| Popis: | We conducted a series of multi-filtered imaging-polarimetry observations of Mars in the second half of the 2003 apparition, using HOPS (Hida Observatory Polarimetry System). Some data showed polarimetric events on Mars, such as morning water ice clouds. Surface polarization was roughly approximately 1 percent (or slightly larger), consistent with the HST (Hubble Space Telescope) polarimetry observation which conducted earlier in 2003. We examined wavelength dependence of linear polarization of the surface and morning water ice clouds. The measured linear polarization was larger, however, the trend was similar to previous works. Much more polarimetric observations should be needed. 資料番号: AA0063350051 |
