We are constructing a spectro-­polarimeter using the 40-­cm coronagraph at the Evans Solar Facility of the National Solar Observatory in Sunspot, NM for the purpose of measuring the vector magnetic field in prominences and filaments. The Prominence Magnetometer (ProMag) is comprised of a polarization modulation package and a spectrograph. The modulation optics are located at the prime focus of the coronagraph along with calibration optics and a beamsplitter that creates two beams of orthogonal Stokes states. The spectrograph resides at the coude focus of the coronagraph. The polarizations of the two chromospheric lines of neutral helium, at 587.6 nm and 1083.0 nm, are to be observed simultaneously. We present details of the design of the spectro-­polarimeter.

In this paper we will make a comparative study of velocities as they result from processing the images of a specific active region observed by two satellites: SOHO and STEREO A. The purpose of this study is the detection of micro-CMEs... more

In this paper we will make a comparative study of velocities as they result from processing the images of a specific active region observed by two satellites: SOHO and STEREO A. The purpose of this study is the detection of micro-CMEs (Coronal Mass Ejections). The observed active region is accompanied by a complex filament (in chromosphere) and a sunspot pore (in photosphere) and it was registered by the Catania Observatory as AR 05, AxX.

A complex filament composed by a main body a polar filament and a tail—a small filament situated between active regions, was observed between 6 and 14 January 2001. A decaying active region plays the role of attractor for this filament.... more

A complex filament composed by a main body a polar filament and a tail—a small filament situated between active regions, was observed between 6 and 14 January 2001. A decaying active region plays the role of attractor for this filament. We have studied the dynamics of the filament which disappeared in a spectacular CME, produced after a helical up-awarded movement of plasma in the filaments loops.
