12th Announcement of Opportunity (AO-12): preliminary statistics
11 April 2014 The deadline for the submission of proposals for AO-12 open time observations was on 4 April 2014, and all proposals are in the ISOC database. Below are some preliminary statistics on the proposals that have been received.
Total number of proposals
The total number of proposals received is 77. The total observing time requested is about 107 Msec (for all types of observation, i.e., fixed time, normal time, and ToO). Here, 10% of the requested total ToO time has been taken into account. Given that up to about 22 Msec of observing time (for new observing proposals) will be available for the AO-12 observing programme (12 months duration starting on 1 January 2015), this corresponds to an oversubscription in time by a factor of 4.8.
The non-ToO proposals are requesting data rights for 523 sources in total. 12 proposals requested coordinated XMM-Newton time; a similar amount requested coordinated Swift time.
Proposals per category
In the following table we give the breakdown of number of proposals as a function of the proposal category. Note that the numbers on requested observing times do include ToO proposals, but it has been assumed here, that a typical ToO proposal requests about 10% of its total observing time as entered into PGT from all the candidate sources included in a ToO proposal.

At the end of May, the Time Allocation Committee will peer review all proposals and recommend the AO-12 observing programme to ESA.
INTEGRAL detects radio-active Co56 from SN2014J
21 March 2014 INTEGRAL's observations of SN2014J (proposal 1170001: public data, and proposal 1170002, PI: R. Sunyaev), which took place between March 3 and 19, reveal the 847 keV line due to the radio-active decay of Co56. INTEGRAL will continue to observe SN2014J for at least another 5 weeks till the end of April. For more detail see the announcement in ATel #5992.
INTEGRAL AO-12 proposal deadline approaching & Source Grouping Tool
21 March 2014 The deadline for AO-12 observing proposals is approaching. We encourage previous second round data rights proposers to submit for AO-12 regular observing proposals for their favourite targets (or science) since amalgamation will be made more flexible. In order to help creating sensible observing proposals for astronomers interested in groups of similar targets, we have created a tool that for a list of target positions will propose a grouping of these targets into a smaller number of observations, such that all targets are covered. For details on this tool, its installation and use, please see the SGT page.
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.
More information can be found in the latest Long-Term Plan.
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.
