Like many people I was able to get some nice photos of the transit of venus (over 1,400 covering the whole event with a dslr only, no scope/mount).
As we know, viewing the transit with the (protected) naked eye venus made an inverted U shape (for us Aussies) across the sun's disc. If you account for the rotation of the earth/sun and "fix" the sun from apparently rotating then venus tracks straight across the face.
What I've been trying to find out for weeks and failing (even observatories I've contacted are stumped) is what are the scientific names for those two path types? "The curved path" and the "straight path after accounting for rotation" are not very elegant or explanatory. Everything in science seems to be given at least one name and there must be names for these two types of paths that when spoken to someone in the field they know exactly what you refer to. For example "analemma" is an exact term for a type of path the sun make and you only have to speak the word for someone to understand without having to then explain it. I have seen different sites try to use their own terminology to label the two paths but mostly they just don't.
So please put me out of my misery oh wise ones, what are the scientific terms for the two types of transit paths?
Refer to my image of both paths:
