P. Miralles: Lead Scientist ---------- R. Wu: Commander Y.-K. Ko: Planner M. Uzzo Command file: 03.10.30.16:05:00.cmd.log Activity: --------- 1) UVCS in Soft Safe Configuration Sequence: Manual SCI_SPEC: Coronal Hole observation was interrupted due to high proton flux associated with an X18 Solar Flare which occured at approximately 2041 UT, 29 October 2003. This information concerning the flare was passed to UVCS team by Mauna Loa Solar Observatory. Additional information from RHESSI Major Flare Watch update: Solar activity remains high. Active region NOAA 0486 produced another large (X10) flare on 29-Oct-2003 20:37 UT, accompanied by a proton event and halo CME. Further C- and M- class event expected with a good chance for another X-class flare.
