X-class flare this morning

An X-class flare occurred in Active Region 11429 this morning at about 0400 UTC (or last night at 11:00 pm ET). Here is the EVE spaceweather feed showing the Sun brightening. Stayed tuned for more images!

Here is a picture of the X1.1 flare at 04:00:32 UT today. You can clearly see the two ribbons that form along the flare. This image is in light at a wavelength of 1700 Å, in the ultraviolet. It measures the response of the chromosphere rather the corona seen in the shorter wavelength channels.
