Whence the orbital details (inclination, etc.)?

(Copy of answer received through e-mail):

The orbital elements come from C. C. Porco et al. Cassini Imaging Science: Initial Results on Saturn's Rings and Small Satellites. Science, Vol 307, Issue 5713, 1226-1236 , 25 February 2005, http://www.sciencemag.org/cgi/content/short/307/5713/1226

Volcanopele

I've added the reference to the page's links. Thanks.

Hi, similar question to above. It'd be great to include some kind of reference for the improved diameter estimate. If it's not put in, it becomes a bane a year or two down the track because it can become hard to track down where it came from, and doubts appear :-) Deuar 22:38, 30 May 2006 (UTC)[reply]

Done and Done. I should also note that recent disk resolved images seemed to confirm this size, which I what reminded me to change that number.--Volcanopele 22:59, 30 May 2006 (UTC)[reply]

That was fast! By the way thanks for all the excellent research on Saturn's icy moons you Cassini guys have been doing, and the way it's released rapidly to the public. It's really appreciated. Deuar 23:11, 30 May 2006 (UTC)[reply]

Enceladus

Just wanted to commend you on the great job you've done on not only the Enceladus article itself, but the pages for its surface features! I think they are an example that the rest of the surface feature pages should be worked on to match. Keep up the great work! --Patteroast 17:34, 17 July 2005 (UTC)[reply]

Congratulations on getting this to featured status. Great article, I enjoyed reading it. --BillC 16:20, 2 June 2006 (UTC)[reply]

Hi, I noticed you cropped the Enceladus image even further (which is fine, though I prefer at least some blackness around it), but what strikes me is the image appears much sharper. Did you sharpen it, because I already applied a smart sharpen in Photoshop CS2? This just looks too excessive even for my taste, it's starting to get that Voyager processing feel to it. Ugo 07:01, 24 October 2006 (UTC)[reply]

I can revert it, no problem. The sharpening is meant to remove some of the smoothing effects caused by the PSF, I'll let you mess with that to your liking. I trimmed it so it would work better as the title image. --Volcanopele 18:03, 24 October 2006 (UTC)[reply]

Alright, a new cropped version is up, but without additional sharpening as it was already sharpened (the "smart sharpen" filter used actually does something similar to deconvolution). Ugo 20:35, 24 October 2006 (UTC)[reply]

newly named Uranus moons

Hello, you have recently changed some Uranus moons to the names Cupid, Mab, Perdita, Francisco and Ferdinand. Can you please give me a reference for the naming of these satellites, as i was not able to find an official confirmation.

Thanks, --Gunter.krebs 19:41, 11 December 2005 (UTC)[reply]

http://planetarynames.wr.usgs.gov/append7.html contains a list of Satellite names provided by the organization that does the naming. Definitely the first place to check for new official names. Volcanopele 17:56, 12 December 2005 (UTC)[reply]

Thank you very much for the info --Gunter.krebs 10:07, 13 December 2005 (UTC)[reply]

Allow me...

		The E=MC² Barnstar
		For your awesome drive of Enceladus (moon) to FA status, I hereby bestow you this EMC² Barnstar! Grafikm ^(AutoGRAF) 16:23, 2 June 2006 (UTC)[reply]

Sweet!! Thank you so much. Now on to another moon... --Volcanopele 19:46, 2 June 2006 (UTC)[reply]

How about Titan? Reyk _YO! 23:56, 2 June 2006 (UTC)[reply]

sigh* I might as well. It is on my to-do list. Personally, I'd prefer to start by infusing the other major Saturnian moon articles with Cassini-derived info. The Mimas article doesn't even have some of the best images taken by Cassini of the surface. The Janus article has no image from Cassini. The Titan article is in serious need of rehauling. I have suggested an outline in the talk page, but I haven't had time to implement it. --Volcanopele 00:40, 3 June 2006 (UTC)[reply]

Venus

Hi there! I saw the Astronomy collaboration of the week you added to Venus. You might like to know that Venus is currently a featured article candidate. Within the last few weeks, Worldtraveller and I have created a new version, which has been nominated for FA status. You might like to add comments on the current article there. Regards, BillC 21:45, 13 June 2006 (UTC)[reply]

sigh* okay, ACOTW changed to Mars. Thanks for the heads up. --Volcanopele 22:02, 13 June 2006 (UTC)[reply]

Eritrea

I was wondering if you would be interested in helping me improve the article Eritrea to FA status? I think it already has plenty of content it just needs to have its language cleared up. If you would I would really appreciate it! Merhawie 18:57, 27 August 2006 (UTC)[reply]

Europa (moon)

I like the work youve done on Enceladus, and would like for Europa to become a GA, it needs a copy-edit/cleanup... and you seem to do a good job, reckon you could pop over and have an edit? -- Nbound 05:44, 26 September 2006 (UTC)[reply]

Laomedeia?

I noticed the new names on the Neptune's natural satellites page, so I went to add them onto the Timeline of Natural Satellites... after I did so, I noticed the link to Laomedeia redirected to Halimede, by your edit. I'm quite confused by this point. What's going on? --Patteroast 23:03, 30 January 2007 (UTC)[reply]

I got confused as to which name applied to S/ 2002 N 1. So I first moved that article to Halimede, then to Laomedeia. When I got an email from the IAU naming group about which names applied to which moons, I moved it back to Halimede. However, because of that incorrect move, Laomedeia redirects to Halimede. For now, use Laomedeia until we can get that fixed. --Volcanopele 23:14, 30 January 2007 (UTC)[reply]

I have submitted a request for an uncontroversial move of S/2002 N 3 to Laomedeia (moon). In the meantime, Laomedeia (moon) now redirects to S/2002 N 3, as it should. RandomCritic 09:09, 1 February 2007 (UTC)[reply]

The move to Laomedeia (moon) has been completed. RandomCritic 11:37, 3 February 2007 (UTC)[reply]

SATELLITES OF 2003 AZ_84, (50000), (55637), AND (90482)

     M. E. Brown and T.-A. Suer, California Institute of Technology,
report the discoveries of four satellites of large transneptunian
objects from observations with the Hubble Space Telescope High
Resolution Camera (+ F606W filter).  Observations of (55637) 2002
UX_25 on 2005 Aug. 26.64 UT detected a satellite that was 2.5 +/-
0.2 mag fainter than the primary at a separation of 0".164 +/-
0".003 in p.a. 153 +/- 2 degrees.  Observations of (90482) Orcus on
2005 Nov. 13.13 detected a satellite that was 2.7 +/- 1 magnitude
fainter than the primary at a separation of 0".25 +/- 0".01 in p.a.
128 +/- 1 deg.  Observations of 2003 AZ_84 on 2005 Dec. 2.99
detected a satellite that was 5.0 +/- 0.3 mag fainter than the
primary at a separation of 0".22 +/- 0".01 in p.a. 321 +/- 2 deg.
Observations of (50000) Quaoar on 2006 Feb. 14.90 detected a
satellite that was 5.6 +/- 0.2 mag fainter than the primary at a
separation of 0".35 +/- 0".01 in p.a. 110 +/- 1 deg.



V1281 SCORPII

     H. Naito and S. Narusawa, Nishi-Harima Astronomical
Observatory; and H. Yamaoka, Kyushu University, report that a
low-resolution spectrogram (range 410-670 nm; resolution 1600 at
H_alpha) of the possible nova reported on IAUC 8810 was obtained on
Feb. 21.84 UT with the 2.0-m NAYUTA telescope (+ MALLS).  The
spectrum shows a broad H_alpha line with a P-Cyg profile (the FWHM
of the emission component is about 1800 km/s), along with many
other weaker lines, indicating that the star is indeed a classical
nova.  A narrow Na I D absorption feature suggests the existence of
considerable interstellar reddening.  Yamaoka adds that Y. Fujita
(Kuma-Kogen, Ehime, Japan) made a prediscovery CCD image of the
area of the nova with a Nikon D50 camera (+ 105-mm f/2 camera lens)
on Feb. 18.850, and the nova was not visible to limiting mag 11.6.
     N. N. Samus, Institute of Astronomy, Russian Academy of
Sciences, reports that this nova has been given the designation
V1281 Sco.



V1280 SCORPII

     C. Buil, Castanet, France, reports that an optical spectrogram
of V1280 Sco obtained on Feb. 20.20 UT using a 0.28-m Schmidt-
Cassegrain telescope (+ Lhires spectrograph) shows an H_alpha P-Cyg
profile and a FWHM of 730 km/s; the intensity of the H_alpha peak
intensity is 2.3 times the local 670-nm continuum.  CCD magnitudes
by J. D. West, Mulvane, KS:  Feb. 21.467 UT, H = 2.87 +/- 0.06;
21.483, V = 4.73 +/- 0.01.
