Arecibo as an HI telescope in the coming era of active SKA survey- optimized pathfinders (ASKAP, MSKAP) to be followed by the SKA whence Arecibo? The mid-range SKA is a 0.3-3 GHz+ facility This exactly matches Arecibo, so Arecibo’s science is SKA precursor science 11 September 2008 NSF

VLBI and Arecibo The impact of Arecibo’s sensitivity Arecibo added to the VLBA => 4.5 times better sensitivity (Day & Momjian 2005). 11 September 2008 NSF

VLBI Highlights Post-Painting MK5A Disk-recorded: Three successful Mk5A disk-based runs using L, C and X-band, with HAS, EVN & Global network. These represent; (1) a study of the Zeeman effect for compact components in ULIRGs, (2) jet and counter-jet emission in the giant radio galaxy, NGC315 and, (3) measuring the expansion velocity of SN2008D associated with the transient X-ray source in NGC2770 (Target of Opportunity).
