dc.description.abstractSince the reported bursting activity of the magnetar 1E 1841-045 with Swift-BAT (ATEL #16784), Fermi-GBM (ATEL #16786), and NICER (ATEL #16789), we have acquired more NICER observations of the target, covering the time period 2024 August 20 at 23:28 to 2024 August 31 at 10:58 UT, for a total exposure of 27.6 ks. Additionally, we acquired a NuSTAR Directors Discretionary Time observation starting on 2024 August 29 at 04:21 UT for a total exposure of approximately 50 ks. Lastly, we analyze the Swift-XRT photon counting mode observation acquired beginning 2024-08-22 at 03:52 UT for a total of 1.8 ks. The NICER monitoring shows that the source bursting activity has strongly diminished since August 20. We detect only two faint bursts in addition to the ones reported in ATEL #16789.
