Passage:
On September 1, 1859, English astronomer Richard Carrington recorded a sudden, intense flash of white light while projecting an image of sunspots onto a glass screen. Unaware that amateur observer Richard Hodgson was simultaneously witnessing the identical phenomenon from a separate observatory, Carrington initially suspected that light had leaked through a crack in his telescope's blind. Although Carrington refrained from asserting a definitive causal relationship between the solar eruption and the extraordinary geomagnetic disturbance that blanketed Earth eighteen hours later, he documented that magnetometers at the Kew Observatory registered severe magnetic fluctuations at the precise moment of the optical flare. Furthermore, Carrington emphasized that the solar phenomenon did not alter the shape or dimensions of the sunspot cluster he had been sketching prior to the outburst, nor did it leave any permanent mark on the solar surface after dissipating fifteen minutes later.
Consider each of the choices separately and select all that apply.
