Public INTEGRAL Observations of the Supernova SN2014J
=====================================================

On 31 January 2014, INTEGRAL has started Target of Opportunity
observations on the recently discovered type Ia SN2014J in M82 (ATel #5835).
At a distance of about 3.5 Mpc, this is the closest type-Ia SN
discovered in the past 4 decades. This SN event is unique, and
INTEGRAL is the only observatory currently capable of doing
high-resolution gamma-ray spectroscopy, which may help to constrain
the models of the SN explosion. Therefore, INTEGRAL will observe this
SN almost exclusively for the next months. If successful, these
observations are expected to constitute a reference in SNIa science
for years to come.

Part of total observing time on SN2014J will be composed of 2 Msec
from an approved INTEGRAL Target of Opportunity program (PI: Jordi
Isern, ICE-CSIC/IEEC, Spain). The Early data of this observations,
performed in revolution 1381 and 1382 will be publicly available in
the ISDC archive, populated about one month after the observation is
performed (i.e. as CONS data).

The second part of the observation will be immediately accessible to
all users already in their near real time version (NRT data). An
additional, comparable, amount of INTEGRAL observing time has been
awarded by the Project Scientist, on request by the INTEGRAL SN
community, to maximise the scientific returns and will also be
publicly available.

The first INTEGRAL observation of SN2014J has been done in Revolution
1380, and the associated data are publicly available.
See the page:
http://www.isdc.unige.ch/integral/archive#DataRelease
for instructions on how to retrieve public data.

The strategy of further Target of Opportunity observations depends on
the evolution of this SN. 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 short-term plan is available on the ISOC scheduling page at:
