Extended Abstract Hinode is a solar observation satellite in Japan
and its launch was in September 2006. Its name means “SUNRISE“ in
Japanese. It has three instruments onboard in visible light, X-ray,
EUV to solve mystery of coronal heating and origins of magnetic
fields. <P />Hinode has been providing us with impressive solar data,
which are very important for not only investigating solar phenomena
but also giving new knowledge about the sun to the public. In order
to efficiently communicate Hinode data to the public, we organized
working group for public use of Hinode data. which are composed of both
researchers and educators in collaboration. As follow, we introduce
our activities in brief. <P />For the public use of Hinode data, at
first, we produced two DVDs introducing Hinode observation results. In
particular, second DVD contains a movie for kids, which are devloped
to picturebook. Now, it is under producing an illustrated book and
a planetarium program. It turn out that the DVDs help the public
understand the sun from questionnaire surveys. Second, we developed
teaching materials from Hinode data and had a science classroom about
the sun, solar observations, practice with PC such as imaging software
at junior high school. As the results, they had much interests in Hinode
data. Third, we have joint observations with high school students and so
on in a few years. The students compare their own data with Hinode data
and have a presentation at science contests. The joint observations make
their motivation higher in their activities. <P />It is important to
record and report our activities in some ways. So, we positively publish
papers and have presentions in domestic/international meetings. Though
we are supported in budget, resources and so on by NAOJ Hinode Team,
we apply research funds for promoting our EPO activities and acquire
some funds such as NAOJ Joint Research Expenses and Grands-Aid for
Scientific Research Funds since the launch. <P />This way, since its
launch, we have continued various and constant EPO activities for the
public use of Hinode data and have been giving intense impacts and
high interest to the public. As the result, our activities contribute
in further extension of Hinode Mission. Those are quite unique and
would be reference of other similar ones. Hinode is now operating
and solar activities might get more higher. <P />As long as SUN RISE,
we would GO FORWARD!!

Title: Education and Public Outreach Activities with Hinode Satellite
Data

A.; Suzuki, D.
2012ASPC..454..457Y Altcode:
Hinode data are very important for not only investigating solar
phenomena but also giving new knowledge about the sun to the public
and the educational communities, such as public observatories,
planetarium, science museum, and of course, schools. In order to
help the educators to efficiently and actively use Hinode data, we
organized working group for public use of Hinode data. It is a peculiar
point that members of the working group are of both researchers and
educators. That draw an interchange between researchers and educators,
and promoting the various type of activities in collaboration. As
our main activity, we have already produced two kinds of DVDs for
introducing the observational results of Hinode. The DVDs have already
been distributed to the educational communities in Japan. We made
some kinds of surveys for educators to confirm the efficiency of the
DVDs for education and public outreach. In addition, we use Hinode
data to develop educational materials and carried out exhibitions
at some museums. In such way, our activities might be quite unique
in that researchers/educators collaborate each other and a new style
of education and public outreach. In this paper , we introduce these
activities in details and the public impact.

Title: Super-Resolving THEMIS Data for Improved Temperature,
Composition, and Spatial Resolution
Authors: Hughes, C. G.; Ramsey, M. S.; Tonooka, H.
2007LPI....38.1810H Altcode:
The current study investigates the applicability of a super-resolution
algorithm to the fusion of THEMIS visible and infrared data, to
enhance image interpretation and aid in the search for sub-pixel scale
temperature and/or compositional anomalies.

Title: Three-Dimensional MHD Simulations of the Emergence of Twisted
Flux Tubes
Authors: Matsumoto, R.; Tonooka, H.; Tajima, T.; Chou, W.; Shibata, K.
2000AdSpR..26..543M Altcode:
We carried out three-dimensional magnetohydrodynamic (MHD) simulations
of the emergence of a twisted magnetic flux tube initially imbedded
in the convection zone. When the magnetic twist exceeds a threshold
value, the flux tube deforms itself into a helical structure through
the kink instability. For sufficiently long wavelength perturbations
(λ<SUB>p</SUB> > 10H, where H is the local scale height), the
flux tube also subjects to the undular mode of the magnetic buoyancy
instability (Parker instability). The emergent portions of such
helically deformed, undulating flux tube show a series of S-shaped
X-ray emitting regions as observed by the Yohkoh satellite

Title: Simultaneous Hα and X-ray Observations of Prominence Eruption
and Disappearance
Authors: Tonooka, H.; Matsumoto, R.; Miyaji, S.; Martin, S. F.;
Canfield, R. C.; Reardon, K.; McAllister, A.; Shibata, K.
2000AdSpR..26..473T Altcode:
Prominence eruptions or disappearances observed with an Hα limb
filtergraph can be classified into 3 categories, the eruptive
prominence, the quasi-eruptive prominence, and the disappearing
prominence. We investigated their mechanism by comparing the results
of simultaneous observations by Yohkoh SXT and Hα. We found that soft
X-ray features change in both eruptive prominences and quasieruptive
prominences, whereas no significant change takes place in disappearing
prominences.In one prominence eruption event soft X-ray cusp structure
suggests that the reconnection point is just below the Hα prominence

Title: Temperature and emissivity separation from ASTER on EOS AM-1 -
preflight validation by ASTER airborne simulator
Authors: Rokugawa, S.; Matsunaga, T.; Tonooka, H.; Tsu, H.; Kannari,
Y.; Okada, K.
1999AdSpR..23.1463R Altcode:
The thermal infrared sensor of ASTER on EOS AM-1 will provide surface
kinetic temperature and spectral emissivity. The temperature and
emissivity separation(TES) algorithm of ASTER is based on the empirical
relation of emissivity spectra. Prior to this study, TES algorithm has
been validated by spectrum of rock samples or low spectral resolution
airborne field data. Thus this study is the first validation test of
ASTER TES by using the actual TIR field data with very high spectral
resolution. Newly developed ASTER airborne simulator(AAS) was used
to obtain this kind of TIR data, which has the capability to obtain
the multispectral TIR data with 0.2μm spectral resolution. The field
test site was Cuprite, Nevada. The basaltic zone, silicified mountain
and playa are typical targets of the flights. ASTER simulation data
sets were synthesized from the AAS data. Then ASTER TES algorithm was
applied to these simulation data to extract the temperature and the
emissivity. These are compared with the actually measured spectral
characteristics of samples. As the results, the derived emissivity
spectra have a good agreement with those of sample data. Then the
validity of ASTER TES algorithm was demonstrated.
