MLSO Special Observing Campaigns

HAO encourages special observation requests to maximize scientific discovery for the solar and heliospheric community. Visit MLSO's new Special Observing Campaign page to learn more about past observations and how to apply for instrument time for your own scientific needs.

Funding Approved for New Coronagraph

NCAR/ESSL has approved funding for a new coronagraph to replace the aging Mk4 instrument. Keep track of this exciting development on our New Coronagraph page. The Mk4 is still offline while a new camera is being installed and tested. Thank you for your patience.

PICS Narrow-band Limb Images

The PICS instrument is now serving images of the limb taken with a narrow-band H-alpha filter. The new data replaces the broad-band images in the MLSO data portal, and its first date of appearance was May 5th, 2009. The animation to the left shows narrow-band limb images of prominence activity occurring at approximately 21:08 UT on May 8th, 2009.
