Observation Sector 111

TESS Observation Sector 111 is comprised of observations made during orbits 233 and 234 of the TESS mission.  Observations extend from November 26, 2026 through December 22, 2026. Sector 111 is the thirteenth of sixteen consecutive “rolled” sectors focusing on the southern ecliptic mid-latitude range. The regions of the sky observed are shown at right.

Map of TESS camera fields-of-view in ecliptic coordinates.  Camera 1 is red, camera 2 is magenta, camera 3 is blue, camera 4 is green.  The field of camera 4 looks distorted because it is centered on the ecliptic pole. The thin black line is the ecliptic; the thick black line is the galactic plane.

Targets for Sector 111

During Sector 111, 12,000 stars will be observed at two-minute cadence, up to 3,000 stars at 20-second cadence, and full-frame images will be collected every 200 seconds.
The list of targets observed at two-minute cadence are posted on the Target List page as soon as they have been determined. The target list includes the camera and CCD on which the target can be found, TIC ID, RA, declination, and TESS magnitude.
