Description:
This objective is that high school students who are observing the sun have interests on Hinode data and compare Hinode data with their own observation data. The observations are performed as HOP173 every summer/winter since 2010. Among astronomical club of high schools in Japan, many of the students observe sunspots and some of them observe especially prominence in H-alpha. This way solar observation by the students is very active, but Hinode data didn't penetrate into them sufficiently. One reason is that they cannot check Hinode image data in real time. Other reason is insufficient data near the their observation time. So, we carry out observation of synoptic, active region and prominence between 11-15JST(2-6UT) to promote joint observations with the high school students. So far, some high schools participated in this joint observation in addition to public observatories and science museums which have solar telescopes. The high school students compare Hinode data with their own observation data and deeply understand solar physics. School teachers use the data for their class and teaching materials. The public observatories and the science museums use Hinode data for their exhibition with their observations. 1. Synoptic observation We would take a synoptic image by XRT at/near 4:00UT(13:00JST) when the students perform daily solar observations, instead of / in addition with the usual synoptic observation at 6:00UT(15:00JST). The students compare their own sunspot observation with corona in x-ray and understand spatial/morphologic relations between sunspots and active regions. 2. Active Region Observations In case active regions are on the disk, we continuously observe one of the active regions by SOT /XRT. The students examine Hinode data in comparison with their own data and understand development of sunspots/active regions. 3. Prominence Observation In case bright/remarkable active regions are not on the disk, we continuously observe prominences. The students who observe prominences in H-alpha filter compare Hinode data with their own data.
