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

Lars Hansson

 

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:

  • ESA provides the opportunity to propose for coordinated observations with XMM-Newton, NASA's NuSTAR telescope and/or NASA's Swift satellite with a total of 300 ks, 100 ks and 150 ks, respectively, of their available time. Note that through an agreement with ESA, the Fermi project of NASA offers the possibility to obtain observing time with INTEGRAL through a single proposal to NASA via the Fermi AO.
  • Data or science rights to the targets or science in the field of view (FOV) of the instruments will be allocated to PIs of accepted proposals with the usual 1-year proprietary period. If the PI is from a country other than the Russian Federation, the rest of the field will be made public immediately. Proposals where the PI is from the Russian Federation follow a similar kind of policy, except that the rest of the field will be made public only through the consolidated data programme. The Russian Federation scientists currently working at Russian Federation scientific institutes still have exceptional access to the near-real time data of the rest of the field.
  • The INTEGRAL Project has signed a Memorandum of Understanding (MoU) with the LIGO/Virgo consortium to participate to the electro-magnetic follow-up campaign of GW signals until 1 June 2017; a renewal will be discussed in due time.
  • Observations with non-standard, custom patterns, such as the GPS and Galactic scans, generally reduce scheduling efficiency, and increase workload for both the ISOC and the Mission Operations Centre. The use of non-standard patterns is now strongly discouraged. Hence custom patterns will be considered only for the highest, A-grade, proposals, and their scheduling will be done on a best effort basis.
  • Following a recommendation by the IUG it is possible to submit Key Programme proposals with observations spanning two AO cycles of observations.
  • Finally, we would like to remind you that there is no second call for proposals requesting data rights (so-called data rights proposals). Therefore, we strongly encourage you to submit any data rights proposals as observing time proposals in this and future AOs; amalgamation has been made more flexible.

Neil Gehrels: 3 October 1952 - 6 February 2017

INTEGRAL has lost a great Mission Scientist

Neil Gehrels

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.
