                         mapping total electron contents (TEC) retrieved from the phase 
                         delay of the GNSS radio waves. The data obtained by ground-based 
                         GNSS receiving network RBMC/IBGE, LISN, IGS and RAMSAC were used. 
                         It was possible to monitor spatial and temporal variation of TEC 
                         by twodimensional form with 100 500 km of spatial resolution and 
                         10 minutes time resolution. During the period of December 2013 to 
                         March 2014, periodic spacing plasma depletion forms (bubbles) were 
                         observed along the longitudinal extension with the separation of 
                         800 1000 km. Salient features of the observed plasma bubbles and 
                         the importance to space weather application will be discussed.",
