! Proposal 6878, submission 1 ! PI: JEFFERYS, WILLIAM ! Received Thu Feb 29 11:40:58 EST 1996 ! From: alw@clyde.as.utexas.edu Proposal_Information Title: Parallax of NGC 6853 Proposal_Category: GTO/AST Scientific_Category: STELLAR POPULATIONS Cycle: 6 Investigators PI_name: Art Whipple PI_Institution: UNIVERSITY OF TEXAS CoI_Name: Fritz Benedict CoI_Institution: UNIVERSITY OF TEXAS Contact: y Questions Observing_Description: Observe NGC 6853 and associated reference frame at maximum parallax factor during Cycle 6. Schedule two orbits in October- November 1996 and two orbits in April-May 1997. Real_Time_Justification: Calibration_Justification: Will require continued LTSTAB and OFAD observations. Additional_Comments: Abstract: NGC 6853 is one of the closest planetary nebulae. Its trigonometric parallax is presently poorly known. HST observations have the potential to reduce the parallax uncertainty to about 0.0005 arcsec.
