Proceedings 10th INTEGRAL Workshop available

INTEGRAL AO-13 Call for Observing Proposals is open!

9 March 2015 Today, the Director of Science and Robotic Exploration (Prof. Alvaro Giménez Cañete) has released the 13th Announcement of Opportunity for observing proposals with INTEGRAL.

This announcement solicits proposals for observations to be carried out from January 2016 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 17 April 2015, 14:00 CEST.

We would like to draw your attention to the following points:

  • Following a recommendation by the IUG it is possible to submit Key Programme proposals with observations spanning two AO cycles of observation.
  • To ensure a safe disposal in 2029, a series of dedicated manoeuvres modifying the orbit of INTEGRAL were executed in January and February, this year. The new orbit has a nominal duration of about 64 hours, compared to the old one, which lasted around 72 hours. Consequently, the available observing time per revolution is now approximately 170 ks, compared to 210 ks before the orbit change was implemented.
  • 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. Because of the overall reduced manpower in INTEGRAL operations, the use of non-standard patterns is now strongly discouraged. Hence, starting in AO-13, custom patterns will be considered only for the highest, A-grade, proposals, and their scheduling will be done on a best effort basis.
  • ESA continues to provide the opportunity to propose for coordinated observations with XMM-Newton and/or NASA's Swift satellite. A total of 300 ks of XMM-Newton observing time and a total of 150 ks of Swift observing time is available for these coordinated observations.
  • Finally, we would like to remind you that there is no second call for proposals requesting data rights anymore (so-called data rights proposals). Therefore, we strongly encourage you to submit any data rights proposals as observing time proposals in the coming and future announcements of opportunity; amalgamation has been made more flexible.

INTEGRAL TOO observations of SAX J1748.8-2021 in NGC 6440

20 January 2015 After the INTEGRAL detection of renewed activity at hard X-rays from a transient within the Globular Cluster NGC 6440 (ATel #7098), the source was identified with Swift/XRT to be most probably the accreting millisecond X-ray pulsar SAX J1748.8-2021 (ATel #7106). In response to a ToO request raised from the community, the Project Scientist has approved a public ToO observation of 100 ks which will begin at the start of revolution 1511 on 23 Feb 2015 at 12:20:46.

INTEGRAL back in business

13 February 2015 The fourth, and last, manoeuvre on 12 February of the INTEGRAL de-orbiting campaign was completed successfully. INTEGRAL is now in its final revised orbit. Science observations will start again on 15 February (Revolution 1508).

Where is INTEGRAL?

12 February 2015 ESA operations has provided widgets which are fed with the latest orbital tracks for ESA missions, or missions with significant ESA participation. Follow the link to `Track ESA Missions' and click on the blue name icon "Integral" to find out where INTEGRAL is.

Successful manoeuvre on 24 January.

27 January 2015 The second manoeuvre on 24 January, the largest of the 4 disposal manoeuvres, of the INTEGRAL de-orbiting campaign was successful. All operations could be executed as planned with no deviations from the timeline. As ever the satellite performed flawlessly. INTEGRAL is now back in science mode. The next, smaller, manoeuvre is planned for 4th February; see the News item on 9 January 2015. Follow ESA's Rocket Science blog for a detailed account.
