detected in the survey data; the smaller symbols correspond to upper limits to the count rates. ...

. A number of NASA instruments captured detailed images of this coronal mass ejection (CME) on August 31, 2012. Although CMEs can damage sensitive technological systems, this one just struck a glancing blow to Earth's atmosphere. New research has identified quasi-annual variations in solar activity, which may help experts better forecast CMEs and potentially damaging space weathers. NASA Goddard Space Flight Center
