SNR

The standard photometric equation is 

m = m(0 airmass) + k*X = I + k*X - e(I-J) - Z

where m = -2.5 log_10(flux in photons/sec).

From Walker instrument on the Walker telescope, and comparing to DENIS3, we have (in Namibia) k = 0.1167, e = 0.080, and Z = 21.113.

On July 4 at 2 UT, X = 1.9 from Boyden (South Africa) and 1.2 from Cerro Tololo.

From the DENIS 3 catalog (star J181542.1-181641), we have I = 13.208, J = 11.129, so I - J = 2.08.

For Pluto+Charon, I = 13.27 (taking into account distances and longitudes)

Predictions

Star Prediction Summary

From Norbert Zacharias, Feb 5 2010 

Hi Leslie,
 we did a quick comparison of the available positions of that
star for the 2010.5 epoch.  Looks like no significant offsets
in Dec, some in RA, with UCAC3, 2MASS (+ mean UCAC2/UCAC3 proper 
motions applied) and CMC14 agreeing, while UCAC2 is a bit off .
We should be able to nail this to 15 mas 1-sigma with new URAT
observations.

Norbert

      RA  (ep=2010.5)  Dec     diff RAcosD, Dec (arcsec)
UCAC2: 273.9254889 -18.2781325    with respect to UCAC2
UCAC3: 273.9254667 -18.2781261       0.076  -0.023
2MASS: 273.9254714 -18.2781369       0.060   0.016
CMC14: 273.9254597 -18.2781225       0.100  -0.036

From Marc Buie Leslie - I have a measurement of Bruno's star for July. It's not in the catalog because it's only in the CH4 filter data but I can pull it out by hand. P100704 18:15:42.1035 -18:16:41.079 rasig=0.021 decsig=0.013 This is from 3 measurements so the sigmas are perhaps a bit optimistic. I don't have proper magnitudes but through the CH4 filter this star is definitely brighter than Pluto. The star's instrumental mag is 17.7. I'll dig out the Pluto instrumental mag as soon as I can. This one really looks interesting to me. Yeah, it's at opposition so the velocity is high but the close coincidence with the HST data makes it a bit more attractive along with the ground track. --Marc

From Bruno Sicardy Apr 7 - 04 July 2010, Namibia, RSA, and southern South America. The star is a little bit brighter than Pluto in I band. J2000:

18 15 42.1067 -18 16 41.115


<http://occult.mit.edu/research/occultations/Pluto/PC20100704-preds/index.html>

This discrepancy come from the fact that the MIT Pluto's offset is ~35 mas larger than mine in dec, and that the star is ~40 mas south of our star position (taken from Assafin et al, as of Nov. 2009), so that 75 = +35 - (-40) mas (while the ra's of the star agrees to within 8 mas)

From Jim's web site, April 14 <http://occult.mit.edu/research/occultations/Pluto/PC20100704-preds/index.html> 

PC20100704 Measured3	18 15 42.1073± 0.0080	–18 16 41.155± 0.009	From 3 USNO 61-inch telescope frames.
Data analyzed using UCAC2 reference network. A weighted average of the data from the two telescopes was used to calculate the RA and DEC. The errors given are 1 standard deviation.

UPDATE FROM JIM See http://occult.mit.edu/research/occultations/Pluto/PC20100704-preds/index.html From Jim, June 2 We have analyzed more data and updated our prediction. Our revised star position is RA = 18 15 42.1049 ± 0.0099, and Dec. = -18 16 41.122 ± 0.006. This position accounts for the presence of the companion star, which is 2.8 magnitudes fainter and lies 2.49 arcsec east and 0.92 arcsec south of the occultation star. From Jim June 2' Leslie: The companion star is 2.49 arcsec west (not east) of the occultation star. Jim From Amanda June 2 Leslie, Seeing is usually ~1-1.5 arcsec. Images from nights with worse seeing were not used. Filter is the Navy's A2-1, which is roughly 6150 - 7650 Angstroms. Reference network stars are from the UCAC at date (proper motions to midtime of observation put in for all reference network stars). Exposure times were between 180 and 300 seconds. --a.

From Marc I've been working on astrometry for the occultation star. My current best effort position is 18:15:42.1004 +/- 0.0025, -18:16:41.058 +/- 0.043 based on an average of 18 points taken on 4 separate nights (1 night in 2009 and 3 nights in 2010). This position, if correct, shifts the track quite a bit further south. These data all come from the Lowell 31" telescope with a 24 arcmin FOV CCD camera. Seeing ranged from 3.1 to 4.0 arcsec. The fainter stars ~13 arcsec north and south of the candidate did not affect the reductions. All images were 120 second exposures taken through an 8900A narrow-band methane filter. The astrometry was reduced against UCAC2 corrected to the epoch of the new data.

