SOHO Pick of the Week
Active Region in Profile
NEW
May 30 - Jun. 05, 2009
We watched and waited as an active region, shown here in extreme UV light, rotated to the edge of the Sun as seen by STEREO Behind (May 18-19, 2009). Near the edge the coils of magnetic loops that rose above this active region were easily defined against the darker backdrop. The graceful arcs shift and change as the magnetic forces tug and pull at them. What one is actually seeing are particles spinning along the magnetic field lines and revealing the intense magnetism of active regions.
 
Solar, Earth Atmospheric and Climate Video of the Week
NASA's Heliophysics Great Observatories Study the Sun and Geospace
NEW
Dec. 22- 29, 2008
Heliophysics is a term to describe the study of the Sun, its atmosphere or the heliosphere, and the planets within it as a system. As a result, it encompasses the study of planetary atmospheres and their magnetic environment, or magnetospheres. These environments are important in the study of space weather.

Engineers move toward a better understanding of space weather conditions that affect our lives

Feb. 11, 2009
For the past 15 years, engineers and scientists have gained a greater understanding of global warming, the effects of geomagnetic storms, the impact of the solar wind interacting on the magnetized region around the earth, and other dynamic processes that occur in the Earth's near-space environment.
Ulysses Reveals Global Solar Wind Plasma Output at 50-Year Low

Sept. 23, 2008
Data from the Ulysses spacecraft, a joint NASA-European Space Agency mission, show the sun has reduced its output of solar wind to the lowest levels since accurate readings became available. The sun's current state could reduce the natural shielding that envelops our solar system. "The sun's million mile-per-hour solar wind inflates a protective bubble, or heliosphere, around the solar system. It influences how things work here on Earth and even out at the boundary of our solar system where it meets the galaxy," said Dave McComas,
 
Costello Geomagnetic Activity Index

Larger Version
Credit: NOAA / SEC
This graphic shows the latest output over the past 24 hours in two panels. The top panel plots the magnitude of the predicted index in Kp units and the 3-hour interval over which the prediction is valid (solid bar for the latest and dotted for older predictions). Error bars are plotted on the most recent prediction to show the 50% confidence interval. The most recent observed estimates of the Kp index, as determined by the US Air Force, are overplotted in blue. The predictions are color coded according to the amount of solar wind data that was available for each model run, ranging from green (most data) to yellow (little data). The bottom panel plots the lead time of the prediction, which is the propagation time from L1 to the Earth. Note that the lead time points are plotted at the model run time whereas the corresponding prediction points in the top panel are plotted at the model valid time (run time + propagation time), which is usually 30-90 minutes into the future.

The Costello Geomagnetic Activity Index model was developed by Kirt Costello at Rice University under support from the US Air Force and Sterling Software, Inc. It is a neural network algorithm that was trained on the response of the Kp geomagnetic activity index to solar wind parameters. The model takes the most recent two hours of solar wind data and returns a 3-hour activity index prediction in units of Kp. The valid time of the prediction is indicated on the output graphics by horizontal bars. SEC's test product based on this model is an estimate of the geomagnetic activity level, in Kp units, generated every 15 minutes.

MDI Farside Image

Credit: Stanford University
These images are whole-Sun maps of magnetic activity. They show 360 degrees of longitude in the Carrington coordinate system normally used for solar observations. The map extent is from south pole to north pole in an equal area projection. The solar equator and each 60 degrees of longitude are marked.

The Earthside, or near-side, data are smoothed magnetic flux as measured by MDI. The images are shown to 70 degrees from disk center. Each magnetogram takes only one minute to observe.

The farside images are maps of wave speed variations with locations of faster wave speed shown darker. These darker regions indicate locations where there is an accumulation of magnetic field on the far surface. The farside images can only be computed out to 45 degrees from the farside disk center as (un)seen from Earth. A full 24-hours of MDI surface velocity data is used to compute each image.

Highlights of Solar and Geomagnetic Activity
18 - 24 May 2009

Solar activity was very low. No flares were observed. New-cycle
polarity Region 1017 (N18, L=184, class/area Bxo/020 on 14 May) was
numbered on 13 May. It was inactive and simply-structured during the
period and rotated off the disk on 24 May as spotless plage.
New-cycle polarity Region 1018 (S33, L= 046, class/area, Bxo/030 on
23 May) was numbered on 23 May. The region decayed as spotless
plage on 24 May. The region was inactive during its short lifespan.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at
normal levels during the period.

Geomagnetic field activity was at quiet levels at all latitudes
during most of the period. However, activity briefly increased to
active levels at high latitudes on 22 May. ACE observations
indicated the active period (22/1500 - 22/1800 UTC) was due to solar
wind changes associated with a period of sustained southward IMF Bz
(minimum - 4 nT) and a modest increase in velocities (approximately
370 km/sec).

Forecast of Solar and Geomagnetic Activity
27 May - 22 June 2009

Solar activity is expected to be very low.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at normal flux levels.

Geomagnetic field activity is expected to be at quiet levels through
02 June. Activity is expected to increase to mostly unsettled levels
during 03 - 05 June with a chance for active levels at high
latitudes on 04 June due to a recurrent coronal hole high-speed
stream. Mostly quiet conditions are expected during 06 - 09 June.
Activity is expected to increase to quiet to unsettled levels on 10
- 11 June due to a recurrent coronal hole wind stream. Mostly quiet
conditions are expected during 12 -22 June.

PCW Memorial Observatory Solar Observations by Erika Rix
Solar prominences in h-alpha, eastern limb
NEW
Feb. 24, 2009
Observation Date 2009 Feb 24, 1510UT – 1600UT
The eastern hemisphere, especially east to the northeast, was scattered with prominences. As transparency improved, details of these little prominences came to light. The most obvious set was around 90° position angle and then a squat hedgerow one around 40°. I stopped my first sketch midway and began a fresh one with a larger limb span to include the majority of them, most which were faint and whispy or very tiny.
Solar prominences in h-alpha, eastern limb
NEW
Feb. 24, 2009
Observation Date 2009 Feb 23, 1519UT – 1555UT
A fairly tall prominence stood out on the eastern limb that looked like a pair of hands loosely pressed together in prayer. Par for the course on these larger delicate features, they look almost detached until you concentrate on that area for a more in depth look. This is the prominence I concentrated on for the observation sketch. There was another smaller prom just north on the western limb close to a position angle of 290-300 degrees
 
PCW Memorial Observatory Archive

Over thirty, ahem, something years ago, I can vividly recollect my grade school teacher gathering up a large box in her arms and asking the class to follow her. We were going on an excursion and I was filled with excitement. Anything to get me out of the classroom with our little wood desks and beat up textbooks was a fine idea by my standards. I was always more of a “hands on” person and thrived on adventure.

When we reached our destination, any momentary disappointment of being led into the gymnasium soon turned into a flutter of anticipation when we quietly followed her up on the stage and she then turned off all the lights after pulling the huge stage curtains shut. You could hear all my classmates inhale from surprise at the sudden darkness, myself included. It was soon followed by giggles when out of the darkness a flashlight clicked on and the only sight to be seen was my teacher’s smiling face. I remember her well. She was one of my favorites, very kind, and full of wonder.

The next hour we all sat there cross legged, wide eyed in a circle around her as she explained to us about the our solar system. It seemed as if she had several floating hands rotating the model planets in midair around our sun, the flashlight. It was amazing and left a remarkable impact on me.
