    Abstract

    We investigated serendipitous INTEGRAL observations carried out at thetime of the LIGO/Virgo burst candidate G298048. The satellite was covering a fraction of the probability of the LIGO-Virgo localization. The best sensitivity depends on the source location. We investigated the SPI-ACS light curves between -30 and +30 s from the trigger time (2017-08-17 12:41:04 UTC, T0) on temporal scales from 0.1 to 100s. In the SPI-ACS data, we detect a short and relatively weak transient with S/N of at T0, with an S/N larger than 3. coincident with the GBM trigger (Connaughton 2017, GCN 21506). Further analysis is ongoing, and will be reported in the coming circulars.
