Fig.10 A study of preflare plasma in
flare-productive active region (FPAR) using spectral and
|
|
|
|
polarization
data. One dimensional scans of AR
9393 (located near the meridian) at several
|
|
|
|
wavelength
is presented. The short-wave polarization inversion is observed one day
before power
|
|
|
flare
occured at 10h 15m UT in AR 9393.
