[vsnet-history 856] SN 1993J (Filippenko)

Subject: SN 1993J update

   4-28-93
SN 1993J junkies:
   The supernova is definitely beginning to fade! It is very important
to closely monitor the brightness in all possible bands; it could fall
rapidly to the late-time tail, or it might proceed more slowly (staying
on the "plateau" for a while longer). We really don't know how much
of a hydrogen envelope the star had at the time of the explosion.

   Also of great importance are low-dispersion spectra during the upcoming
bright run. As was the case last month, many large telescopes will NOT
be equipped with low-dispersion optical spectrographs; thus, much of the
burden will fall on the smaller telescopes. I urge you to get data as
frequently (and over as large a wavelength range) as possible.

   Of course, efforts to get infrared photometry and spectroscopy should
continue. We ultimately need to derive a bolometric light curve of the
supernova (or as close to bolometric as possible). This won't be possible
without the infrared data.

   Below are some notes from others, including a useful reminder from
Roberta Humphreys.

   Cheers,

   Alex Filippenko

  Hi Alex,

   Your points about the reddening problem in M81 are valid except that the
  2200A feature cannot be used to set a limit or to define the extinction
  in the visual. It and the UV extinction relation are highly variable in
  our galaxy and the LMC and SMC have very different relations from the 
  what we call the galactic UV extinction relation.

    Several years ago while working with UV spectra of some hot stars in
  M31 and M33 I found that the galactic UV extinction relation way over 
  corrected the 2200A feature producing a bump in the energy distribution.
  The LMC relation worked much better. In subsequent work by Phil Massey
  both of these galaxies he has shown that a UV extinction laew like the 
  LMC is the correct one for both M31 and M33! We don't have any idea
  what is appropriate for M81.

    While the visual/near-IR extinction extinction "law" appears to be 
  very uniform in our galaxy and apparently in others not so for the UV.

    There are several stars even in our galaxy with high visual extinction
  and NO 2200 A feature. Not only is this strange but also can be very 
  misleading without additional information.

    Regards, Roberta

SN 1993J in NGC 3031

S. D. Van Dyk & K. W. Weiler, Naval Research Laboratory; R. A.
Sramek & M. P. Rupen, National Radio Astronomy Observatory;
and N. Panagia, Space Telescope Science Institute, report that new
observations of SN 1993J made on 1993 April 22.47 UT with the
Very Large Array in `B' configuration show that the source
currently has a flux density at 1.3-cm wavelength (22.5 GHz) of
39.94 +/- 0.53 mJy; the radio light curve at this frequency appears
to be flattening as expected from preliminary model predictions
(IAUC 5762).  A slow decline in the flux density at 1.3-cm should
commence shortly.  The supernova also has flux densities of 37.35
+/- 0.34 mJy at 2.0-cm wavelength (14.9 GHz), 11.77 +/- 0.07 mJy
at  3.6-cm wavelength (8.4 GHz), and 1.70 +/- 0.07 mJy at 6 cm
wavelength (4.86 GHz).  This flux density evolution is consistent
with previous model estimates (IAUC 5762) to within the predictive
capability of the model from the few data points available at that
time.  Revised estimates will be issued shortly.  Radio monitoring is
continuing on a nearly daily basis at these and other wavelengths in
order to follow the supernova's rapidly changing behavior.

   Subj:	Errors in IAUC5774 (SN1993J)

URGENT MESSAGE TO ALL SN1993J INVESTIGATORS

The following observations of SN1993J taken from IAUCircular Nr 5774, 
originating from Xing-Long Observatory do not make sense!  
There must have been a transmission error or something.  
The V magnitudes (column 2) are not too far off (~0.1 mag too faint), 
but the U-B, B-V colors are off by several tenths, and the red and IR 
colors are 1.5-2 mag off.  
DO NOT USE UNTIL CLARIFICATION IS RECEIVED FROM CAMBRIDGE AND BEIJING.
