The next launch of our EVE calibration payload is on NASA sounding rocket 36.275 planned for February 23, 2011 from the White Sands Missile Range (WSMR). This flight will provide the second underflight calibration for the SDO EUV Variability Experiment (EVE) instrument. The first calibration rocket flew on May 3, 2010 (NASA 36.258, the Black Brant rocket is shown "on the rail" at left).

The launch window is from 11:20-11:50 MST. This is near local noon to minimize the atmospheric absorption of the solar EUV radiation observed during the rocket flight. Unlike the TIMED rockets, where SEE had to also be turned on, EVE is all all the time.

Due to security regulations, we cannot provide realtime coverage of the launch.
