THE ILLUMINATION AND GROWTH OF CRL 2688: AN ANALYSIS OF NEW AND ARCHIVAL HUBBLE SPACE TELESCOPE OBSERVATIONS

We present four-color images of CRL 2688 obtained in 2009 using the Wide-Field Camera 3 on Hubble Space Telescope. The F606W image is compared with archival images in very similar filters to monitor the proper motions of nebular structure. We find that the bright N-S lobes have expanded uniformly by...
