AO-15 DEADLINE DRAWING CLOSE
28 March 2017 The deadline for proposals in AO-15 is drawing close (31 March 2017, 14:00 CEST). To aid proposers writing (new) proposals, we have compiled a checklist from the documentation.
INTEGRAL TOO OBSERVATIONS of IceCube-170321A
22 March 2017 On UT 21 March 07:32:21 IceCube detected a track-like, very-high-energy neutrino event, with a high probability of being of astrophysical origin, IceCube-170321A. Follow-up observations have been initiated on ground and space-based observatories to help to identify a possible astrophysical source for the event. This triggered an accepted AO-14 Target-of-Opportunity proposal (PI: M. Santander). INTEGRAL observations will start today at UT 15:10:29 for a duration of 45 ksec. The data will be public.
Update 23 March Unfortunately, the observations at the start of Revolution 1796 were affected by a malfunction of the IBIS Veto system. This required a partial restart of the instrument. IBIS was back in science mode from UT 16:37:52 on March 22.
Lars Hansson: 11 October 1942 - 15 March 2017
20 March 2017 Lars Hansson, former INTEGRAL Science Operations Manager passed away on Wednesday 15 March 2017.
Lars' career at ESA covered a range of missions among them COS-B, EXOSAT, Hipparcos, ISO and INTEGRAL. He retired end of 2006 as INTEGRAL Science Operations manager, having seen the INTEGRAL SOC through the development and the early mission phase. He and his wife Åsa then shared their time between Spain and Sweden.
The ISOC remembers Lars as a positive, forward driving person always supportive of the people in his team, a person we will miss.
INTEGRAL AO-15 CALL FOR OBSERVING PROPOSALS IS OPEN!
20 February 2017 Today, the Director of Science (Prof. Alvaro Giménez Cañete) has released the 15th Announcement of Opportunity (AO-15) for observing proposals with INTEGRAL.
This announcement solicits proposals for observations to be carried out from January 2018 for a period of 12 months. Proposers from all over the world are welcome to participate. All proposals will be subject to an independent peer review by the INTEGRAL Time Allocation Committee (TAC). The deadline for proposal submission is Friday 31 March 2017, 14:00 CEST.
We would like to draw your attention to the following points:
Neil Gehrels: 3 October 1952 - 6 February 2017
INTEGRAL has lost a great Mission Scientist
07 February 2017 Neil Gehrels passed away yesterday morning. Neil was PI of Swift and Project Scientist for WFIRST, and had a major role in many other high energy astrophysics missions including CGRO, INTEGRAL and Fermi. He was also President of IAU Commission D.1 on Gravitational Wave Astrophysics.
His ideas, scientific advice, contributions and critical reviews through all phases of the INTEGRAL mission development, were of great value and importance.
Neil had been battling pancreatic cancer. His health declined precipitously over the past several weeks. We will miss Neil; a very kind and very dear colleague and a great high-energy astrophysicist.

INTEGRAL fully recovered again
23 January 2017 On 21 January 15:30Z, IBIS was enabled in the observation timeline again and INTEGRAL returned to normal operations, with SPI still being annealed.
INTEGRAL in ESAM, recovery ongoing
18 January 2017 This morning at 05:41Z INTEGRAL has entered the Emergency Sun Acquisition Mode (ESAM) for the sixth time since launch. All active instruments went to safe mode, SPI was already inactive due to the ongoing annealing. The ESAM was triggered by diverging reaction wheel speeds during a slew. While the investigation of the root cause is ongoing, recovery operations are underway. Scientific operations will probably be picked up again at the start of the next revolution (1773) on 20 January.
Update 20 January Unfortunately, on reactivation of the instruments this morning it was found that a full deactivation and reactivation of IBIS will be required, delaying science data taking accordingly.
ISOC AO-14 observations underway and preparations for AO-15
9 January 2017 ISOC wishes you a healthy and successful 2017. The AO-14 cycle of observations started on January 1st and will last 12 months, see the INTEGRAL target lists and sky maps for details as well as the Long-Term Plan.
ISOC is preparing the next call for proposals requesting INTEGRAL observing time. The AO-15 release will be already on 20 February, with a deadline on 31 March 2017. The AO-15 cycle of observations is foreseen to begin on 1 January 2018 and has the usual duration of 12 months.
