Match the Solar feature to its description. (Select P-Photosphere, C-Chromosphere, O-cOrona, W-solar Wind, F-Flares, T- sunspoTs. If the first is P and the rest C, enterPCCCCC). A) dark regions associated with the Sun's magnetic fieldB) flow of particles from the SunC) bright visible surface of the SunD) hot, rarefied gas surrounding the SunE) place where the majority of absorption lines formF) burst of energy that shows up as a sudden brightening of the Sun
The figure below shows measurements of the solar wind magnetic field at 1 AU over a 24 hour period. Themeasurements are in GSM coordinates and include the vector components of the field as well as the correspondingangles (θ is the polar angle, which correspond to Bz, and φ is the azimuthal angle). Based on the figure, briefly describewhat event occurred between 13 and 14 UT.
explain in your own words solar flares.
( I will add it to my homework don't be short too, thank you :) )
