Image credit: NASA / ESA / SOHO LATEST LASCO/SOHO REAL TIME IMAGES We maintain an archive of the most recent ~12 days of LASCO data as gif images in three different resolutions: large (1024x1024), medium (512x512), and small (256x256).We can't always promise these are up-to-date SOHO webcam: LASCO C3. SOHO, the Solar & Heliospheric Observatory, is a project of international collaboration between ESA and NASA to study the Sun from its deep core to the outer corona and the solar wind The SOHO-number also provides a link to positional information for that comet. See note below. DISCOVERER(S): Names of the people who first reported the comet. TELESCOPE(S): A list of telescopes in which the comet was visible. This may include SOHO (LASCO C2, C3 and/or SOHO/SWAN), and STEREO cameras (COR-2A, COR-2B, HI-1A, HI-1B) The Large Angle and Spectrometric Coronagraph (LASCO) on board the Solar and Heliospheric Observatory satellite (SOHO) consists of three solar coronagraphs with nested fields of view:. C1 - a Fabry-Pérot interferometer coronagraph imaging from 1.1 to 3 solar radii; C2 - a white light coronagraph imaging from 1.5 to 6 solar radii (orange) C3 - a white light coronagraph imaging from 3.7 to 30.

So far, some 15% are not Kreutz group sungrazers and only 4% are not members of the other three groups. Further background information on the SOHO comets can be found at the LASCO Comet site

The SOHO/LASCO CME Catalog in the LASCO/C2 field of view (FOV) and the central position angle (CPA). More than 10 CMEs can occur on a single day, and many CMEs can appear at the same time in the C2 FOV. The CPA can essentially distinguish these CMEs appearing simultaneously The planets Mercury and Jupiter are the closest to the Sun right now, but they are too far away to be seen in those LASCO C2 frames, and they move much slower. One of my guesses is that those are stars, and the perceived motion is simply due to SOHO orbiting the Sun Soho has gone down in another bakeout phase but look what the C2 Lasco camera captured before the pics were shut off.

We present a photometric calibration of the SOHO/LASCO-C2 coronagraph based on the analysis of all stars down to magnitude V=8 that transited its field of view during the past 14 years of operation (1996 - 2009), extending the previous work of Llebaria, Lamy, and Danjard (Icarus 182, 281, 2006).The pre-processing of the images incorporates the most recent determination of the. This movie is a combination of SOHO/EIT at 195 angstroms as well as the LASCO/C2 and C3 cameras. At this scale we can see the flashes from solar flares in SOHO/EIT (green) and the subsequent coronal mass ejections in SOHO/LASCO/C2 (red) and SOHO/LASCO/C3 (blue) Figure 9: SOHO/LASCO C2 image extract showing the non-group X/Comet XC-87. The object was only visible in five images, appearing rather condensed, suggesting it may be an allignment of cosmic rays. However, the very consistent nature of its appearance is strongly in favour of a true comet, hence its X/comet status Here the comet is seen by SOHO LASCO C2 when somewhat closer to the Sun. The LASCO coronagraph on SOHO, designed for seeing outbursts from the Sun, uses a mask to block the bright rays from the visible surface. It monitors a large volume of surrounding space, and as a result has become the most prolifi

The Solar and Heliospheric Observatory (SOHO) is a spacecraft built by a European industrial consortium led by Matra Marconi Space (now Airbus Defence and Space) that was launched on a Lockheed Martin Atlas II AS launch vehicle on December 2, 1995, to study the Sun.It has also discovered over 4,000 comets. It began normal operations in May 1996 SOHO LASCO C3 coronograph makes possible to extend ground based image composed with SOHO LASCO C2 image up to 30 solar radii.

The LASCO detection rate is subjective to the image cadence. In 2010 when the EIT instrument on board SOHO was shut off, the C2 image cadence nearly doubled. This lead to a sharp increase in detections. The image rates are now provided in the catalog so that this effect can be normalized Two comets in same SOHO field of view - posted in Solar System Observing: There were two comets appearing in the same field of view in SOHO LASCO C2 images around 2021-Jan-18 01:40 UT The brighter one can be seen on the left and was moving toward the sun before it disintegrated. The fainter one was in the lower right of this frame approaching the sun before it disintegrated The SOHO LASCO C2 instrument captured this image of the Earth-directed coronal mass ejection or CME.
