LASCO Comet Hyakutake HOME PAGE

Welcome to the Comet Hyakutake page for the Large Angle and Spectrometric COronagraph Experiment (LASCO). The LASCO experiment was launched on the SOHO (Solar and Heliospheric Observatory) spacecraft. SOHO was launched on 2 December 1995 at 0808 UT (0308 EST) from the Kennedy Space Center, Cape Canaveral, Florida.

Comet 1996 B2 Hyakutake Images From LASCO C3 Coronagraph

Perihelion is on May 1, 1996 at 0.231 AU with an elongation of 7.6 degrees.

Minimum Elongation is approx 5.2 degrees and occurs on May 3, 1996

The comet will be in the C3 field of view until May 6, 1996.

On May 1, 1996 there was a coronal mass ejection (CME) seen by the LASCO C3 coronagraph while the Comet Hyakutake was also in the field of view. This provided a spectacular picture of a comet and an explosive solar event in which matter streams out from the sun at hundreds of kilometers per second in a single image. This image was created by subtracting an image prior to the CME from one during the CME. This has the effect of emphasizing the changes in the corona.
