Round about Soho

Round about Theta. Part I Prehistory

The next steps after this prehistoric Part I will be directed to a description of the Howe operators introduced by Kudla and Millson and their special Schwartz forms and classes. This has as attractor the fact that the modular and automorphic forms arising naturally in context with these classes find very nice geometric interpretations of their Fourier coefficients and thus lead to an intriguin...

SOHO Security: A Technical Briefing

Small businesses and home offices (SOHO) are increasingly connected to the Internet through broadband networking (cable, DSL, wireless) twenty-four hours a day, seven days a week (24/7). Of course, neither small businesses, nor individuals working in their home offices, have the financial resources, or the technical expertise, to protect themselves as effectively as organizations with well-staf...

The Radiometric Calibration of SOHO

Euv Sunspot Plumes Observed with Soho

Bright EUV sunspot plumes have been observed in five out of nine sunspot regions with the Coronal Diagnostic Spectrometer – CDS on SOHO. In the other four regions the brightest line emissions may appear inside the sunspot but are mainly concentrated in small regions outside the sunspot areas. These results are in contrast to those obtained during the Solar Maximum Mission, but are compatible wi...
