SUMMARY:The basal flux and the solar cycle variations
DESCRIPTION:The basal flux and the solar cycle variations\nDr. Reza Rezaei\
 n\nIn the first part of the talk, I discuss the chromospheric activity of 
  quiet Sun. The so-called basal flux, the minimum chromospheric emission  
 of main sequence stars, is discussed in terms of magnetic and  non-magneti
 c heatings. The second half of the talk is about variability  of the solar
  cycle. The extended minimum of the last cycle caused  speculations about 
 a possible long-term decline in the solar activity.  Based on our observat
 ions in past 15 years, I argue that the Sun does  not cease to generate su
 nspots in the next cycle. Finally I outline new  tools to evaluate chromos
 pheric activities.
