SN 1993J fans:
Here are some updates.
Alex Filippenko

Alain Porter (porter@noao.edu) reports that he has a compilation
of published UBVRI photometry of stars in the M67 dipper field (used
by many for calibration purposes). He is willing to send it on an
individual basis to anyone who asks.
****
Harold Corwin (hgcjr@ipac.caltech.edu) finds that the GSC magnitudes
of the comparison stars are too bright by about 0.45 mag with a scatter
of around 0.1 mag -- but there are two ringers which are much further
off. It does not look like there is a significant color term in the
transformation. Here are the details:
Daniel Green at the IAU Central Telegram Bureau in Cambridge tells me
that there has been some confusion about the identity of the stars in the
UBVRI sequence that was published in IAUC 5742. In short, I can find no
problem with the identifications of the stars in either my own records, or
in the Circular. Here is the longer story: I have checked my original
finding chart of the field and find that I adopted the sequence nomenclature
of Brandt, Kalinowski, and Rosen (ApJS 24, 421, 1972) on that chart; the
nomenclature in my nova net message of 5 April is based on the right
ascensions from the GSC. The data were transferred correctly to the
Thompson-Bryan chart of N3031 from my photoelectric reduction output, and
the GSC identifications -- based on the GSC positions in my table sent to
Drs. Green and Marsden -- in IAUC 5742 are also correct.
The following table collects all the photoelectric data which I know
about now for stars in the Thompson-Bryan field. The sources (given in
the "Other" column followed by the star identification within the source)
are:
JN -- J. Neff, in Brandt, Kalinowski, and Rosen. 1972, ApJS 24, 421.
BH -- Brandt and Hiltner, ibid.
AS -- Sandage. 1984, AJ 89, 621.
HC -- Corwin. 1993, IAUC 5742.
TK -- Kato. 1993, April 6-11, nova net messages.
OI -- Okyudo and Ishida (in Kato. 1993, April 6-11, nova net messages).
Unfortunately, I do not know the sources of the other sequence data which
G. de Vaucouleurs has requested (the AAVSO sequence, and the sequence from
"The Astronomer"). [I have since had notes from Guy Hurst and Janet Mattei
on these. The sequence in "The Astronomer" is essentially that from the
Thompson-Bryan Atlas, while the AAVSO sequence is a preliminary visually-
determined one.]
Nor do I find any optical photometry for star "C" aside from the GSC value
of 14.59. Using de Vaucouleurs's zero point correction, this becomes
V = 14.96. S. Odewahn, C.E. Woodward, and J. Bailey give JHK data for
stars "A", "B", and "C" in a nova net message of 9 April. Within the
errors, star "C" has the same colors as stars "A" and "B". This suggests
V = 14.4 for star "C", in poor agreement with the corrected estimate from
GSC. M. Kidger, however, has reported that star "C" has been listed as a
possible variable. While the estimates I've just made point to the same
conclusion, we obviously need more photometry for this star.
With two exceptions, all the stars are in the GSC whose positions I quote.
For the two exceptions (Sandage's stars 2 and 21), I have estimated the
positions with respect to nearby GSC stars.
The label on the Thompson-Bryan chart for GSC 4383-1031 is incorrectly given
as "11.6." This should either be changed to "11.7" (to report the V magnitude
given by Brandt, et al), or to "11.6 overline" to reflect the V which I
measured.
Finally, note that the U-B, V-R, and V-I values from my observations are on
the Cousins system, while other U-B values are (probably) on the Johnson
system. Dr. Kato also reports his I-band photometry for star "A" to be on
the Cousins system.

Hi Alex
I have some remarks on the early IUE spectra of SN 1993J that you
might like to distribute in your electronic journal which I've been calling
SN~1993J Updates. I would like to emphasize that many others are examining
the IUE spectra, and they will have seen more of them than I, and in most
cases will know far more about analyzing interstellar and circumstellar
matter from IUE spectra. So any valid remarks I make will probably be old
news to many.
I have examined low resolution short wavelength (\sim 1150--1950 A)
IUE spectra from Mar.~30 to April 4 and low resolution long wavelength
(\sim 2000--3300 A) IUE spectra from Mar.~30--31. These spectra were
emailed to me by George Sonneborn who collaborates with Robert Kirshner (my
boss) on IUE observations of supernovae. The March~30 spectra seem to be
the earliest taken; March 30 was about the epoch of maximum light. The
first spectrum rises blueward right across the IUE band from about 3300 A
to about 1240 A. (I consider the spectra in the f_lambda representation.)
>From about 1200 to 1220 A, there is the solar coronal Lyalpha emission
feature which is of no interest here. Below 1200 A the IUE spectra are
quite noisy, but more examination than I have done might yield some
information. By March 31, the UV spectrum had become rather flat, but
declining somewhat redward. After March 31, the short wavelength IUE
spectra decline redward and there appears to be a broad (i.e., about 80 A)
depression centered at about 1630 at least before April~4. Apart from the
Lyalpha emission, the 1630 depression, and another broad depression center
at about 2200 A (see below), there are no other obvious broad features in
the spectra.
An interpretation of the early SN~1993 UV spectra, that is already
widely discussed (e.g., Wheeler 1993), is that we are seeing a
circumstellar wind at least for March 30--31. The circumstellar wind has
been heated by the UV flash of the supernova outburst and is cooling
rapidly on March 30--31. The wind is moving slowly. High resolution
spectra from March 30 show strong narrow emission features at the
wavelengths of the N V doublet, 1238.81 and 1242.80 A; I have only seen
these spectra on a FAX. The 1238.81 emission is weaker and narrower (only
about 100 km/s); the 1242.80 feature is about 20 % higher, has a breadth
of about 200 km/s, and exhibits a narrow blueshifted absorption of about 50
km/s in width which appears to be a P~Cygni absorption. It is odd that the
1242.80 feature is more prominent since the N V 1242.80 line has only half
the gf of the the N V 1238.81 line. If these features are due to N V in the
circumstellar wind, then they suggest wind velocities up to 200 km/s and a
wind temperature (assuming LTE) of order 20000--30000 K for March 30.
It may be that after March 31, we are seeing the supernova ejecta and
that accounts for the depression that appears at about 1630 A. Broad
absorptions are what one would expect from rapidly expanding ejecta and are
what I had expected to see in the earliest IUE spectra. However, optical
P~Cygni lines were only seen on April~6.3 (Wheeler \&~Clocchiatti 1993).
Thus, 1630~A depression may just be some sort of modulation of the
circumstellar flux.
The low resolution spectra are quite noisy but show several narrow
absorption lines. The low resolution mode of the IUE has a resolution of
about 1 in 300 or 1000 km/s (5 A at 1500 A and 10 A at 3000 A). It is
probable that none of the narrow features is resolved. One absorption at
about 1545 A is probably the C IV 1549.1 ground level multiplet and is due
to the circumstellar material. This absorption disappears after April 1;
presumably, the circumstellar material temperature has fallen too low by
then for C IV.
The other narrow absorptions are probably interstellar lines. I have
identified the Mg II 2798 resonance doublet with the two lines barely, but
definitely resolved. The Fe II 2343, 2382, and 2599 ground level lines
also appear in the long wavelength IUE specta; these Fe II lines are all
strongest lines of widely spread multiplets; I can't identify any of the
weaker multiplet lines. In the short wavelength IUE spectra, I identify the
Si II 1263, 1308, and 1531 ground level multiplets and the Al II 1671 and C
II 1335 ground level multiplets. These lines are typical UV lines due to
the interstellar medium (e.g., De Boer, Jura, \&~Shull 1987).
Another narrow absorption is at about 1795. It seems too far to the
blue to be due to the comparatively weak Si II 1814 multiplet, but there is
a difficulty with the wavelength calibration that may allow this
identification (see below). The absorption may, of course, be
circumstellar.
Except for the Mg II resonance lines, none of the absorptions are
clearly resolved into component absorptions either due to the various
multiplet lines or different interstellar media at different velocities in
the Milky Way and M81. This is not surprising given the low resolution of
the low resolution mode of the IUE and the fact that M81 has a small
heliocentric velocity (-43 km/s; Tully 1988). The centroids of absorption
features in the IUE spectra all seem to be shifted by varying amounts of
order a few angstroms both to the red and the blue. This probably because a
definitive wavelength calibration has not been done.
High resolution IUE and HST spectra will probably allow a much better
study of the interstellar lines. HST spectra were scheduled to be acquired
on April~15 as part of the SINS program (Kirshner~\etal 1988). Since all
the people connected with that observation have been away from CfA since
then, I have had no information on what was acquired; presumably the HST
observations will soon be subjected to study.
The broad depression in the IUE spectra centered at about 2200 A is
almost certainly due to the 2175 A bump in the interstellar extinction
(e.g., Cardelli, Clayton \&~Mathis 1989; Mathis 1990). This bump is
believed to be due to carbon grains possibly in the form of graphite. The
bump is a regular feature of UV extinction and is present for all values of
R_V. It has a FWHM varying between about 400 and 800 A. The depression in
the IUE spectra seems narrower than this and has a breadth at the base line
I draw of only about 400 A. The IUE spectra are particularly noisy in the
2000--2400 A region, and so the existence of the depression could be
challenged. However, given the presence of the interstellar lines and the
existence of foreground extinction (Burstein \&~Heiles [1984] report a
foreground E(B-V) of 0.0375), an extinction depression is expected. I have
tried to eliminate the depression by correcting the spectra using R_V=3.1
(the standard value for the diffuse interstellar medium) and extinction law
of Cardelli~\etal (1989). The most satisfactory E(B-V) value I find is
0.10 and I estimate an uncertainty of 0.03. An E(B-V) value as high as 0.2
must I think be completely ruled out since correcting the spectra with
E(B-V)=0.2 creates a prominent bump centered at about 2150 A.
I hope people will quickly emend an errors I have made. I'd like to
thank Jason Pun for some information on IUE observations.

SUPERNOVA 1993J IN NGC 3031
M. P. Rupen and R. A. Sramek, National Radio Astronomy
Observatory; S. D. Van Dyk and K. W. Weiler, Naval Research
Laboratory; and N. Panagia, Space Telescope Science Institute, report
new observations of SN 1993J made on 13 April 1993 at 6 cm
wavelength (4.86 GHz) with the Very Large Array in 'B'
configuration. Two separate observing sessions on that day yield flux
density values of 0.33 +/- 0.08 and 0.28 +/- 0.05 mJy. These
measurements confirm the possible detection of radio emission at 6 cm
on that same day recently reported by Strom (IAUC 5762). Such a
value is also consistent with the model results reported by Panagia,
Van Dyk, and Weiler in IAUC 5762. From the model, SN 1993J is
expected to strengthen rapidly in this radio band and reach a peak of
about 30 mJy by 20 May 1993. Radio monitoring with the VLA is
continuing on a nearly daily basis at this and other wavelengths in
order to follow the supernova's rapidly changing behavior.
