Rebrightening of GRS 1915+105 Observed by NICER
Abstract
On July 9, 2021, MAXI reported a sharp flux increase from the stellar-mass black hole GRS 1915+105. After 26 years of persistent high luminosity and structured variability, GRS 1915+105 faded exponentially in 2018, eventually settling (after a sudden final decrease in mid 2019) at a few percent of its prior apparent brightness (Negoro et al., ATel #11828; Homan et al., ATel #12742).
