General Description

• These OBs intend to obtain 8.8, 9.8, 11.4 and 12.4 micron
  low resolution VISIR spectra of two new FU Orionis stars:
  ISO-Cha I 192 and Car I No. 136.
  
  FUor variables alternate quiescent (or T Tauri) states with periods of
  extremely high activity (FUor eruption). During the outburst phase,
  each lasting for up to 100 yr, FUors exhibit large optical outbursts
  of as much as 5 mag.
  
  ISO-Cha I 192 and Car I No. 136 have been recently detected and
  as for May 2003 they had Ks-magnitudes of 10.61 and 13.45, respectively.
  Although we can not guarantee the brightness of these targets at the present
  time, we expect them to have Ks-magnitudes close to the ones reported for May 2003.
  
  For ISO-Cha I 192 the finding chart provided is the 2MASS Ks image corresponding
  to Jan-May 2000 when the star had Ks = 11.02. There should be two stars
  in the VISIR field. ISO-Cha I 192 is the one to the NE.
  
  For Car I No. 136 the finding chart provided is a Ks image obtained
  with PANIC at the Magellan Clay Las Campanas Telescope in May 2003,
  when the star had Ks = 13.45. Car I No. 136 was not detected on
  the 2MASS image taken in Jan 2000 and thus it must have been fainter
  than Ks = 14.5 at that time. There should be two stars in the VISIR field.
  Car I No. 136 is the one to the SE.