May 20 notes

Larry, Eliot, Mellissa, Cathy, Marc, Bob, Leslie

Some thoughts about funding. Balance is $131 K. Africa fixed site costs ~$14K ($4K per person per flight, $100/night for 5 nights, 1 week salary). South America fixed site costs ~$10K ($2K per person per flight, $100/night for 5 nights, , 1 week salary). So we could field all 7 cameras. [ Notes added after the call. Leslie: want to hold $80 K for early 2011 event. Buie: Is that a good idea, w/ NASA's issue w/ holding over funds? Leslie: This grant runs until May 5, 2011, so we're OK.]


USNO - no URAT until . UCAC2 astrometric catalog, UCAC3 star catalog (more complete). UCAC4 is which? Russ - no 22-inch portable for this event Folkner - Ephem by June 18. Buie: ctr of light not a big deal, any correction gets enough. Maybe older data given too much weight.

Eliot: Look for Triton candidates? Larry: run against UCAC2. Marc: Ephemeris is good. Only error is good. Cathy: Aug 2010. Eliot: If Triton looks promising, July 4 is expensive, do Triton.

Eliot: Leave telescope in Africa? Marc: We were successful BECAUSE we got to practice. Eliot: don't want drift. Marc: drift inevitable, that's why I bond myself to Walker. Eliot: if leave, it's a new purchase. Marc: nervous about using one stored (or used). And getting good at finding host telescopes. Eliot: Tunisia. Marc: But how many times will we go to Tunisia. That argues for portable. But leaving in Chile might make more sense.

Cathy: Why Namibia and not Chile for the same chord? Marc: Weather. South of Santiago bad for weather.

Leslie: Can we get an answer by June 15? Marc: Try this week, but dodgy. May 28. Larry: Get new data from Monday, for 8 days.

Eliot: Paper work? Leslie: Brazil is horrible for visas. Marc: for equipment too.

Marc: Saa is portal into Chilean amateur community. Work through CTIO - expidited process. Atacama nearly guarenteed weather. Luggage cameras easy to move along coast, would have to drive the telescope. Eliot: amateurs? Marc: don't know how they're set up for occultations.

Leslie: Africa contact? Marc: my hands full with portable. Cathy: what do you want? Leslie: finding fixed telescopes. Marc: would you drop a fixed South Africa site? All: South Africa and Namibia is in Bruno's and near Jim's predictions.

Olkin: branch out, add Triton, large centaurs.

Leslie: This renewal - keep Pluto? Cathy: Just Pluto is a solid science case. Triton, other icy bodies? Eliot: comparison of Pluto and Triton would be good.

Calls for leads on Tuesdays, all on Thursdays.

May 25 notes

Larry, Cathy, Leslie

Hello all,

Cathy, Larry and I talked today (May 25) about deployment in South America and Africa. Here are our conclusions. Let's go over these on Thursday, 9:30 AM MDT, MeetMe Line 866-606-4698

First, some SNR limits (per scale height)

SNR ~10 12-14 " supporting chord (establishing geometry). SNR >25 >26" model fitting. SNR >60 1.5m inversion.

Taking a look at Bruno's map at http://wikivm.boulder.swri.edu/mediawiki/index.php?title=2010-07-04_Pluto_occultation#Globes_and_Ground_Tracks and the list of places I know Jim and Bruno are going at http://wikivm.boulder.swri.edu/mediawiki/index.php?title=2010-07-04_Pluto_occultation#Site_Summary

Telescopes of aperture greater than 26" is probably worth it in Northern Chile, Argentina, Namibia, or South Africa. Once we find out what's available, we can talk about the value (or not) of telescopes on nearly identical tracks with big glass.

Astrometric chords may still be useful in Namibia, if the track is farther south (similar to Bruno's, or even further south). In that case, we might get chords on only one side of the center line, and more chords will help the geometric solution. On Bruno's map, we don't know what the star is at the southern extreme of Namibia. Ignoring that point, there is about half a radius between the larger telescopes (that is, HESS) south of Windhoek (the double stars near Bruno's northern limit) and Boyden (not on Bruno's map, above Lesotho, the circle in the middle of South Africa). There is nothing with a chord south of Sutherland, so something near Port Elizabeth, East of Cape Town and about 1/4 radius cross-track, might be worth it.

