4 January 2008 --

Week 622 results (2007 December 28 - 2008 January 3)

  • Mkn 421 - about 25 mCrab
  • Cir X-1 - below 20 mCrab
  • X1553-542 - ~25 mCrab (based on relatively noisy data); see also ATel No. 1345
  • X1630-472 - ~130 mCrab; see also ATel No. 1348
  • H1743-322 - the data show a number of high intensities; however, these could all be strongly affected by solar contamination; in the opinion of the reviewer (AML) it is premature to conclude that this source is in outburst (cf. ATel No. 1348). Note that this is much different from the case of X1630-472, where the results do NOT look noisy like the product of contamination.
