(It was a disturbed night, so these results may just indicate that the winds were, indeed, unusual.) I checked the original spectra using SDI_XYPL.PRO - the spectra look great. ASC does not suggest cloud until the very end of the night. So, for now, I think the light winds in the midnight sector are real. (A similar result was obtained on March 05.) Both 6300 and 4278 MSP channels failed! Entry at 18:50 UT, MC. Updated, 03-10-98, 05:45 UT, MPK.
