Target Info

Target Name: MRK 335
Target No.: 6001
Category: ACTIVE GALAXIES AND QUASARS
Coordinates[J2000]: (1.58134, 20.20291)

Constraint Details

Monitor: Y

Criteria: The request is to monitoring with NICER at a level of 2 ks per day for each of the about 3 days Chandra is looking (DDT submitted), in the next 5-20 days. And then if possible to supplement with another 2 ks on either side of the Chandra run. We thus request at least 6 ks, and ideally 10 ks of total exposure.

Specific Time: Y

Start: 2020-06-23 00:00 UTC
End: 2020-07-08 00:00 UTC
Remarks: The specific time range for this observation aims to catch the source while it is in an intermediate flux state. As we required for coordinating NICER observations with Chandra and NuSTAR observations, the actual start and end dates strongly depend on the ones from the Chandra DDT (if accepted).

ToO: Y
Coordinate Observation: Y

Observatory: Chandra (& NuSTAR on best effort)
Description: We aim to coordinate NICER observations with Chandra observations, that will be over about 3 days because of its 240 ks total exposure. We thus wish to get 3 NICER exposures during Chandra observation days, and 2 on either side of the Chandra run. NuSTAR is expected to observe simultaneously on a best effort basis, if NICER and/or Chandra DDT observations are accepted.

Uninterrupted: N

Justification:

Estimated Count Rate (cts s-1): 3.600
