The INTErnational Gamma-Ray Astrophysics Laboratory
was launched in October 2002 aboard a Russian Proton rocket, and is
providing a new insight into the most violent and exotic objects of the
Universe, such as neutron stars, active galactic nuclei and
supernovae. INTEGRAL is also helping us to understand processes such as
the formation of new chemical elements and the mysterious gamma-ray
bursts, the most energetic phenomena in the Universe. Environments of
extreme temperature and density, near the event-horizons of black holes,
are a major topic of study with INTEGRAL.
These studies are possible thanks to INTEGRAL's combination of fine
spectroscopy and imaging of gamma-ray emissions in the energy range of 15 keV
to 10 MeV (using the SPI and IBIS instruments) and concurrent monitoring in
the X-ray band (4-35 keV) using JEM-X, and in the optical (500-600 nm) band,
using the OMC.
A project of the European Space Agency
INTEGRAL, serves an international Guest Observer
community. Participation by U.S. astronomers was
supported by a Guest Observer Facility (GOF) at the NASA/Goddard Space
Flight Center (GSFC) from the mission start until October 2010. Since
then, the mirroring of the European INTEGRAL Public Data Archive into
the HEASARC has been continued by the HEASARC.

16th INTEGRAL Announcement of Opportunity (06 Mar 2018)
ESA invites you to submit proposals to the International Gamma-ray
Astrophysics Laboratory (INTEGRAL) 16th "Announcement of
Opportunity" (AO-16) call for proposals, for observations to be
performed during 2019. As previously, ESA also provides the
opportunity to propose for coordinated observations with XMM-Newton,
NuSTAR, and/or Swift with a total of 300 ks, 100 ks, and 150 ks,
respectively, of their available time. Documentation, proposal
submission and support software for this Announcement are being made
available via the ESA
INTEGRAL website. The deadline for proposal submission is
Friday, April 13, 2018, 14:00 CEST.
INTEGRAL Mission Extended Through 2019 (18 Dec 2017)
The ESA Science Programme Committee (SPC) has approved extending the INTEGRAL mission by one year through 31 December 2019.
A proposal to extend INTEGRAL through 2020 will be presented at the next meeting of the SPC in February 2018.
INTEGRAL AO-15 General Program Approved (8 Jun 2017)
The INTEGRAL AO-15 General Program, as recommended by
the Time Allocation Committee (TAC) and approved by ESA's Director of
Science (Prof. Alvaro Giménez), has been
released and the observers have been informed.

INTEGRAL Public Data Archive Status
The HEASARC mirror to the INTEGRAL Public Data Archive now contains data through the May 10, 2018
public data release (revolution 1803). It also contains all data from recent observations for which
the PI has allowed the data to be made public earlier than the 1 year proprietary period.
The next scheduled public data release is May 25, 2018.
