Karl Battams, one of the STEREO team members confirmed the successful test roll of the spacecraft to 135 degrees. Carl noted that the angle of roll is chosen very well. From 1 to August 5, the comet will be visible in the instrument HI-2B, then observations will be continue with HI-1B camera. The first data will be transmitted to Earth on August 2-3 and will be available from August 4.
The comet may be a very bright and one of the main objectives of the observations will be study the effect of forward scattering. This effect can increase the brightness of comet by several magnitudes and we will see this effect from SOHO spacecraft, in late September.
