== Meeting from 10/9/2007 at Oil City High School ==
We are going to get started monitoring our brighter T-Tauri candidates and generating light curves for them in the R and I band.
I (S. Weiser) have selecetd two targets to monitor:
SSTiau Name is 050511.5-064346, RA = 5h 5m 11.6s, DEC = -6d 43m 46.9s, Rmag = 15.3
SSTiau Name is 050517.4-063734, RA = 5h 5m 17.5s, DEC = -6d 37m 34.3s, Rmag = 16.7
Estimated exposure time - 180sec
Using http://heavens-above.com and The Sky planetarium software I've estimated we will want to be on the telescope in Perth Australia sometime between 3:00 PM and 5:00 PM EST throughout October and November.  Does everyone else agree?
Using the New Mexico Sky telescope (near El Paso, Texas), we will need to be on the telescope between 6:00 AM and 7:30 AM EST.  Does everyone agree?
== Meeting 10/17/07 At OCHS ==
These are the Targets I have chosen to monitor.-Nick_
SSTiau Name is 050730.1-061015, RA=05:07:30.2 DEC= -06:10:15.9
SSTiau Name is 050730.6-061059, RA=05:07:30.6 DEC= -06:10:59.7
Exposure time of 180secs, Viewing time from Oil City 2:00pm-5:00pm Est, will be using the Perth Telescope.
== Telescope Time Reserved ==

== Failed attempt ==
    First attempt to take an image using Perth Failed Due to Weather. 10/17/07
My targets are
      : 409 RA- 76.854562 5hr7min25.1sec  DEC- -6.238076 -6d14m17.1s R Mag17.3

1) is it giong to be interactive or informational?
    a) are people going to be able to "plug in" the information and it's going to spit out a light curve?
  b) is it just going to be a "follow along paper" telling them how to do it step by step?
== Perth Observing results 10/22/2007 ==
From Dani ... we tried observing T-Tauri targets using the telescope.  Weather looked good at 3:32 PM EST, but telescope stated "Conditions were not sufficient for Observing".    Nick K also tried earlier, but got the same results.
== Observing Results 10/23/2007 ==
FROM DANI.... Tried to image at 13:31 EST and this is what it gave me...

TRY - AGAIN  ..... TRY AGAIN  ..... TRY AGAIN" .... this seems to happen alot. it happened to nick also when he tried to image just a few minutes before I did. is something wrong with the telescope? When I checked whether conditions it was clear and the windspeed was at 6.7, so the conditions should have been fine....... i tried again at 13:37 and it stated the same thing. pattern? okay, so it just toldme at 13:39 that the whether conditions were insuffecient or something along those lines... ''what exactly are the ideal conditions?'' [end of Dani post.]
== Perth failure ==
From Nick, today I attempted to image my targets at 13:15 est and again at 15:31est.        Both times the imaging failed due to some internal problem with the Perth Telescope. I then tried at 16:20est.
From Matt H, I also attempted to image my targets at 16:00 est. At this time the imaging failed for some reason that has to do with Perth Telescope
FROMDANI... I also attempted to image and got the same results as Nick and Mattheath

== Perth ==
-Nick- Once again today Perth was unable to take images, while trying to firgure out the problem with the telescope we e-mailed Perth. They responded saying that there weather sensor had goon bad and they were having trouble with the new one.
== Failure ==
Once again today i attempted to image using perth and it is not working due to clouds and wind. Nick-11/08/08
== First Images 11/09/07 ==
Today at 1:38est I was able to get the first set of images from Perth. -Nick-
........DANIELLEYEAGER... 11/15/2007_23:57EST
What images exactly, did you collect? Only your targets or others as well?
NicK- I collect everyones field when i view, well as many as I have time to get and as long has Perth is corporateing.
== practice light curve data ==
''....DANIELLEYEAGER.. 11/15/2007_23:55EST
Would you like our practice light curves posted on here? If so, do you want our entire spread sheets as well as the graph; or just one or the other?........''
RESPONSE:  Dani, yes if you can post them here that would be great.  Thanks, Mr. Spuck
== practice light curve .... ==
'''''........DANIELLEYEAGER.... 11/19/07 15:11EST'''''
today during 7th period mr.spuck pulled the IC2118 group aside and discussed how far we had gotten with the practice light curve and the wiki.
i am almost done with my light curve. i used the HOU [hands on universe] program to collect my data. fast and easy. However, there were only 4 constants in the images, two of which being my targets. once I create the spread sheets along with the graph, I will try to find a way to get them on here along with a step by step on how I did it.
mr.spuck saved a file into the practice folder showing 13 reference points, he also posted them on the wiki in section 17 of the discussion. i'm going to have to go back into my data and force HOU to spit out that information.
== participants ==
where is everyone? nick and I seem to be the only ones posting.
Nick- I agree with Dani if other participants want to be a part of this communication is vital.

