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.

 

Study relation between magnetic field and topology of solar sources   ??                              Alexander Nindos                   ???

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.

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.

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).
