COND. IN LY ALPHA CLOUDS: CYCLE 5 OBSERVATIONS Proposal_Category: GTO/HRS Scientific_Category: !QUASARS & AGN,QUASAR ABSORPTION QSO ABSORPTION LINES Cycle: 5 Investigators PI_name: RAY WEYMANN PI_Institution: OCIW CoI_Name: SIMON MORRIS CoI_Institution: DAO Contact: Y Abstract: Spectra of the QSO pair Q0107-025 A and B will be obtained with the GHRS G140L between 1215 and 1500A. The pair will be used to search for any absorption systems which may or may not be in common with the two, thus setting limits on the linear size of the clouds. Additional spectra in cycle 5 will be used to cover wavelengths greater than 1500A. Questions Observing_Description: We will obtain further GHRS spectra of a close pair of QSOs to study common Lyman alpha absorption systems. Real_Time_Justification: The targets are very faint, and it is neccessary to have minimum GHRS background count rate, therefore we require exposures only for geomagnetic latitude +/- 25 degrees and avoiding the SAA. Contact T. Ake (hrsake@hrs.gsfc.nasa.gov) for details. We will require the Reuse Target Offset capability for Visits 2, 3, and 4. Calibration_Justification: WAVE exposures will be taken as we wish to accurately measure velocity offsets between common absorption features.
