(meteorobs) Fwd: meteorobs-digest V1 #234




There were indications that some of you didn't receive this, so here it is 
again! Clear skies,

Subject: Re: (meteorobs) geminid max

I agree with Norman on the Geminids being my favorite meteor shower. I have
observed this meteor shower more than any other thanks to the crystal clear
(and cold) Decembers in my region. The rates are very consistent from year
to year and the darker skies enable the colors to almost jump out at you! I
will admit I do like the Perseids as well, but August in the St. Louis area
is usually inflicted with heat and high humidity levels. The LM's are
rarely better than 5.5 and it is rather uncomfortable. Since I began
seriously observing meteors in 1974 I have had only three occasions where
unusually clear skies were present on the night of the Perseid maximum.

Subject: (meteorobs) Who to call for Discovery?

By any chance does anyone on this list know a phone number to call if an
astronomical discovery is made? Bob and I often thought about having a phone
number available at my observatory just in case we see something like a Nova
or Supernova while observing meteors. I have Brian Marsden's email address
for such an event, but I won't have access to my computer while observing.
bob has a cellular phone out there ...so....a phone number is what I want to
have on hand. Thanks!

I have experianced the same thing with the Perseids. This is why I would say
that this years' Leonids was equal to the best Perseid maxima I have seen,
with the exception of the 1967 Perseids when I saw about 100 ZHR

Subject: Re: (meteorobs) Who to call for Discovery?  

George's idea is a REALLY good one, actually! Remember that SN 1987A in the 
Large Magellanic Cloud wasn't discovered (photographically) till it reached *5th 
magnitude* (about 12 hours after it first reached 10th magnitude :>).

Unfortunately, a look over the Web site of the "Central Bureau of Astronomical 
Telegrams" revealed that they DON'T provide a phone number for reporting 
discoveries (comets, supernovae, novae, asteroids, etc). Instead, they want to 
receive postal mail, or preferrably e-mail or a Web-form report! The email 
address is:
	cbat@cfa.harvarddot edu
or else a Web discovery form can be filled out at:
	http://cfa-www.harvarddot edu/cfa/ps/DiscoveryForm.html

Now George, if you find a supernova in our galaxy with your eyes before I find 
one in an external galaxy with my scope, I'll never forgive you! :)


By the way, here's an excerpt from the "International Supernova Network" Web 
page. Not all of it is applicable to an INTRA-galactic visual SN discovery, but 
these are good verification procedures to consider anyway. Anyway, IF you follow 
all the applicable steps below, and you still believe you've found something, my 
advice is to drive to the nearest computer and send a report! Otherwise, maybe 
some of the subscribers to 'meteorobs' can exchange home numbers, and if one of 
us sees something, some of the others can access their computers, check the 
object, and perhaps send out a report.

Should you spot a suspect star while hunting for SNe...

(1) You should check all archive references you have in your library or on your 
PC [for a list of atlases and galaxy charts please see  bibliography] 
(2a) You should check for possible asteroids using commercially available 
programs... [i.e.: Megastar, Guide, etc.] 
(2b) or by checking for motion [wait for at least an hour since first 
observation] 
(4) You should check for a possible variable star 
(5) You should obtain an image of the galaxy, using your equipment or help from 
other amateurs [a digital image is great!] 
(6) You should check your records for the previous observations of the same 
galaxy [when was the last time you observed?] 
(7) You should check AND double check the suspect star approximate offset from 
the nucleus
(8) You should estimate approximate magnitude of suspect star and limiting 
magnitude of your equipment [an error of +/- half a magnitude is ok if you can't 
do photometry] 
(9) You should ALWAYS take a second look or a second image of the suspect star. 


If you STILL think you've found a supernova.... If you did all steps (1) to 
(9).... AND you are still 100% convinced that it could be a supernova.... 

THEN you can use this form[Web link] to report the suspect star to the ISN 
mailing list followed, if you wish, by a short  message, AND you can send a 
message to the International Astronomical Bureau. 

[ALWAYS include in your message name and address, equipment used, date of 
observation, galaxy, offset from nucleus, magnitude, what did you do and
didn't do to check the suspect star and date of previous observation].

The interesting thing about the Central Bureau is that they seem to
recommend that discoveries are announced through e-mail channels, but there
are three phone numbers that are given on the current issues of the IAU
Circulars, which used to be the main numbers recommended for discovery
announcements. In fact, the Circulars note that they should be used for
emergencies only. They are

(617) 495-7244
(617) 495-7440
(617) 495-7444

Hope this helps, George!

