sheets). These versions of the PFSS look different than Nariaki's,
but can be very useful for understanding large-scale configuration
of magnetic field. MDI daily intensity images and magnetogram movies.

of vector magnetograms by solving the ideal induction equation;
then, calculate mag. helicity flux; based on LFF extrapolation,
estimate total mag. energy, free mag. energy, and total helicity
in active region. Also provide solutions for 180-deg ambiguity for
each vector magnetogram; the resolved data will be provided both
on image and on heliographic plane and using the line of sight
(longitudinal, transverse) and heliographic (vertical,horizontal)
mag. field components. From IVM archive.

to magnetic and topological parameters of associated IP magnetic
clouds. The necessary steps are:
1) Using an appropriate coronal (or/and chromospheric) image of the
source region together with associated photospheric magnetogram,
derive the chirality (i.e. handedness) of the source's magnetic field.
2) Using the coronal flux rope model for the source region, derive
leading field predicted by the coronal flux rope model (North or South).
3) Get the orientation of the Sun's large-scale dipolar field.
4) Go to IMF data. Derive chirality of magnetic cloud's magnetic
field (check with Lepping MFI tables). Compare the chirality of the
MC's field to the chirality of the source's field.
5) From IMF data, derive the direction of the leading IMF field (north or south).
Compare it with leading field predicted by coronal flux rope (see step 2)
and with orientation of Sun's large-scale dipolar field (see step 3).
Other Solar Data
1) Series of EIT snapshots; IDL Barbara Thompson thompson movies;
2) Series of EIT difference snapshots (in addition to the ones Jie > Mar. 1997 savesets
is doing).
3) De-rotated dimming images for use in mapping
4) Dimming maps with EIT waves, if present (dark gray areas
are active regions, light gray is dimming, dark lines show
wavefronts, dashed lines show possible, faint wavefronts).
I'll save maps so that the limb and locations of the features
correspond to EIT coors., and attach a fits header so that it can
transformed into a map object for comparison with other data.
The area corresponding to the dimming will be also be saved
as an array of heliographic coordinates.

(magnetic cloud-like structure) region and the black-red bars the
magnetic cloud region. THE METHOD AND RESULTS WERE
SUBMITTED TO ANN. GEOPHYS. BY LEPPING, WU, BERDICHEVSKY,
2004. WE WILL REVISE THIS PAPER SOON. I used an program
to identify MC/MCL automatically for all the events listed on the
CDAW website. About 34 of these have a MC and 20 have a MCL in
the event. The averaged velocity, magnetic field also marked on
the figures as a red number.

Microstructures of geoeffective CMEs. Files are: PPT, TXT Ryuho Kataoka kataoka 2 files
1) A list of shock parameters associated with CMEs during
solar cycle 23 [from R. Kataoka,
H. Shimazu, and K. Marubashi, Downstream structures of
IP fast shocks assoc. with CMEs, submitted to GRL, 2005].
2) Solar wind structures during Nov 7-11, 2004 and their solar origins.
My interpretation is summarized in PPT file. This information
may be useful as the first step to understand
complicated solar wind structures, such as multiple shocks,
merged CIR, and/or compressed magnetic clouds during this interval.
Solar Source Identifications
Identification of solar sources (CME, flare, filament, Coronal PNG, GIF, HTML Jie Zhang Zhang_source Various
hole surface source region) for the storms; method as used for major storms
from 1996 to 2000 (Ap.J. 582, 520, 2003): adaptive-window method,
which exploits solar wind speed to narrow backward search window.
Three possibilities for the source/sources of a storm: unique halo CME (U),
multiple halo CME (M), and questionable source (Q); in addition, data gaps (N).
The master table:
