Points Of Interest
- LASCO begins on 03/13 the Joint Polar Study with Hinode/UVCS/STEREO/TRACE/
/SOLIS between 03/13 - 03/20 2007.
This will be in C2 over the South Pole with subfields 18x13 LOCS block
FOV at 100 sec exp. These subfields are attached to the EIT 195 2x2 binned
images to give the south pole program aprox 12 minute cadence.
