Abstract
We report the first results of a large multiwavelength campaign of GRS 1915+105 performed between 2005 October 16 to October 18 with Suzaku, INTEGRAL, RXTE, Swift, Spitzer, and ground observatories including Subaru, ESO/NTT, REM (infrared), VLA, ATCA, Nancay, Ryle, and RATAN (radio). GRS 1915+105 was firstly in the stable state with a 6 Hz QPO but then entered into the oscillation phase identified as Class θ. The Suzaku spectra in the 1-80 keV band are very soft, approximated by a photo index of 3-3.8 with varying iron-K features in different Xray states. The simultaneous Subaru and X-ray light curves in the oscillation phase indicate that infrared flares occur after the X-ray dip with variable time delay. This result strongly suggests that the disc transition from State C to State A triggers the ejection of jet, which eventually produces infrared/radio flares by internal shock.
