Observation Sector 73

TESS Observation Sector 73 is comprised of observations made during orbits 153 and 154 of the TESS mission. Observations extend from December 7, 2023, through January 3, 2024. 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 73

During Sector 73, 12,000 stars will be observed at two-minute cadence, up to 2,000 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 given on the Target List page. The target list includes the camera and CCD on which the target can be found, TIC ID, RA, declination, and TESS magnitude.
