Talk:IC 2118 Current Research Activities

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

-Nick-

    First attempt to take an image using Perth Failed Due to Weather. 10/17/07

X-Dani-

My targets are

     : 409 RA- 76.854562 5hr7min25.1sec  DEC- -6.238076 -6d14m17.1s R Mag17.3

TUTORIAL QUESTIONS

X-Dani-

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... "Process Completed There was a problem with the JPEG preview. See the console log for details. You can go to the logs area to look at or download the run log for this acquisition. Current Status RA Dec Az Alt 09:26:55 -60°00'03" 146° 27°

Run Journal/Log Output The script failed. Reasons may include.......

1) Its daytime!!! (Perth is GMT + 8 hours) 2) The weather conditions are not sufficient for observing 3) The script was aborted by the user 4) The slew coordinates drifted below the horizon 5) The scope, camera or both are not connected 6) REQUEST ABORTED BY ACP

You can see the dome through our sky camera at ..... http://www.perthobservatory.wa.gov.au/information/po_sky_camera.html

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.

15:22EST

mr.spuck saved a file into the practice folder showing 13 reference points. i'm going to have to go back into my data and force HOU to spit out that information.

11/21/2007

Today perth was unable to image my targets due to wind, and then later due to the fact the telescope was already in use. Nick

GRAPH IS IMAGE LOADED INTO PHOTOBUCKET.COM AND THEN SAVED TO THE WIKI AS GRAPH.JPG.... THIS IS THE ONLY SOLUTION I COULD COME UP WITH AS TO POSTING A PICTURE OF THE GRAPH. ANY IDEAS OR OTHER OPTIONS??

.......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.

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 desire goal.
