Details in my link above.

Telemetry from the spacecraft and rocket showed a flawless beginning for the mission to study the sun in detail.

The Atlas V roared to life Thursday morning to send the Solar Dynamics Observatory into space on its mission to evaluate the complex mechanisms of the sun. Liftoff came on-time at 10:23 a.m. EST from Launch Complex 41 at Cape Canaveral Air Force Station on Florida's Atlantic Coast.

The SDO spacecraft is in good shape midway through the launch phase that will eventually place it in an elongated orbit reaching more than 21,000 miles high. Eventually, SDO's orbit will be circularized and will reach about 22,300 miles in [snip] geosynchronous orbit.
