Target Info

Target Name: NGC 4151
Target No.: 1680
Category: ACTIVE GALAXIES AND QUASARS
Coordinates[J2000]: (182.63575, 39.40573)
Exp (ks): 60
Extended: N

Extent Size:

Background Restriction: N

Remarks:

Constraint Details

Monitor: Y

Criteria: TESS is observing NGC 4151 at 10 minute cadence from MJD 59636.000 to 59664.468. NICER observations should try to cover this time as evenly as possible, on average 4 times per day. Each visit should be 0.6 ks. We do not require strictly regular sampling. Two visits per day would also still be valuable.

Phase Dependent: N

Specific Time: Y

Start: 2022-02-26 00:00 UTC
End: 2022-03-26 11:14 UTC
Remarks: This is the period over which TESS will be observing NGC 4151. Please note that TESS will break off observations from MJD 59649.5 to 59651 to download data, and NICER should avoid observing NGC 4151 at this time. Monitoring should be at least 20 days over this window. More complete coverage of the 28 day window is better.

ToO: Y
Coordinate Observation: Y

Observatory: TESS
Description: TESS will automatically observe NGC 4051 at 10 minute cadence in its Full Frame Images. This DDT request is complimentary to Cycle 4 proposal 5160, which targets NGC 4051. (The DDT request is during the same same time window as NGC 4051).

Uninterrupted: N
