HURRICANE CARLOTTA SPINS IN …

7/7/00
Date 7/7/00
Description With winds reaching 250 kilometers per hour (155 mph), this year's Hurricane Carlotta became the second strongest eastern Pacific June hurricane on record. New images from NASA's Multi- angle Imaging SpectroRadiometer (MISR) show the hurricane on June 21, the day of its peak intensity. MISR, built and managed by NASA's Jet Propulsion Laboratory in Pasadena, Calif., is one of several Earth-observing instruments aboard NASA's Terra satellite, which was launched in December 1999. This set of images has been oriented so that the spacecraft's flight path is from left to right, north is at the left. The top image is a color view from MISR's vertical (nadir) camera, showing Carlotta's location in the eastern Pacific Ocean, about 500 kilometers (310 miles) south of Puerto Vallarta, Mexico. The middle image is a stereoscopic anaglyph created using MISR's nadir camera plus one of its aftward-viewing cameras, and shows a closer view of the area around the hurricane. Viewing with red/blue glasses (red filter over the left eye) is required to obtain a 3-D stereo effect. Near the center of the storm, the eye is about 25 kilometers (16 miles) in diameter and partially obscured by a thin cloud. About 50 kilometers (31 miles) to the left of the eye, the sharp drop- off from high-level to low-level cloud gives a sense of the vertical extent of the hidden eye wall. The low-level cloud is spiraling counterclockwise into the center of the cyclone. It then rises in the vicinity of the eye wall and emerges with a clockwise rotation at high altitude. Maximum surface winds are found near the eye wall. The bottom stereo image is a zoomed-in view of convective clouds in the hurricane's spiral arms. The arms are breeding grounds for severe thunderstorms, with associated heavy rain and flooding, frequent lightning, and tornadoes. Thunderstorms rise in dramatic fashion to about the same altitude as the high cloud near the hurricane's center, and are made up of individual cells that are typically less than 20 kilometers (12 miles) in diameter. This image shows a number of these cells, some fairly isolated, and others connected together. Their three-dimensional structure is clearly apparent in this stereo view. More information about MISR is available at: http://www-misr.jpl.nasa.gov MISR scientific data products are available through the Atmospheric Sciences Data Center at NASA Langley Research Center: http://eosweb.larc.nasa.gov The Terra mission is managed by NASA's Goddard Space Flight Center, Greenbelt, Md. JPL is a division of the California Institute of Technology in Pasadena. #####
With their 2048 x 2048 frame …
Description With their 2048 x 2048 frame size and images as often as every 2.5 minutes, STEREO images in the extreme ultraviolet wavelength provides us with the opportunity to pick out any part of the Sun and zoom in for a much closer look. We picked out one active region (September 6, 2007) and magnified our view of that area 10 times from the image showing the entire Sun. Even with a full screen view of the original frame, details of this active region are difficult to discern. But, the close-up still and the movie frames reveal subtle details of lighter loops of plasma arcing and slowly changing above this active region. These trace the magnetic field lines that rise out, above, and connect back into the solar surface. The looping patterns shift and sway over this 15 hours period, but do not generate any solar storms. When the Solar Dynamics Observatory launches and begin operations in about year or so, it will offer much faster frame rates and even more detailed images of the Sun.

Description Actually, no. This is what we might call a "manufactured" 3D Sun. It was produced by combining two SOHO images from its EIT 195 instrument that were taken 10.5 hours apart on October 23, 2007. Because the Sun rotates once every 27 days or so (about 13 degrees per day then), by using two images almost half day apart, we are achieving about 6 degrees of changed perspective. That is enough to produce a kind of 3D effect - but, of course, the Sun has changed some in those 10.5 hours. To get real 3D, such as the STEREO mission was able to produce for a period of time, you need images taken simultaneously from two different perspectives not too far apart. Still, having said all that, it makes for an eye-catching and interesting image. The most noticeable feature is the large and dark coronal hole that can be seen just right of and below center. It is spewing out high-speed solar wind that could cause aurora to be visible in higher latitudes on Earth several days later. The video clip fades back and forth between one 2D image and the 3D image. Note: You can learn how to create 3D images here [ http://stereo.gsfc.nasa.gov/classroom/3d.shtml ]

Abstract This movie shows the south pole of the Sun from the two STEREO spacecraft using the 171 Angstrom filter in the Extreme UltraViolet Imager (EUVI). This filter reveals ionized iron (Fe+8=Fe IX, Fe+9=Fe X) which forms at temperatures above 1.3x106K, and flows along the magnetic field lines of the solar active regions. New active regions come into view as the Sun rotates.

Title Rotating Tour of Solar Coronal Loops
Abstract A slow rotating tour of a data-based coronal loop model. This version is designed for continuous loop play. The solar model is constructed from magnetogram data collected by SOHO/MDI. Because we do not see the full solar surface at any one time, the magnetograms collected over the course of a solar rotation are processed through a time-evolving solar surface model to provide a snapshot of the surface at a fixed time. The resulting magnetogram is then processed through the Potential Field Source Surface (PFSS) model. Coronal loops are visible at the higher temperatures of ultraviolet light, in this case, 195 Angstroms, the filter wavelength of SOHO/EIT.

Abstract The two STEREO spacecraft, A (red path) and B (yellow path), are launched from the Earth into a highly eccentric orbit with an apogee that reaches the orbit of the Moon. Once in this orbit, the trajectories are adjusted so they can receive gravity-assists from the Moon. The gravity assist will send them both into heliocentric orbits, one spacecraft ahead of the Earth and the other behind the Earth. This trajectory was generated using a spacecraft ephemeris generated shortly after launch.

Title Grand Tour of the Coronal Loops Model
Abstract This is a longer coronal loops tour combining components of the two previous versions (Animation IDs 3286 and 3287). The solar model is constructed from magnetogram data collected by SOHO/MDI. Because we do not see the full solar surface at any one time, the magnetograms collected over the course of a solar rotation are processed through a time-evolving solar surface model which provides a snapshot of the surface at a fixed time. The resulting magnetogram is then processed through the Potential Field Source Surface (PFSS) model which constructs the magnetic field above the solar surface. The magnetic field around the Sun is then analyzed for field lines, which creates the loop structures we see in the model. Hot plasma tends to flow along the magnetic field lines, creating the coronal loops. These loops are only visible at the higher temperatures corresponding to ultraviolet light, in this case, 195 Angstroms, one of the filter wavelengths of SOHO/EIT. For this version, we color the coronal loops green for ready comparison to the EIT 195 Angstrom imagery using the EIT 'standard color table'.

Title Grand Tour of the Coronal Loops Model
Abstract This is a longer coronal loops tour combining components of the two previous versions (Animation IDs 3286 and 3287). The solar model is constructed from magnetogram data collected by SOHO/MDI. Because we do not see the full solar surface at any one time, the magnetograms collected over the course of a solar rotation are processed through a time-evolving solar surface model which provides a snapshot of the surface at a fixed time. The resulting magnetogram is then processed through the Potential Field Source Surface (PFSS) model which constructs the magnetic field above the solar surface. The magnetic field around the Sun is then analyzed for field lines, which creates the loop structures we see in the model. Hot plasma tends to flow along the magnetic field lines, creating the coronal loops. These loops are only visible at the higher temperatures corresponding to ultraviolet light, in this case, 195 Angstroms, one of the filter wavelengths of SOHO/EIT. For this version, we color the coronal loops green for ready comparison to the EIT 195 Angstrom imagery using the EIT 'standard color table'.
