Visible Light · HMI ContinuumWhat the Sun looks like with sunspotsThe photosphere — the visible "surface" of the Sun. Dark regions are sunspots: cooler magnetic concentrations.

Corona · AIA 193 Å1-million-degree plasmaThe outer atmosphere of the Sun glowing in extreme ultraviolet. Bright loops are magnetic field structures; dark regions are coronal holes — sources of high-speed solar wind.

[05] SOHO LASCO Coronagraphs ESA / NASA · L1 CME WATCH

LASCO C22 to 6 solar radiiInner coronagraph — watches for coronal mass ejections (CMEs) leaving the Sun's atmosphere. The bright disk is an occulter blocking the photosphere.

LASCO C33.7 to 30 solar radiiWide-field coronagraph. Shows CMEs racing into space, plus background stars and occasionally planets passing through view.
