Live Solar and Aurora Images

The Sun and the aurora as they look right now, in many wavelengths, from NASA and NOAA satellites. Images refresh automatically while the page is open.

The Sun in many wavelengths (NASA SDO)

AIA 193 Å: current image — **AIA 193 Å**
Corona and hot flare plasma. Coronal holes appear dark: the source of fast solar wind streams.

AIA 304 Å: current image — **AIA 304 Å**
Chromosphere and transition region. Shows prominences and filaments at the limb.

AIA 171 Å: current image — **AIA 171 Å**
Quiet corona and coronal loops tracing the magnetic field.

AIA 211 Å: current image — **AIA 211 Å**
Hot active-region corona.

AIA 131 Å: current image — **AIA 131 Å**
Flaring regions: the hottest plasma, bright during flares.

AIA 335 Å: current image — **AIA 335 Å**
Active region corona.

AIA 94 Å: current image — **AIA 94 Å**
Very hot flare plasma.

AIA 1600 Å: current image — **AIA 1600 Å**
Upper photosphere and transition region.

HMI magnetogram: current image — **HMI magnetogram**
Magnetic polarity on the visible surface: complex regions are flare-prone.

HMI continuum: current image — **HMI continuum**
Visible light: sunspots as dark patches.

Solar corona and CMEs (SOHO LASCO)

LASCO C2: current image — **LASCO C2**
Inner corona. Expanding bright clouds are coronal mass ejections.

LASCO C3: current image — **LASCO C3**
Outer corona out to about 30 solar radii.

NOAA SUVI and the aurora ovals

GOES SUVI 304 Å: current image — **GOES SUVI 304 Å**
NOAA operational view of the Sun at 304 Å.

Aurora oval, north: current image — **Aurora oval, north**
OVATION model forecast of the northern auroral oval.

Aurora oval, south: current image — **Aurora oval, south**
OVATION model forecast of the southern auroral oval.

What to look for

Coronal holes (dark regions in 193 Å) release fast solar wind that can raise the Kp index two to four days after they face Earth. Active regions with complex magnetic fields (see the HMI magnetogram) are the likely source of flares: check the X-ray flux when you see them. Coronal mass ejections in LASCO images that expand all around the Sun are directed at or away from Earth and can drive a geomagnetic storm.
