Abstract: Edge localized modes (ELMs), edge turbulence and other fluctuations in the edge region of NSTX plasma are observed by fast cameras. ELMs categorized as Type I, III, and V are found in NSTX and other MARFE-like activity is seen near the center stack in double null plasmas. Edge turbulence filaments are almost always found in NSTX. An interpretation of ELM images, which shows a complex ELMs structure, is presented
