Data & Observations

MLSO Home Page

On Monday, November 11, 2019, Mercury will transit the Sun for the first time since 2016. Weather permitting, MLSO will again be observing the transit with our K-Cor coronagraph. Be sure to come back and see the data! Shown at left is a movie from the 2016 transit as observed by K-Cor. Look for the small silhouette of the planet moving though the corona. Also, visit our 2012 Venus transit page for more transit movies.


K-Cor L1 data is being replaced by fully calibrated L1.5 data.
Units and data type have changed.  *MORE INFO*

CoMP has been removed from the MLSO spar. Upgraded CoMP (UCoMP) will be deployed to MLSO at the end of 2019, and will provide improved total intensity, linear polarization, magnetic azimuth, and Doppler observations over a wide range of wavelengths from 530nm to 1083nm.
