XRT's flare patrol captured an
X1.3 flare from Active Region
12046 on April 25th at 00:17 UT.
The movie shows the eruption taking place in the
SDO/AIA 131 Angstrom wavelength channel.
Plasma in the Sun's atmosphere increases in brightness as the underlying magnetic loops rise.
This increase in brightness is due to plasma bunching up around the expanding loops.
The surrounding environment has a temperature of about 1 million Kelvin, which allows
XRT to see the same structure with its thick aluminum and medium beryllium filters. The
interesting dynamics of this flare might lend support to the
'break-out model' of solar
flare eruptions.
