MEDOC Daily minutes - Wednesday, May 23 2001 -------------------------------------------- Announcement: ------------- Good bye, Giannina who will leave MEDOC to-morrow. Daily meeting of Friday 25 will take place at 11 am local time. SUMER door will be closed next Tuesday. Latest observations (Tuesday 22) ------------------------------- UVCS (G. Poletto) : She reported small flare observations from Sac Peak on Tuesday 22 (SW20 at 14 and 23.30 UT) CDS (D. Pike) : as scheduled. No big activity on AR 9463. SUMER (P. Lemaire) : Test of JOP122 : update of wavelengths Fe X and Fe XI lines in the quiet corona : exposure times of half an hour are OK. Filament oscillations : ok. State of the Sun : ------------------ The southern coronal hole (as seen in 195) could be a good target when crossing (at the limb) the vertical SUMER slit at the end of the week.
