     3No Search Parameters have been defined to describe observer location. 
     4Two classes of description are appropriate, one for ground-based 
     5observations and one for space-based data, particularly ''in situ'' 
     6measurements.  For Earth observatories, a straightforward geographic 
     7latitude / longitude / altitude description should suffice, but it is 
     8not clear how useful this would be as a discriminator for data searches. 
     9For space platforms, where the description of location for ''in situ'' 
     10data is especially important, we defer to the model (to be) adopted 
     11by the VSPO.  It should be noted, though, that as stereoscopic imaging 
     12of the Sun from space observatories becomes more important, search 
     13parameters associated with observer location with respect to solar 
     14coordinate frames may have to be introduced.
