Hurley (UC Berkeley Space Sciences Laboratory) and D. Gotz (CEA/SAP, Saclay), on behalf of larger teams, report: In view of the resurgence of activity of SGR1900+14 (GCN 4923, 4933), we have called two ToO observations of this source. INTEGRAL will observe it almost continuously between April 1 13:32 and April 3 06:21. XMM will observe it for 25 ksec starting April 1 15:00. Observations at other wavelengths, particularly the radio and infrared, are encouraged. Observers should consult the INTEGRAL and XMM websites for any last-minute schedule changes.