When I image for all the people in the project I get everyones images-Nick
--[[User:Spuck|Spuck]] 10:53, 4 December 2007 (PST) Nick, rather than saying "everyone", could you just list the fields and the filters used for each observing session.  For Example, list it as:
Nick's field -  R 180 sec, I 180 sec
Dani's field -  R 180 sec, I 180 sec
Matt's field -  R 180 sec, ... got cloudy and I did not get I
This way we know exactly what has been imaged.

.......11/30/07 1017est......... okay, so I made a really REALLY beginner mistake and completly forgot about the fact that I had to use julian date. SOOO.. I will post a new thread with the updated information.
.....11/30/07 1042EST.............. i guess it's just a day for mistakes. i was using the file image name rather than the date and time from the header. so, i have to do the dates over again AND THEN convert into julian time.
--[[User:Spuck|Spuck]] 10:45, 4 December 2007 (PST)  Dani, when you write ratio C and ratio D, what do you mean?  You are dividing what by what?  Also, did you follow the directions from the activity we are working showing you how to generate a light curve.  In the activity one of the things you are asked to do is convert to Julian time.
--[[User:Danielle|Dani]] 10:49, 4 December 2007 (PST) TSpuck, Ratio C means the Candidate C divided by the average of the references. Ratio D means the Candidate D divided by the average of the references. And no, I did not use the activity worksheet.  [end]

== Practice Light Curve and Loop Problem ==
..............DANIELLEYEAGER  11/30/07 1336EST
After figuring the Julian Date for the data, the light curve started to loop. By loop, I mean that the dates stacked fairly close to right above one another and circled through them forming a loop. By this loop problem, I've made the assumption that if a set of data has several points that are seconds or minutes apart, the data will loop. To solve the loop problem I averaged together the points that formed the loop and had that as my point. Doing so decreased my data points severely, but did work in achieving my desired goal.
NOTE .... when uploading pictures make sure to use EXACT title. example.. if the file name is uploaded as graph2.JPG you must type exactly, example capatalizing the JPG.

Also, does anyone know how to set up a graph in excel so that you only connect some of the data points being graphed?  Thanks.

Tried to get on perth and take some images. Telescope was in use by perth. I did go into the images we have already taken and saved some of the images titled Daniscandidates to my personal computer. I don't really know what to do with them though. How many pictures do we have that are focused on my center? Should I start getting the data pulled together and working on my real light curve now that I am finished with my practice light curve? Or should I simply focus on mastering the wiki?
--[[User:Spuck|Spuck]] 11:18, 4 December 2007 (PST)  Dani, you're doing a great job with the Wiki.  Unfortunately the Perth Telescope is down for now. I just found out today that the RA motor went bad in the mount.  I will post more news as I get it.  We will probably have to start using New Mexico Skies telescope for our observations.  This means being up at 2:00 AM EST ... any volunteers?  For now, why don't you focus on working with the rest of the team ... bringing them up to spped on how to access and use the Wiki, as well as working through the Wiki to see what we should focus on in our AAS Poster.
1615 est
While trying to save over my images, when clicked, some files opened to a page showing the picture directly, where as others had a prompt coming up asking whether I wanted to find the image or save the image. Why?
--[[User:Spuck|Spuck]] 11:18, 4 December 2007 (PST)  Dani, I'm not sure.  WHy don't you show me this when you have a chance.  Thanks.
== 12/2/07_2226 est ==
dumbie me, i went to log on and do some imaging, but then i realised that it was like.. 10 in the morning. so keep in mind when imaging the +12 to +13 hour time difference.

