OBSID 08242, HD 245770 2006:300:07:08, ACIS-I NONE - Combining X-ray Scattering with Extinction, Absorption, and Emission: Multiwavelength Constraints for Dust Grain Models. RADIATION SUMMARY ----------------- Solar soft proton flux is very low (http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity: At midnight the visible solar disk was spotless. The solar flare activity level was very low. No C class events were recorded yesterday. (http://www.dxlc.com/solar/). GOES x-ray flux: Falling off the bottom of the scale!. CMEs reported for past two days: October 24-26: No obvious partly or fully Earth directed CMEs were detected in LASCO imagery.

First, the Space Shuttle Columbia delivered it to a low Earth orbit. Then, the Inertial Upper Stage rocket boosted Chandra up to an altitude where a built-in propulsion system took Chandra to its elliptical orbit. The orbit evolves in time.
