| INTEGRAL Announcement of Opportunity for Key Programme Observing Proposals for the AO-5 Cycle of Observations |
| Dear Colleague,
I am pleased to invite you to the first "Announcement of Opportunity for Key Programme Proposals" by submitting key programme proposals for observations to be performed with the International Gamma-ray Astrophysics Laboratory (INTEGRAL) satellite. |

| Gamma Ray Emission from Cassiopeia A |
| Supernovae and their remnants are the main galactic nucleosynthesis sites. Few radioactive isotopes are accessible to gamma-ray astronomy for probing these stellar explosions. Among them, 44Ti is a key isotope for the investigation of the inner regions of supernovae and their young remnants. |

| Detecting Gamma-ray Bursts outside INTEGRAL's Field of View |
| Making use of the double detector layer design of the IBIS instrument on-board INTEGRAL, a team of European astronomers have proved it possible to observe powerful gamma-ray bursts even if they fall outside the telescope's field of view. |

|
| Powerful Emission from Anomalous X-ray Pulsars |
| INTEGRAL has detected surprisingly powerful X-ray and gamma ray emission from a special class of neutron star. This discovery makes them the most magnetically active bodies in the Universe. |

|
| INTEGRAL 4th Announcement of Opportunity |
| The Director of the Scientific Programme, Prof. David Southwood, has released the 4th Announcement of Opportunity (AO-4) for observing proposals with INTEGRAL. |
| Date: 17 Mar 2006 |

|
| INTEGRAL Mission Extension Approved |
| ESA's Science Programme Committee has extended operations of the highly successful astronomical observatory INTEGRAL until 16 December 2010. |

| Highlights from INTEGRAL |
| The International Gamma-Ray Astrophysics Laboratory INTEGRAL was launched on 17 October 2002 at 04:41 UTC from Baikonur Cosmodrome (Kazakhstan) and is nearing its milestone of 3 years of science operations.

| The Galactic Centre Region |
| In an article to be published in the Astrophysical Journal, Bélanger et al. present the results of a detailed analysis of approximately 1900 hours of observations of the galactic centre, obtained with Integral since the launch of the spacecraft in October 2002. |
| Date: 14 Sep 2005 |

|
| INTEGRAL in the Journals |
| A number of interesting papers have recently been published based on data gathered by INTEGRAL - ESA's gamma-ray observatory. They cover a range of observations covering all the capabilities of the spacecraft. |

| INTEGRAL OMC Catches A GRB |
| Before June 26 no Gamma-Ray Burst (GRB) had been been observed in the field of view of the Optical Monitoring Camera (OMC) onboard INTEGRAL. Despite over two and half years in orbit this result is not too surprising given the much field of view of the OMC is just 5° by 5° (0.06 % of the whole sky)

|
| INTEGRAL Observations of the Galactic Centre Region |
| Integral continues to observe the X-ray and gamma-ray emission from the galactic centre region. These observations at the high-energy end of the electromagnetic spectrum contribute to our knowledge of the physical processes at play and the type of objects residing at the centre of our Milky Way. |

| Summary of Internal INTEGRAL Science Workshop |
| On the initiative of J.-P. Roques and C. Winkler, an Internal INTEGRAL Science Workshop was held at ESTEC from 18 to 21 January. The purpose was not only to present the latest scientific results (after the fifth INTEGRAL workshop in Munich, 2004), but also to provide a forum for discussion on instrument (cross-)calibration, software performance and other issues. |

| INTEGRAL TOO observation of V0332+53 in outburst |
| The High-Mass X-ray Binary V 0332+53 (EXO 0331+530), currently undergoing a dramatic outburst, was a Target of Opportunity (TOO) for an INTEGRAL observation on 6-10 January 2005. The source was observed as soon as allowed by visibility constraints on 6 January in staring mode and then in the hexagonal dithering mode for a total of about 110 ksec. |

| Viewing the High-Energy Universe |
| ESA's two high-energy astrophysical observatories have produced new views on some of the extreme events at work in the Universe. INTEGRAL observations of the galactic plane reveal some indications on the distribution of matter and antimatter, while XMM-Newton has observed an X-ray afterglow to a supernova explosion in NGC 2403, just 11 million light years away. |

| First INTEGRAL Data Analysis Workshop |
| The first INTEGRAL Data Analysis Workshop brought together PhD students as well as experienced researchers all wanting to learn more about INTEGRAL and how best to analyse the data from ESA's gamma-ray observatory. The Workshop was organized by the INTEGRAL Science Data Centre (ISDC) on 5-9 October 2004. It was split into two parts. |

| INTEGRAL Announcement of Opportunity (AO-3) |
The deadline for submission has passed.
The programme will be released in due course.
Dear Colleague,
I am very pleased to invite you to respond to the 3rd "Announcement of Opportunity" by submitting proposals for observations to be performed with the International Gamma-ray Astrophysics Laboratory (INTEGRAL) satellite.

| ESA's Integral detects closest cosmic gamma-ray burst |
| gamma-ray burst detected by ESA's Integral gamma-ray observatory on 3 December 2003 has been thoroughly studied for months by an armada of space and ground-based observatories. Astronomers have now concluded that this event, called GRB 031203, is the closest cosmic gamma-ray burst on record, but also the faintest. This also suggests that an entire population of sub-energetic gamma-ray bursts has so far gone unnoticed. |
