1994 04 02.19 &4 of Orange County Astronomers and Sunsearch on Apr 2.1527 UT.
1994 04 02.19 &5 Its presence was subsequently confirmed using the 0.55-m
1994 04 02.19 &6 Kuhn f/8 telescope. Imagery with 500x256 CCD camera was
1994 04 02.19 &7 obtained on the 0.55-m and also a 0.105-m refractor. The
1994 04 02.19 &8 observations were secured in excellent sky conditions.

3100 From Brian Skiff (bas@lowell.edu):
3110
3120 The most useful comparison for the supernova in M51 for CCD observers
3130 is likely to be the fairly bright star about 90 arcsec southwest of the
3140 center of the galaxy in the interarm region. The Longo & de Vaucouleurs
3150 aperture photometry catalogues list several values for this star, all
3160 due to otherwise unpublished measures by Harold Corwin:
3170
3180 V B-V U-B V-R R-I V-I
3190 "135" 13.48 0.59 0.17 0.36 0.33 0.69
3200 13.46
3210 13.41 0.59 0.04
3220
3230 Presumably the discrepancies in V and U-B are due mainly to the
3240 difficulty of subtracting the background light with single-channel
3250 photometers. This star does not appear in the Guide Star Catalogue.
3260
3270 A second fainter star with photometry is located about 90 arcsec
3280 south and 20-25 arcsec east of the center. This star does appear in
3290 the GSC as GSC 3460-0588 and is marked "151" on the Thompson & Bryan
3300 chart. The photometry again is the otherwise unpublished observations
3310 by Harold Corwin.
3320
3330 V B-V U-B V-R R-I V-I
3340 "151" 15.11 1.38 0.98
3350 15.10 1.59 0.17 0.70 0.74 1.44
3360
3370 As noted before, the discrepancies are presumably due mainly to the
3380 difficulty of subtracting the background light with single-channel
3390 photometers, and for the fainter star, just sheer faintness. For this
3400 reason, probably only the VRI colors are well in hand for this star.

3800 From Harold Corwin (hgcjr@ipac.caltech.edu):
3810
3820 Here are my full photometric data for some of the comparison stars on
3830 on the Thompson-Bryan chart for NGC 5194. The observations were made
3840 with the 76-cm reflector at McDonald Observatory on four nights in
3850 1982, '83, and '85.
3860
3870 With the possible exception of the brightest star, these data are not
3880 as reliable as those for the NGC 3031 sequence which I sent out to the
3890 net a year ago (and recently published with de Vaucouleurs and Skiff
3900 in the Feb '94 PASP). In particular, the three faintest stars are
3910 superposed on the galaxy, so the background subtraction is quite
3920 uncertain for them. The errors quoted on the two stars observed on
3930 more than one night are internal standard deviations for one
3940 observation, rather than mean errors on the mean values.
3950
3960 Data for the faintest star should not taken seriously. Though its
3970 U-B was measured both nights, the U signal was too faint to derive a
3980 meaningful color index. The error on V is fortuitously small.
3990 Brian Skiff has already sent out the dirty details on this star --
4000 please ignore them, and don't pay much attention to these "mean"
4010 values, either. They are "indicative," nothing more.
4020
4030 All these stars should obviously be reobserved, but the data for "135"
4040 should be adequate for preliminary reduction of CCD frames.

4200 From Brian Skiff (bas@lowell.edu):
4210
4220 I have now measured two somewhat brighter stars near M51 for the use of
4230 visual observers in estimating the brightness of the supernova. The
4240 results should not be taken as definitive for more exact purposes,
4250 based as they are on single measures with a relatively small telescope.
4260 They should be entirely satisfactory for visual use, however. The
4270 values are V and Stromgren (b-y), done with the Lowell 53cm photometric
4280 telescope. 29-arcsec aperture, five primary four-color standards
4290 measured with these, whose rms uncertainties from the fit were 0.004 in
4300 V and 0.006 in (b-y). I measured the brighter star GSC 3463-0058 ("113"
4310 on the T&B chart) as a consistency check; my value is somewhat brighter
4320 than what's given on the chart.
4330
4340 The stars are listed below with GSC positions. The values in the second
4350 line of each magnitude entry are the rms uncertainties of the batch of
4360 integrations times the rms error in the fit to the standards taken in
4370 quadrature.
