Abstract

Swift/BAT reported the detection of possible burst activity from 1E 1841-045 at 19:01:18 UT on 2024 August 20 (GCN #37211). A subsequent notice reported three additional bursts detected by Swift/BAT over the next 24 hours, suggesting that the source has entered a bursting phase for the first time since Swift/BAT last detected it in 2016 (GCN #37222, ATel #16784). Follow-up Fermi/GBM observations detected 8 bursts, 3 of which were also reported by Swift/BAT (GCNs #37222, #37234, ATel #16786). Supplementing its biweekly monitoring campaign, NICER triggered observations of 1E 1841-045 starting on 2024 August 20 at 23:28 UT for a total exposure time of 4.6 ks.
