Observation Sector 115

TESS Observation Sector 115 is comprised of observations made during orbits 241 and 242 of the TESS mission. Observations extend from March 14 through April 12, 2027. Sector 115 is the first of two ecliptic sectors. The regions of the sky observed are shown at right.

Pointing

The orientation of the spacecraft and camera boresights are given in the table below.

Boresight	RA	Dec	Roll	Ecliptic Longitude	Ecliptic Latitude
Spacecraft	219.645	-16.063	-108.654	222.3	-0.6
Camera 1	185.767	-2.475	-24.311	186.3	0.0
Camera 2	208.030	-11.931	-21.475	210.3	-0.4
Camera 3	231.711	-19.545	165.049	234.3	-0.7

All coordinates are degrees (J2000)

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 115

During Sector 115, 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.
