SOHO's latest "Picture of the week" edition released great graphic illustration of combination of Sun-observing spacecrafts coverage of solar events.
From their positions near the Sun-Earth line, SDO and SOHO observed small CME on July 4, 2013. At
By combining different images of the Sun, taken almost at the same time on June 7, 2013, the underlying magnetic structure of the Sun and how it appears above the solar surface can be revealed. SDO engineers combined a magnetic image of the Sun, where darker and
In the three years since it first provided images of the sun in the spring of 2010, NASA’s Solar Dynamics Observatory (SDO) has had virtually unbroken coverage of the sun’s rise toward solar maximum, the peak of solar activity in its regular 11-year cycle. This video
NASA’s Solar Dynamics Observatory (SDO) has eclipse seasons twice a year near each equinox. Earth passes directly between the Sun and produces a series of eclipses from the point of view of the spacecraft.The first eclipse of the SDO Spring 2013 Eclipse Season
NASA/SDO released a short video which covers January 5 through 7 and shows the 171 angstroms channel, which is especially good at showing coronal loops – the arcs extending off of the Sun where plasma moves along the magnetic field lines. The brightest spots
JHelioviewer is visualization software that enables everyone, anywhere to explore the Sun. Developed as part of the ESA/NASA Helioviewer Project, it provides a desktop program that enables users to call up images of the Sun from the past 15 years. Software contains
While trying to access SOHO’s coronograph data we noticed that the latest LASCO C2 image is updated on August 18 at 13:36 and LASCO C3 at 13:30. Also, SOHO’s EIT 304 latest image is from August 17 at 13:19, EIT 195 is from August 16 at 13:13 while EIT 171 and 284 show
A comet discovered by amateur astronomers on Friday, Sept. 30th, disintegrated in spectacular fashion the very next day when it plunged into the sun. The Solar and Heliospheric Observatory recorded the comet’s last hours. The end was punctuated by an unexpected
On October 1st around 10:17 UT, widely-spaced sunspots 1302 and 1305 erupted in quick succession, revealing a long-distance entanglement which was not obvious before. NASA’s Solar Dynamics Observatory (SDO) recorded the movie of the double blast:Since it was
Today, NASA’s Solar Dynamics Observatory is monitoring sine wave 400,000 km long. It’s an enormous filament of magnetism slithering over the sun’s northeastern limb:One of the wave troughs appears to be passing through the core of sunspot 1282. If so, an eruption
