INTEGRAL observations of Cygnus X-3
Abstract
Evidence that the HMXB and microquasar Cygnus X-3 has been transitioning to its soft state has been reported since early-May (2010) in ATELs #2609, #2611, and #2635 using all-sky monitors Swift/BAT, RXTE/ASM, and MAXI. This is significant because it would represent the first soft state for Cyg X-3 since the reports that gamma-ray (>100 MeV) flaring seen by Fermi and AGILE is associated with this state.
