Four types of request may be made by a GO, GTO, CS, or PC. ... The first type is a HOPR (HST Operations Problem Report), which describes an operational problem that occurred in obtaining data and which requests a repetition of the lost observation. ...

... Files in red?history) . ... Solar Wind . ... In sunspot regions field lines form arches which hold back the solar wind, but in the "holes" in between they extend outwards and allow the plasma to accelerate unimpeded. ... It was therefore expected that the solar wind above the Sun's poles would be relatively fast and smooth-flowing. ... All planetary orbits lie approximately in the same flat plane as that of the Earth ("plane of the ecliptic"), which is also close to the Sun's equatorial plane. ...

Not everyone accepted Parker's theory of the solar wind when it was first published in 1958, and it was debated until observations confirmed it. ... Lower-velocity solar wind comes from regions in between sunspot regions and coronal holes . ... It was therefore expected that the solar wind above the Sun's poles would be relatively fast and smooth-flowing. ...

... The Si VIII line width measurements and N e estimates based on SUMER observations are combined with LASCO and UVCS output to provide an overview of its variations with height above a polar coronal hole. ... Combining the Si VIII half width at 1/e of the peak intensity with the UVCS O VI half width, we find a small increase of the half width from 1 to 1.2 , then a plateau until 1.5 , thereafter a sharp increase until 2 , finally a more gradual increase reaching 550 km s -1 at 3.5 . ...

... December 21, 1997 . ... Advantages are briefly discussed of gaining in spectral resolution, which is accompanied by losses in signal level, as compared with the attempts to improve the accuracy of measurement of line parameters by means of rising the S/N ratio alone with increasing the exposure time. To partially solve the problem of observations of faint objects at the BTA a new design echelle spectrometer is proposed. high resolution spectroscopy . ...
