INTEGRAL Latest News
Solar flare is affecting INTEGRAL operations
3 March 2014 The INTEGRAL operations were affected by a strong X-class solar flare, which forced the OMC to be put in safe mode around UT 11:00 on 25th February, and later JEM-X around UT 10:00 on 28th February. OMC and JEM-X science operations resumed at the beginning of the subsequent revolution (1390), around UT 05:00 on March 2. SPI and IBIS were operating nominally during that period, but their data may be affected by a high particle background.
Continued INTEGRAL observations of SN2014J
27 February 2014 Following calibration observations of the Crab, INTEGRAL is currently doing further public observations of SN2014J from Revolution 1388 to 1392 under program 1170001. These will be followed by four revolutions with SN observations falling under the Russian share (PI: Sunyaev) from Revolution 1393 to 1396 under program 1170002. Further observations under the approved ToO program (PI: Isern), proposal 1140011, will follow in Revolutions 1397 to 1402. The NRT data of the observations under programs 1170002 and 1140011 will not be public. However, for the benefit of the community, the consolidated data will be made available to the public. These dara are typically available about a month after the observations have been done from the ISDC archive via http://www.isdc.unige.ch/integral/archive, Further public observations of SN2014J are currently forseen for Revolutions 1402 to 1407. All of these observations will be interspersed with short monitoring programs.

INTEGRAL AO-12 Call for Observing Proposals is open!
24 February 2014 Today, the Director of Science and Robotic Exploration (Prof. Alvaro Giménez) has released the 12th Announcement of Opportunity for observing proposals with INTEGRAL.
This announcement solicits proposals for observations to be carried out from January 2015 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 4 April 2014, 14:00 CEST.
We would like you to be aware that ESA has implemented the following important changes to AO-12:
- ESA will revert from this year to a single, annual AO for observing proposals, and so there will be no 2nd call for data rights proposals anymore. ISOC encourages previous 2nd round data rights proposers to submit for AO-12 regular observing proposals for their favourite targets (or science). ISOC will make amalgamation more flexible (i.e., with less restrictions), and will facilitate in helping previous data rights proposers.
- Data or science rights to the targets or science in the field of view (FOV) of the instruments proposed by the PIs in response to AO-12 will be allocated to these PIs with the usual 1-year proprietary period, if their proposal is accepted by the TAC. If the PI is from a country other than the Russian Federation, the rest of the field will be made public. If the PI is from the Russian Federation the rest of the field will be open only to all Russian Federation scientists currently working at Russian Federation scientific institutes. ISOC and ISDC will take measures to ensure that the approved 1-year proprietary nature are respected. For further details we refer to the AO-12 documentation.
- New also for AO-12 is the opportunity to propose for coordinated observations with NASA's Swift satellite, in addition to the already existing programme with XMM-Newton.
More information can be found on the AO-12 page.
Ongoing INTEGRAL observations of SN2014J
4 February 2014 After a public observation in Revolution 1380 under program 1170001, INTEGRAL is now doing observations up to Revolution 1386 under an approved ToO program (PI: Isern), proposal 1140011 (see our short-term scheduling information). The NRT data will not be public. However, for the benefit of the community, the PI has agreed to make the processed data (i.e., CONS data) immediately available to the public at large. The CONS data are typically available about a month after the observations have been done.
The CONS data will be accessible from the archive at the ISDC using the browse interface: http://www.isdc.unige.ch/integral/archive. Note that, as usual, NRT data of public observations will be accessible using the instructions at the page: http://www.isdc.unige.ch/integral/archive#DataRelease.
INTEGRAL Target of Opportunity observations on SN2014J in M82
30 January 2014 A supernova was detected in M82 on January 21, 2014 at the UCL Observatory (CBET #3792). Originally it was designated PSN J09554214+6940260; it has been identified as a type Ia SN (ATel #5786) and is referred to as SN2014J (CBET #3792). At the distance of about 3.5 Mpc, this is the closest type-Ia SN discovered in the past 4 decades.

This SN event is very unique and INTEGRAL is the only observatory currently capable of doing high-resolution gamma-ray spectroscopy. Therefore, INTEGRAL will observe this SN almost exclusively for the next months. These observations will hopefully constitute a reference in SNIa science, and thus an important scientific legacy for years to come.
Part of total observing time on SN2014J will be composed of 2 Ms of a TAC-approved ToO (PI: Isern). An additional, comparable, amount of observing time will be made available to maximise the scientific returns. The important change in our planning due to this exceptional event implies that various previously foreseen programmes will not be carried out. ISOC will do everything it can to minimise the consequences this will have on the accepted programme.
The first INTEGRAL observation will be done in Revolution 1380, which starts already on UT January 31 07:08. The data obtained during this Revolution will be made publicly available. Further ToO observations will be planned and the observing strategy depend on the evolution of this SN. An announcement has been made in ATel #5835.
Note that the observations in Revolution 1380-1382 are done with the nominal 5x5 dither pattern with the pointing centre offset by 2 degrees, to avoid the Solar Aspect Angle observing constraint.
