A Coronal Mass Ejection (CME) and the associated coronal dimming
The SXT observes the development of a CME accompanied
by strong cooling in the locality. The
use of lightcurves shows the general cooling and heating associated with
the active region as the region becomes devoid of the hot plasma that eventually
is ejected outwards into the corona.
A comparison between the SXT and EIT
Solar images from the SXT and Extreme-ultraviolet
Imaging Telescope (EIT) are compared. Active regions appear in similar
places in the images but their details vary. The results complimenting
one another, producing a better over-all picture of the Sun, revealing
the subtleties of the Sun's magnetohydrodynamics.
Impulsive flares in the tremendously active region AR8100
A brief nugget showing how the sustained activity of this region raised
the background levels of soft X-ray. The impulsive flares associated
with the region were well observed by the SXT and full Sun movies over
this period are available to view.
The motion of an LDE across the solar surface
In this nugget an eruptive Active Region (AR) spawns
a Long Duration Event (LDE), consisting of a strong ejection to the
north followed by a western ejection that decelerates across the surface
perhaps due to its field lines impinging on overlying closed field lines.
Solar flares with short and long decay components
The active region AR8108 produced several C class
flares and an LDE. The flares show an impulsive component superimposed
upon a slow decay. The LDE is shown to leave behind a characteristic
cusp structure. Both are viewable as movies.
A well observed and unusually oriented flare
The SXT observed this unusual flare which appears
to have the typical loop structure albeit lying in the plane of the solar
surface, the ejecta is perhaps following pre-existing loops which rejoin
with the surface. A movie of the event shows that it flares twice.
Has the new Solar cycle begun?
X-ray flux measurements show what seems to be a minima
corresponding to the minima of the solar cycle, the maximum should
be reached around the year 2000. The X-ray intensity can change by
a factor of 100 in a cycle, but why does it appear that a smaller variation
is seen in other stars?
A huge slowly decaying arcade preceding a vast CME
The SXT observed a large arcade, about 0.6 solar
radii in extent, decaying slowly over the period of about a week.
A massive CME associated with this long duration event was observed by
LASCO, results that may illuminate the 3D development of such arcades.
An elusive trans-equatorial interconnection between regions
Between the 25th and 26th of December two active
regions on either side of the equator at low latitudes became clearly connected.
The process of connection was not observed and the mechanisms remain somewhat
mysterious, future nuggets may well reveal the secrets of this observation.