Larry, Cathy and I felt that if the track is farther north (similar to Jim's prediction), then there will be chords from Jim, Bruno, or us at Boyden on both sides of the center line, and a supporting chord is not needed in Northern Chile or Argentina. Having said that, I wonder if a portable in the extreme north of Chile might be good (since Brazil will probably get clouded out).

In summary, Larry is looking for 26" telescopes in Chile or Argentina, preferably north of Santiago and will email Oscar Saa.

Cathy is looking for 26" telescopes anywhere in Namibia or South Africa 14" at tracks between HESS and Boyden or south of Cape Town

Leslie

May 27

Melissa Larry Dick Leslie Marc Cathy Bob

Dick - new jobs as Dean for 3 years. Will let us know how much money to send him (we'd been saving it for sabbatical funds). Also, in future - lots of working on papers, maybe not so much observing (but would be delighted to send students).

Larry - Sent an email to Saa - haven't head back yet. Leslie: call on Friday if haven't heard.

Cathy - There's a 26" outside Jburg. Innes. Search Leslie's mail for Innes. Leslie found contact -- lerika@icon.co.za -- and forwarded emails to Cathy.

Marc - hard to carry both S Afr and Namibia options too far. If Namibia - worth a courtesy call. S Namibia out of his range - but could give a hint. If south africa - ask Gulbis for contact. As for who as a partner, it depends on where we're going. If works with Vernon - could do solo. If South Africa or not in. Marc to contact Vernon.

Strawman lineup

  • Boyden, Leslie lead & Larry second
  • Portable, Marc lead. Second TBD (not needed if use Vernon)
  • Innes, Bob lead, Melissa second, also local telescope support. Melissa prefers to leave straight from TNO conference. Maybe SAA 204 JFK June 28 11:15 AM -> JNB June 29 8:15 AM?

Bob will be back in Laramie tomorrow. Want to talk to people about travel to South Africa.

Dec of star is 150 milliarcsec NORTH of Brunos. Moves the shadow south. Urg! Leslie and Larry to look more carefully at predictions tonight.

Next calls are

Leslie Marc Bob Melissa

Bob J'burg. Got reply from Lerika and another (Brian Fraser). It sounds like their interested. Lerika says "sounds exciting." Given the configuration ... last of the big instruments left in Jburg when the rest have been sold off. Astr. Soc S Afr have been restoring it. Using it once a month for public viewing and some of their own work. Clearlu go through them. Like the 24" at Lowell, in the middle of a city. How useable is this? Need to mount camera on back. Hand controls. Setting circles, talk about HA slipping, etc. HARD TO USE.

Buie: Early morning - so stadium dark. And I-band throughput.

Leslie: cranky telescope -- need 2 practice nights.

Bob: public viewing -- last Fri or Sat of the month. Buie: but this will be morning. The amateurs could practice getting that field. Leslie: go out early to Africa, work with Brian a night or two on the Innes, leave a camera there. Leslie: think about changing filter more easily. Bob: why worried about I? Buie: transmission. 3-4 arcsec or better will be fine. Bob: historically, could separate sub-arcsec images. And it's low. Buie: 2 airmasses aren't bad, and refractors can point low.

Buie: If doing this on the Clark 24", would want someone who thinks it's his baby. Bob: that's Brian and Chris.

Bob to continue to email to Brian and Chris. Buie: important to have someone familiar w/ equip on site if we can afford it. Leslie: another idea - Leslie and Larry (or just one) arrive early, bring 2 cameras, work w/ Brian or Chris on Innes and leave one camera with them for the duration of the event.

Buie: portable -- best location just south of Namibia in S Africa. Port Elizabeth is too green near the coast. Confine to S Afr so no double border crossing. Need a second. Melissa?

Bob: 1st game in Jburg June 27 http://www.fifa.com/worldcup/destination/cities/city=1268/index.html

Melissa to practice w/ Marc? Hard to do. Marc in ranch in AZ - don't know what day. Planning June 10, rtn 17. And we don't know the shipping schedule.

Innoculations - needed for Jburg?

Bob: Come down to Boulder, check out camera.

Bob: Ask Brian, Chris about the possibility of leaving camera w/ them? Leslie: Yes.

Predictions - MIT and Brazil agree. 3" star may contaminate Lowell (but why Lowell NE of others? Odd). OK to use just Bruno or mean of Bruno/MIT. Pluto offset - MIT and Bruno's predictions both include Namibia, South Africa.

Tickets - buy by June 15.

Need to talk about travel SOON. Talk Tues June 8 10:30 MDT using MeetMe Line 866-606-4698
