Snow-cleaning for the INTEGRAL Mission

13 November 2015 With a winter storm coming in and temperature not solid under 0 degrees, a layer of snow builds-up at the ESTRACK KIR-1 antenna at Salmijärvi, Kiruna. The M&O team is using the new acquired "Cherry Picker" to manually clean the reflector surface to ensure INTEGRAL will not miss a bit of its valuable scientific data.

Happy birthday INTEGRAL!

17 October 2015 Thirteen years ago, on 17 October 2002 at 6:41 CEST, the INTEGRAL observatory was launched from Baikonur. Today, it still remains in excellent health and continues to observe the gamma-ray and X-ray sky.

INTEGRAL TOO observations of the  BEXRB TRANSIENT V 0332+53 RETURNING TO quiescence

5 October 2015 The Be X-ray binary transient V 0332+53, in outburst since mid-June, has recently entered the sub-critical regime. INTEGRAL TOO observations of this source in revolution 1596 (2015-10-07 14:30:05 to 2015-10-09 17:28:22) will attempt to measure the system cyclotron line energy in the lowest observable state.


27 July 2015 The accreting ms pulsar IGR J00291+5934 has been found to be active in the optical, by Swift and by MAXI. Concurrent ToO observations have been requested and approved for INTEGRAL revolution 1569 (2015-07-27 17:44:06 to 2015-07-29 20:56:46) and within XMM-Newton revolution 2863 (2015-07-28 11:48:19 to 2015-07-29 11:51:02).

INTEGRAL TOO observations of the BHC GS 1354-645

23 July 2015 The BHC GS 1354-645 has been in outburst since the end of June 2015 and seems to have reached its peak intensity at hard X-rays. An INTEGRAL ToO observation has been approved at the end of revolution 1572 as part of a multi-wavelength campaign, including ALMA, ATCA and possibly other observatories.

INTEGRAL TOO observations of a bright BeXRB transient: V 0332+53

9 July 2015 The Be X-ray binary transient V 0332+53 entered into outburst again in mid June after several years of quiescence and has by now reached almost 600 mCrab in the hard X-ray band. An INTEGRAL ToO observation has been accepted in the first part of revolution 1565 in order to study the source near the peak of the outburst. The source evolution can be followed, e.g., via the link from the BeXRB Monitor page.

Update 24 July 2015 As the source is still rising in flux, another ToO observation of V 0332+53 has been accepted for revolution 1569.

Update 27 July 2015 Due to the accepted TOO of IGR J00291+5934 and still rising flux, the observations of V 0332+53 have been moved to revolution 1570.

INTEGRAL AO-13 General Programme approved

9 July 2015 The INTEGRAL AO-13 General Programme, as recommended by the Time Allocation Committee (TAC) and approved by ESA's Director of Science and Robotic Exploration (Prof. Alvaro Giménez), has been released and the observers have been informed.

Astronomers use cosmic gravity to create a 'black-hole-scope'

6 July 2015 INTEGRAL, Fermi and Swift have used the magnifying power of a cosmic lens to explore the inner regions of a supermassive black hole in PKS 1820-311. The findings by A. Neronov et al. have been published online in Nature Physics today.
