Mike,

If you Mark Clementine correct for question 11 when it is clearly incorrect in terms of the "strict" wording of the question, you have to mark "Comet C/1790 A1" correct for question 28. This is just being consistent as the scenarios surrounding both questions and answers are identical and yup I am saying it cause its the only 1 I got wrong

One part of one question wrong. I just went and burnt the book that gave the answer.

Rusty!!! Damn thing is petrified

I tell my students "Check your answers. Check your answers." And what do I do "I know that one

"

I am assuming that other names for Rigil Kent are accepted in question 21...

Is this reasonable to assume?

iceman (Mike) · #**146** 27-09-2005, 05:41 PM

Sorry John B, but I have to say, the Comet one was probably the most incorrectly answered one. You weren't the only one to find the 3rd comet discovery.. about 10-15 other people did as well

Scott, Rigel Kent and Alpha Centauri were both marked correct. It's perfectly reasonable to assume that

ausastronomer (John Bambury) · #**147** 27-09-2005, 05:45 PM

I think your missing my point entirely Mike, your clearly not being consistent, I couldn't give a Rats ar-- about going in the draw so take me out and mark the others correct that answered Comet C1790 A1. Or, mark Clementine incorrect for Q11 to at least be consistent.

John, if your answer was sg like "Her third DSO discovery was NGC253 and third comet discovery was C/1790 A1", then you might have some sort of a case. Otherwise no prizes for you!

# What was the third discovery of Caroline Herschel?

A: NGC253 (on 23/09/1783). Comet C/1790 A1 (in 1790) is not correct, that was her third comet discovery, but not her third discovery.

Damn.

I blame Greg Bryant

Quote:

Comet C/1790 A1 (Herschel)
Caroline's third discovery came on 7th January 1790, with the new comet being reported at a brightness of 7th magnitude. The comet's apparition was quite poor, being seen only on three other days, the last being 21st January. Two days beforehand, Charles Messier described the comet as nebulous with a bright condensation, and compared the comet's brightness to Pegasus' globular cluster M15. On the basis of the observations available, perihelion occurred on 15th January at 0.76 AU.

ohhhhhhhh

missed out on 28.. the comet one also.. DOH!

got spot on for everything else.

janoskiss (Steve H) · #**151** 27-09-2005, 06:13 PM

Don't blame Greg, Phil. You've got to read the passage you quoted in context. Early in the article we read "Herschel's first comet discovery came on the night of 1st August, 1786".

But I don't think NGC 253 is correct either. There are webpages saying so, but if you look at the records there is a enough ambiguity that any one of around 10 or so objects might have actually been the third discovery.

http://cometography.com/biographies/herschelc.html

I believe the above article is so definite about NGC 253 being the third because it's easier to tell (make up) the story in this way. First this happened on this date, second this on that date and third another thing on another definite date. Bang, bang, bang. Now that sounds really convincing, and makes the author sound like they know their stuff. But if they honestly said that there were these dozen or so early discoveries in 1783, a few of which we have exact dates for, but most of which we don't know exactly when, and some of those might not really have happened at all, or might have happened later or were due to someone else, and there is some conflicting data and ambiguities in the historical records and so on; that sort of thing is much harder to narrate.

www.seds.org has the facts on C. Herschel along with useful references.

iceman (Mike) · #**152** 27-09-2005, 06:39 PM

John, I did not mark Clementine correct, as Steve has pointed out. I only marked it correct where someone had the answer something like "Clementine and then Lunar Prospector".

Only 2 people (I think) put Clementine on it's own, and they were marked wrong.

h0ughy (David) · #**153** 27-09-2005, 07:15 PM

Hey Mike, I did a stupid thing and didnt keep a copy of what I sent you, can you send my PM of the answers I gave back to me?

janoskiss (Steve H) · #**154** 27-09-2005, 07:18 PM

Isn't it in your PM Sent folder, Houghy?

Out of pure curiosity only. Which PN is actually the largest of the other 3 mentioned ?

Mike,

Then I have no issues.

You said in your earlier post, " If you put 'Clementine' you were marked correct" which I did have issue with because its not the correct answer to the question that was asked.

Slice,

I am not sure which is the actual correct answer.

I put Sharpless 2-216 which has an angular size of 1.6 degrees. PG1034+001 which has only recently been discovered has an angular size of almost 2 degrees. The Helix has an angular size of 16' (that depends on which source you check). The Helix is generally regarded as the largest visible in amateur telescopes but as they grow that no longer really holds true as Sharpless 2-216 is visible in scopes over 16" aperture under pristine conditions.

By the sound of the confusion, I'm glad I didn't enter LOL!!! On the page before this one someone mentioned that maybe people didn't enter because the questions looked too hard. BINGO!

I am one of those. I really didn't feel like spending endless hours googling all the answers. But I am glad others had fun doing it.
