IAUC 8889 (2007 Nov. 2)
COMET 17P/HOLMES
D. Schleicher, Lowell Observatory, obtained eight sets of
narrowband photometry of comet 17P/Holmes on Nov. 1 (r = 2.47 AU)
using the Hall 1.1-m telescope at Lowell Observatory. Projected
aperture radii ranged from 14500 to 120200 km, and derived
production rates exhibited large trends with aperture size for all
species -- with the highest values always at the largest apertures,
consistent with a slowly decreasing rate of overall activity since
the initial outburst. Production-rate ranges for each species are:
log Q(OH) = 29.60-29.80; equivalent log Q(water; vectorial) =
29.54-29.74; log Q(NH) = 27.65-27.89; log Q(CN) = 27.26-27.51; log
Q(C_2) = 27.33-27.61; log Q(C_3) = 26.64-26.87; log [Af(rho)] (526
nm) = 5.13-5.74 (cf. IAUC 7342). The resulting abundance ratios
indicate that comet 17P has 'typical' composition (based on A'Hearn
et al. 1995, Icarus 118, 223), but an exceptionally high dust-to-
gas ratio, possibly associated with the finite lifetimes of the gas
molecules released at the onset of the outburst as compared to long-
lived dust grains. A significant contribution to relatively high
dust abundance may also be caused by a portion of the dust tail
remaining within the photometer apertures due to projection effects
from the comet's small phase angle.
Further naked-eye total-magnitude estimates (cf. IAUC 8887):
Oct. 27.63 UT, 2.4 (Y. Nagai, Gunma, Japan); 28.10, 2.5 (J. Rao,
Putnam Valley, NY, U.S.A.); 28.75, 2.5 (H. Dahle, Les Olives,
France); 29.54, 2.3 (S. Yoshida, Ibaraki, Japan); 30.76, 2.4 (T.
Karhula, Vasteras, Sweden); 31.76, 2.5 (K. Cernis, Vilnius,
Lithuania); Nov. 1.79, 2.3 (J. J. Gonzalez, Leon, Spain); 2.96, 2.5
(A. Pereira, Cabo da Roca, Portugal).

COMET 17P/HOLMES
C. Salyk and G. A. Blake, California Institute of Technology;
M. J. Mumma, B. P. Bonev, M. A. DiSanti, and G. L. Villanueva,
Goddard Space Flight Center; Y. Radeva, University of Maryland; K.
Magee-Sauer, Rowan University; and E. L. Gibb, University of
Missouri, St. Louis, report that they observed comet 17P/Holmes on
Oct. 29 and 30 UT (r = 2.46 AU) using NIRSPEC at the W. M. Keck
Observatory. On Oct. 29, H_{2}O (eleven lines, 2.9-micron hot
bands), C_{2}H_{6} (eight Q-branches, 3.35-micron nu_{7} band),
C_{2}H_{2} (four lines, 3.0-micron nu_{3} band), HCN (nine lines,
3.0-micron nu_{3} band), and CH_{3}OH (3.52-micron P-, Q-, R-
branches, nu_{3} band) were detected. Rotational temperatures for
H_{2}O, HCN, and C_{2}H_{6} were about 60 K. All lines were
strongly peaked on the nucleus region, as expected for parent
volatiles. Preliminary production rates (x 10^{27} molecules/s)
are: H_{2}O, 275; C_{2}H_{6}, 5.9; C_{2}H_{2}, 1.5; HCN, 1.5; and
CH_{3}OH, 11. The abundance ratios are: H_{2}O : C_{2}H_{6} :
C_{2}H_{2} : HCN : CH_{3}OH = 100 : 2.2 : 0.54 : 0.54 : 4.0.
Comet 17P seems to be enriched in organics, like C/2001 A2. On
Oct. 30, abundance ratios for H_{2}O, C_{2}H_{2}, and HCN were
similar to those on Oct. 29. The R0 and P2 lines of CO (4.7-
micron 1-0 band) were detected; if T_{rot} = 60 K, the formal CO
abundance is 14 (+/- 4) relative to water (100).

COMET 17P/HOLMES
M. Drahus and L. Paganini, Max-Planck-Institut fuer
Sonnensystemforschung; and L. Ziurys, W. Peters, M. Soukup, and M.
Begam, Arizona Radio Observatory (ARO), report their monitoring of
comet 17P at millimeter wavelengths between Oct. 25.5 and 31.5 UT
with the ARO 12-m telescope on Kitt Peak. Evolution of the
outburst was traced through the HCN(1-0) transition. The following
integrals of the antenna temperature were obtained, with the three
hyperfine components summed, given in units of K km/s: Oct. 25.54,
5.0 +/- 0.1; Oct. 27.58, 1.3 +/- 0.1; Oct. 28.38, 0.58 +/- 0.05;
Oct. 30.40, 0.62 +/- 0.05; Oct. 31.50, 0.39 +/- 0.06. The gas-
expansion velocity, measured on the blue wing of the strongest HCN
line component, was fairly constant during the observations and
equal to 0.50-0.55 km/s. The shapes and intensities of the HCN(1-0)
triplet on Oct. 25.54 and 27.58 confirm the presence of the "chunk",
and the isotropic "bubble" (cf. CBETs 1111, 1118), the "chunk"
being redshifted with respect to the nucleus. Both features were
continually fading, likely due to photodissociation and because of
moving away from the beam center. Since Oct. 28.38, the "chunk"
has not been visible in the line shapes, and the intensity of
HCN(1-0) has simultaneously stabilized; therefore, the measurements
obtained since then likely result from a regular (non-explosive)
post-outburst activity of the nucleus. On Oct. 26.51, five lines
of CH_3OH were detected around 157 GHz, whose relative intensities
give a rotational temperature of 50 +/- 5 K. The area of the
strongest line, 4(0,3)-4(1,4), was 0.78 +/- 0.04 K km/s. Also
detected were CS(3-2) on Oct. 26.58 (1.48 +/- 0.04) and 29.38 (0.25
+/- 0.02); H_2CO(2(0,2)-1(0,1)) on Oct. 27.53 (0.08 +/- 0.04); and
H_2S(1(1,0)-1(0,1)) on Oct. 31.41 (0.13 +/- 0.02). Sensitive 3-
sigma upper limits were obtained on CO(1-0) on Oct. 25.64 (< 0.2;
however, a positive residuum of 0.05 is visible) and 27.46, (<
0.08). The half-power radius of the beam ranged from 19" to 36",
depending on the observed frequency. The absolute calibration and stability
of the instrument is estimated to be better than 20 percent.
