The Fermi/LAT Collaboration is organizing a multiwavelength campaign to monitor the quasar PMN J0948+0022, already detected at gamma-rays by LAT (Bright Source List; Bright AGN List; plus a dedicated LAT paper accepted for the publication on ApJ - see preprint).
The period will last 3 months, starting at the end of March, with the beginning of Swift observations. The campaign will end on 5 July 2009.
Present coverage:
- Gamma-rays: Fermi/LAT
- X-rays: Swift/XRT
- NIR/Optical/UV:
- Swift/UVOT (VBU/UVW1-UVM2-UVW2)
- ATOM (BVRI, Wagner)
- INAOEP, Mexico (NIR, Carrasco)
- Radio:
- OVRO 15 GHz (daily monitoring, Readhead et al.)
- Effelsberg (cm/mm, Fuhrmann et al.)
- RATAN-600 (1-22 GHz, Kovalev)
- MOJAVE (Lister)
- e-VLBI (Giroletti)
- Metsahovi (37 GHz, Lahteenmaki et al.)
Swift schedule:
- 1st: 26 March 2009
- 2nd: 15 April 2009
- 3rd: 5 May 2009
- 4th: 10 May 2009

Data format and deadline to participate to the paper in preparation:
Data format:
- Time: MJD
- Fluxes (nuFnu): erg/cm2/s (or Jy*Hz, if easier)
- Fluxes should be already corrected and dereddened (ground based observatories should correct also for the extinction due to the airmass). Use as reference AV=0.277 and the extinction laws of Cardelli et al. (1989).
- Include also the observed magnitudes (for NIR/optical/UV data).
Deadline to send data: 31 July 2009
