We describe the preliminary design of a magnetograph and visible-light imager instrument to study the solar dynamo processes through observations of the solar surface magnetic field distribution. The instrument will provide measurements of the vector magnetic field and of the line-of-sight velocity in the solar photosphere.
This paper describes the objectives of the marshall space flight center (msfc) solar ultraviolet magnetograph investigation (sumi) and the optical components that have been developed to meet those.
Solar-b instrument components managed by the marshall space flight center. Back to newscenter home: focal plane package: the focal plane package of the solar optical telescope contains three separate instruments, a high-resolution imager, an imaging vector magnetograph, and a spectropolarimeter.
We compare completely independent vector magnetic field measurements from two very different polarimetric instruments. The marshall space flight center's imaging vector magnetograph is based on a birefringent filter, routinely measuring all four stokes parameters integrated over the filter bandpass (1/8 å) which is tunable across the fe i λ5250 line in 10 må steps.

Filter and polarization analyzer design concepts for the magnetograph are described in detail. The instrument will be tested at jhu/apl, and then moved to the national solar observatory in late 1988.
When we select the reasonable azimuth from them, some errors will appear. The msfc magnetograph obtained the full vector magnetogram of ar noaa10157 at 6:05ut on 23 november, 2003 which is about 19 h before the s 3 t spatially scanned observation.
Projects include or have included the msfc vector magnetograph, the solar ultraviolet magnetograph instrument (sumi), the goes soft x-ray imager, the yohkoh mission, the multi-spectral solar telescope array (mssta), the ulysses mission, the solar and heliospheric observatory mission (soho - esa/nasa), and the global oscillations network group (gong - nsf/national solar observatory).
Detailed knowledge of active region magnetic structures is crucial to understanding many solar phenomena, because the magnetic field both defines the morphology of structures seen in the solar atmosphere and is the apparent energy source for solar flares. The new vector magnetograph was conceived in response to a perceived discrepancy between.
We describe an instrument we have built and installed at mees solar observatory on haleakala, maui, to measure polarization in narrow-band solar images. Observations in zeemansensitive photospheric lines have been made for nearly all solar active regions since the instrument began operations in 1992. The magnetograph includes a 28-cm aperture telescope, a polarization modulator, a tunable.

The msfc vector magnetograph works by measuring the amount of polarization in the light which originates from sunspots at one specific wavelength, 5250.
The difference in value between the vector magnetic fields measured by s 3 t and msfc may be caused by the following: (1) distortion due to solar rotation. The msfc magnetograph obtained the full vector magnetogram of ar noaa10157 in 3 min at 15:53 ut on 21 october, 2003 which is about 12 h later than the s 3 t spatially scanned observation.
