XMM-Newton Observations of GRB020322 - XMM-Newton
XMM-Newton Observations of GRB020322
- On March 22, 2002, the XMM-Newton SOC received a Target of Opportunity notification after the BeppoSAX detection of GRB020322.
- This GRB was immediately approved by the XMM-Newton SOC for ToO observation. The observation was started on 2002-03-22T18:18:00Z under ObsId=0128530801 during XMM-Newton's revolution number 0418.
- The pointing coordinates were RA = 18:00:49.4 and Dec = +81:06:10.8 (Gandolfi et al.)
- A source was shortly identified in EPIC, ~20 arcsec off the reported coordinates, well away from inter-CCD gaps.
- On Mar 22, 2002 20:46, GCN1293 was issued, reporting a first estimate of the coordinates of that bright source and its count rate.
- The images and light curves presented here are based on a preliminary processing without the re-constituted XMM-Newton Attitude History File. Therefore, the positions quoted are subject to an uncertainty of 4 arcsec.
- The Observation Data File (ODF) for GRB020322 was re-generated on 03-Apr-2003 in order to eliminate information contained in the old ODF (with id: 0110980301) belonging to the previous observation. This was preventing the nominal Pipeline processing of the data.
The new ODF (with id: 0128530801) now contains only the GRB020322 data and has been successfully processed by the Pipeline.
The new ODF is available here as 0128530801.tar.gz.
- The Pipeline Products are also available in the ftp area. Details of the Pipeline process can be found here

|The image is centered at the "b" source in GCN1296 from Bloom et al. which has been suggested to be the optical after-glow of GRB020322 (GCN1298).|
|Full OM image in sky coordinates.|
|The extended blob and ring-like features near the center of the image are due to stray light.|

Quick Look Analysis
Light curves for the two brightest pn sources within 2arcmin of the reported BeppoSax position (labelled as #1 and #2 in the image above). Only pixels within 30arcsec of the sources peak have been considered for the light curves.
|The total count rate from the brightest source decreased by a factor ~2 in ~12ks.|
