Knowledge of amplitudes of the first harmonic [a.sub.l1] and [b.sub.l1] of the magnetic field of the TL allows by using the relation (7) to build its magnetogram
Bottom: This magnetogram image shows north- and south-oriented magnetic fields emerging from and descending through the Sun's surface.
A Kitt Peak National Solar Observatory magnetogram taken in Arizona at 14:58:52 UT confirmed the earlier subflare activity but was too early to help elucidate our observation.
In order to study the action of the convective plasma motions, in particular the vortices, on the magnetic configuration of the region, we study the sequence of MgI magnetograms where we identify magnetic elements.
Magnetograms at Wilcox have been tracking the sun's polar magnetism since 1976, and they have recorded three grand reversals-with a fourth in the offing.
The MTM magnetograms demonstrated a relationship of pipeline pressure with the certain anomalies.
Nine posters join the one keynote, 12 invited and 27 contributed talks represented here, and the collection covers flows around active regions on the surface and below (including surface flows from magnetograms and large eddy simulation of solar photosphere convection with realistic physics), flux emergence and cancellation (including hinode observations of flux emergence in quiet an active regions), space weather and active regions from back to front (including challenges created by active regions in global models), the morphology of active regions and filaments (include the life and death of solar active regions), and magnetic flux and magneto-acoustic waves (including a report on the interaction between magneto-acoustic waves and magnetic fields).
The plages are emission regions tied to strong magnetic fields and are nearly identical to the shape of the magnetic regions visible on solar magnetograms. When several spot groups, or active regions, he very close together you might have difficulty in white light telling which spots are in which regions.