Once again Perth is down.
--[[User:Spuck|Spuck]] 11:39, 4 December 2007 (PST)  Nick, Perth will probably be down for a bit.  See my previous post to Dani.  Also, your light curve looks similar to Dani's.  That's good and bad. :) Can you check with Dani and answer the following question for me and then post your responses:
1. Did the two of you use all the same reference stars?
2. Did the two of you use the same software to get the brightness values for your reference stars and YSO candidates?
Also, I'd like to se you modify your graph a bit.  Label the Y axis more clearly (don't just say ratio ... ratio of what?).  Also, turn the julian dates (ie. like I had Dani do hers).  And use the scatter plot with the line connecting the data points. Also correct your spelling error in the graph title. Thanks.
--[[User:Nicholas|Nicholas]] 10:36, 6 December 2007 (PST) Well Mr. Spuck Dani walked me through what to do with the Light Curve so it would be understandable why our light curves would be similar. [end]
--[[User:Danielle|DanielleYeager]] 09:59, 7 December 2007 (PST) 1.) I don't know if we used the same reference stars, but I do know that he used MORE reference stars than I did.
2.) I used HOU.
==12/3/07_2048 est==
Today, stayed after with Alexis, Danielle, Cale, and Alix in Mr. Spuck's room. Took notes on basics of things for the Austin trip. Parents signed the permission slip and are pleased with the trip. Mom's meeting with Mr. Spuck went well, obviously.
2:40-5:10, worked on galaxy research.
Tomorrow, doing notes on the book Mr. Spuck gave me.
I officially have my hours as of today. :)
--[[User:Spuck|Spuck]] 11:29, 4 December 2007 (PST) Jennifer, I'll need to see the log of your hours sometime before friday.  Also, why don't you type up the notes from our discussion and get them posted on to the galaxy classification board.  You can make the graphics in paint, or draw and scan them in, or use a digital camera to take pics of your notes and upload the graphics.  Either way is fine with me.

Jennifer, again, good job on posting, but please post in the Galaxy section, if you need a refresher on how to get to it, from the main page go to Future Research Projects and then from there Galaxy then discussion. I beleive that is the route.
--[[User:Spuck|Spuck]] 11:25, 4 December 2007 (PST)  FYI ... here is the link again to the Go to the discussion page off of the [https://coolwiki.ipac.caltech.edu/index.php/Galaxy_Classification Galaxy Clasification Page].

--[[User:Danielle|Dani]] 10:53, 4 December 2007 (PST)When posting, rather than typing your name and time, simply click the icon above the Subject/Headling square that looks like a squiggle. It is the second icon from the right. Click that before you start your post, it will post your name date and time for you. and then at the end of the post, simply type [end]

--[[User:Nicholas|NicholasJamesKelley]] 10:17, 7 December 2007 (PST) Perth is down at the moment and has been for a couple of days and will continue to be for an indefinite period of time. This is a very depressing bit of info because it not only sets back the spitzer project as a whole but also sets back my and other individual's projects for the Pittsburgh Regional Science and Engineering Fair.
== Light Curve Correction ==
--[[User:Danielle|DanielleYeager]] 10:44, 7 December 2007 (PST) In study of both Nick's and my own light curve, we have discovered why the peaks are not matching up. The graphs show two different candidates rather than two different filters for the same candidate. Both light curves need redone, focusing on one candidate in both the I and the R filters. Each graph needs to show the I and R light curve for one candidate. [end]
--[[User:Nicholas|NicholasJamesKelley]] 10:47, 7 December 2007 (PST) These are my light curves for the 2 candidates that I am monitoring for Spitzer and the Sceince fair. I am currently monitoring to get more accurate curves to take with me.

--[[User:Nicholas|NicholasJamesKelley]] 10:13, 11 December 2007 (PST) Perth is still down and therefore we have decided to try and make the switch to New Mexico Skies to finish collecting data to get better light curves.
