What do you think about "arriving" in the following context:
"The subject of this paper and the related research conducted by the authors is a geomagnetic signal component characterizing a variable geomagnetic field. The sources of this field are corpuscular flows of magnetized plasma arriving from the Sun together with the solar wind"
I was in doubt because of the synonym "coming". If you have other suggestions, you are welcome.
Does emanating hit the spot?
