Refinement of Eclipse Planning
Science Nugget: Feb 21, 1998
This week we continued planning our observations for the upcoming solar
eclipse. SXT is currently planning on making a series of quarter-resolution
(256x256) full-sun images in the AlMg filter. The selection of only one
filter for the sequence and the reduction of resolution to 256x256, allow
for a faster cadence of images; we should get one full-sun image every
32 seconds. If a suitable active region is expected to lie along the edge
of the moon's apparent path across the Sun, we also plan to make a sequence
of fast-cadence partial-sun images, in the hopes of getting images of grazing
occultation of the active region.
The rapid motion of Yohkoh makes it whiz in and out of eclipse
several times, as shown in the plots below. Please refer to the planning
page for further details, and we will present a view of the real thing
in our notes for Week 9.
