Observation Sector 39

TESS Observation Sector 39 is comprised of observations made during orbits 85 and 86 of the TESS mission. Observations extend from May 27 through June 24, 2021. 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 39

During Sector 39, 20,000 stars are observed at two-minute cadence, 1000 at 20-second cadence, and full-frame images are collected every 10 minutes.

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.
