*************************************************
*************************************************
** Covered period : 2009/04/20 - 2009/04/26 **
*************************************************
*************************************************


Highlights:

  • PKS 1510-089 was very strong during this week, it shows a flux higher than 12 times the average flux of previous months. Atel #2033 was issued.
  • 3C273 was quite bright and it was detected in almost days reaching flux of 2.1+/-0.5e-6 ph/cm^2/s.
  • PKS 1502+106 still bright reaching a flux of 2.0+/-0.4e-6 ph/cm^2/s in the daily time scale.
  • 3C454.3 was quite bright and it was detected in almost days reaching flux of 1.9+/-0.4e-6 ph/cm^2/s.
  • B2 1502+31 high activity state, it was reaching flux of 1.9+/-0.7e-6 ph/cm^2/s. Atel #2026 was issued.

Note. All the flux reported above are by the ASP analysis and should be considered preliminary and cannot be used for publication, however they are indicative of the flux range and the current status of a source.

*************************************************
*************************************************
** Covered period : 2009/03/30 - 2009/04/05 **
*************************************************
*************************************************

Highlights:

  • PKS 1510-089 very strong also during this week (1.4E-6 to 2.6E-6 ph/cm^2/s).
  • PKS 1502+106 still bright (around or somewhat below 1E-6 ph/cm^2/s during the week).
  • PKS 1454-354 shown a mildly increasing weekly trend in the last 3 weeks (the daily flux of 1E-6 ph/cm^2/s has been reached only on April.04).
  • New source, very preliminary associated with PKS 0402-362 (z=1.417).
  • PMN J0948+0022 detected for the first time on a daily scale (only on Apr.01).
