SUMMARY:Flares: highly energetic explosions on the Sun 
DESCRIPTION:Flares: highly energetic explosions on the Sun \nDr. Alberto Sa
 inz-Dalda\n\nFlares are among the most energetic magnetic solar phenomena.
   They are often accompanied by ejections of charged particles, which have
   a direct influence on the Earth in terms of Aurora or radio and satellit
 e outages. The sudden nature of flares - some of them only last minutes - 
 makes them an  elusive feature when observed from ground-based telescopes.
  These measurements  are especially challenging when we focus on magnetic 
 fields and velocities in the  different solar layers where flares develop 
 and occur. I will present flare observations taken with different instrume
 nts, each targeting  different observables, and I will show what we can le
 arn from ground-based polarization  measurements.
