was just looking through the new candidate updates of the NTPC and A few of the candidates look promising. I am going to list the candidates in what looks like a pattern, maybe orbital. Just zoom in to see what I mean: Candidate 1) Skyplot: Metacandidate at RA: 19.007812 Dec: 1.734805 Candidate 5) Skyplot: Metacandidate at RA: 19.007812 Dec: 1.697487 Candidate 2) Skyplot: Metacandidate at RA: 19.006348 Dec: 1.716146 I have not looked at all of the new candidates yet (as of this post) But since the NTPC hasn't posted a new thread to 'discuss' the candidates yet, I figured I would start one here. There is a star in the plot, and the 'signal(s)' appear to follow something not visible (at least on the pages above), but at the same time appear to follow an almost elliptical pattern (oval-ish) around that star. I am not sure how to plug coordinates like these into Google earth/sky to get a better look, but am willing to learn if anyone is willing to explain. Anyways...thoughts on the above 3? "By faith we understand that the universe was formed at God's command, so that what is seen was not made out of what was visible". Hebrews 11.3 |

how do you identify those coordinates for those stars in the sky map, i allways seem to get it wrong |

I was hoping I could be taught :P "By faith we understand that the universe was formed at God's command, so that what is seen was not made out of what was visible". Hebrews 11.3 |

I have no idea how to convert the RA/DEC into hours, minutes and seconds. I was hoping I could be taught :P Most scientific calculators (whether stand-alone or implemented as computer software) have a function for that. But it’s pretty easy to do step-by-step as well: A. The digits in front of the decimal point represent the hours of RA or the degrees of Dec. B. Multiply the rest of the number, from the decimal point on, by 60. The digits in front of the decimal represent the minutes. C. Subtract this value (i.e. discard the integer part again), then multiply the difference by 60; the result is the seconds (with decimals). Example: RA 19.007812 A. 19 h B. 60 * .007812 = 0.46872: 0 m C. 60 * .46872 = 28.123 Converted: 19h00m28.123s Example: Dec. +1.734805 A. 1° B. 60 * .734805 = 44.0883: 44' C. 60 * .0883 = 5.30 Converted: 1°44'05.30" N. |

I was hoping I could be taught :P The DEC still, according to Google sky, needs to be DD:MM:SS "By faith we understand that the universe was formed at God's command, so that what is seen was not made out of what was visible".

Well assuming I used this calculator right, Wikisky shows nothing there, or at least nothing visible. There might be a glimpse of something in the 1st or 2nd link, but I suspect it might be just an artifact of zooming/focus etc. I do like to note though that it showed up in 3 different places around that particular star, on at least 3 of the candidates. EDIT: Most of the candidates follow something around that star. If those calculation above are correct anyways. It looks like they follow a circle around it or at least an oval. Any insight as to what star that is? EDIT: Wikisky says it's: HD 176488 "By faith we understand that the universe was formed at God's command, so that what is seen was not made out of what was visible". Hebrews 11.3 |

the coordinates for the WOW signal, how would that convert then, Right ascension (on the positive horn): 19h25m31s +/- 10s Right ascension (on the negative horn): 19h28m22s +/- 10s Declination (the same for both horns): -26d57m +/- 20m |

Convert to what? Those coordinates are already in sexagesimal format, which is what the earlier posting was about. Are they given for a standard equinox (e.g. J2000)? Or are they for the equinox of the date of the observation? In the latter case they can be converted to a standard reference, or into ecliptic or galactic coordinates, for that matter—but all conversions need both a “from†and a “toâ€. |

Wikisky says it's: HD 176488 Plugging the first pair of figures into SIMBAD’s coordinate query (note that it’s quite flexible about the input format!) turns up that one, 1.2 arc-minutes away, and a fainter one, BD+01 3848, at 2.0'. A third object in the immediate area is the unidentified infrared source IRAS 18578+0140, at just 0.8'. None of these listings show parallax data, so we can’t tell how far away the objects are, although the entry for HD 176488 gives a spectral type (K2), on which one could base a guesstimate, together with the apparent magnitude. |

Wikisky says it's: HD 176488 Hm...Interesting that it's an infrared source though. Looking at the Wikisky map of IRAS 18578+0140 (which is found by entering it into the search box) using the infrared viewer (select the map type to view by clicking the DSS icon at the top of the map) doesn't seem to show much of anything aside from a bright orange screen. When zooming out you can see various infrared images, but doesn't appear to be anything there...at least from what Wikisky shows. Invisible source? Or could it be something the star is giving off? Or maybe an object behind the star? Interesting indeed. EDIT: Also a note: From looking at the NTPC candidates, none of them even go that close to the star itself.

Also...I am wondering if there are any recent maps of the sky. It seems Google and Wikisky use data that is quite old. Is there anything that has as close to real time data?

Where would this location be in the sky in terms of constelations 13dc10ad.16736.2930.12.10.93_0 |

Where would this location be in the sky in terms of constelations Need more info from the work unit. 13dc = December 13; 10 = 2010 Need the RA and DEC which, assuming you did not finish the Work Unit, can be seen in the graphics.

23hr 6'43'RA+8deg 51' 59'Dec That’s in Pegasus, just north of its east-west border with Pisces. |

thank you for information, any know stars in pegasus with exoplanets? |

Seven stars in Pegasus are typically mentioned as having exoplanets. Unfortunately, none are anywhere near the coordinates 23 h 6' 43"/ +8d 51' 59". In case these should still be of interest they are: 51 Pegasi b; HAT p 8b; WASP 10b; HD209458 b; Fomalhaut b (HR 8799); HR8799 b, c, d; and V 391 pegasi b. All are referenced on the internet. The Wikipedia entries are useful as much of the information is given in tabular form on the right hand side of the page, near the beginning of the articles. Michael |

7hr 11' 42'' RA, +33deg 41' 20'' Dec. I fear I did the calculations wrong. "By faith we understand that the universe was formed at God's command, so that what is seen was not made out of what was visible". Hebrews 11.3 |

7hr 11' 42'' RA, +33deg 41' 20'' Dec. I fear I did the calculations wrong. What calculations? But if you’re asking where that is, it’s in northern Gemini, about halfway between Castor and Theta Gem, near the northern limit of Arecibo’s view. |