Subject: (meteorobs) NAMN Meteor Report: Nov 16/17(Assmus)

     Here are the full results of my observations on Non 16/17, 1996 during
  the peak night of this year's LEONIDs.  I have previously calculated ZHRs
  and they have appeared in a separate post.  Also, I modified somewhat the
  NAMN e,mail  report form.  (no speed estimates nor plotting was done. Hope
  that's ok with you Mark.)  Included instead are a column for noted color and
  whether the meteor seen had a wake or a persistent train (pt).  If a
  persistent train was noted, the duration in seconds is given.

                        (43%)  (57%)

  I calculated a Spearman Rank Corr Coeff (no distributional assumptions)
 between the magnitude and wake/pt.

                        Spearman r =  - 0.65066

   At least for the Leonids, there is sig relation between apparent brightness
 of a meteor and whether or not you see a wake or pt.  In Lovell's book
 "Meteor Astronomy" he discusses this, so I thought I go ahead see what my
 data show.

Well, Norm,

     Thank you for your comments.  First, let me say, Bob has told me that
  you are possibly one of the most experienced and senior meteor observers on
  this list (if not in the USA) so I greatly appreciate your time to look at
  my post and respond.  Though I'm still debating how helpful "lets get real"
  and "that's not the way it was!" are as scientific criticism.

     In the presentation of our data, I made no claims of "These data
  reflect the way it REALLY was".  I presented our observational results and
  clearly indicated using the methodology as outlined in the 1994
  Jenniskens paper.  Seems like you really don't have issue with our data,
  rather you have clear problems with the rationale and development of ZHR
  calcs as outlined by Dr Jennisken's.  I agree with your criticism of the
  overcorrecting for lower radiant elavtions.  None of our calcs were done
  with radiant lower than 10deg.  I also have a problem, as you do, with what
  happens to ZHR calcs when sky Lm deteriorates.  In that last interval, Bob's
  Lm drops to 5.77, yet he sees 35 LEO, crank thru the formula and ZHR=67.78.
  Even considering a large SEM (11.46), I agree with you fully that this is
  suspect.  Lastly, no one answered my question with regard to Cp.  Re-reading
  parts of Lovells book from the 50s on Meteor Astronomy, I see he talks about
  a Cp but his formulation slightly differs with that from the Jennisken's
  paper (though I think the idea is similar).  Norm, what are your thoughts
  about an observer-dependent perception correction factor?

Subject: Re: (meteorobs) Who to call for Discovery?

- - -- [ From: Robert Lunsford * EMC.Ver #2.5.1 ] --

By any chance does anyone on this list know a phone number to call if an
astronomical discovery is made? Bob and I often thought about having a
phone number available at my observatory just in case we see something
like a Nova or Supernova while observing meteors. I have Brian Marsden's
email address for such an event, but I won't have access to my computer
while observing. bob has a cellular phone out there ...so....a phone
number is what I want to have on hand. Thanks! George Z.

George,

Interesting question. I keep the toll free number for the AAVSO with me
in case something like this occurs. The number is 1-800-642-3883. I will
also now include the numbers provided by Gary for the IAU.

Bob

Subject: (meteorobs) Recording Meteors

Since it takes me 60>seconds to record each meteor, I would be eaten alive 
during major showers(Geminids,Leonids)!  Here is the easiest way of recording 
meteors I have ever seen(I invented this.  I *did not* get this from someone 
else.)

I found out a year ago that my computer has a"tape recorder".  I believe it 
will record for an unlimited length.  You can store hours of recording on a 
floppy disk!

Well, in the last month or so, I have learn the basics of electronics.  For my 
family,  have made the following:a clock alarm, a doorbell, and a security 
system.  Well, for the last 10 days I have been trying to think how I could 
link meteor recording to electronics to make it easier.  

Here is my novel idea...

I attached a buzzer to my speakerphone on the computer. So, when the buzzer 
goes off, the computer records it.  I attached a transformer to the buzzer for 
electrical power.  The wire goes outside, and the operator only needs a 
switch.  When the switch goes on, the buzzer goes on, and the computer records 
it.

OPERATION
- - 
------------------------------------------------------------------------------
- - ----------------------------------------------------------
You see a mag 2 meteor,speed 2, white, 1/2 second train, which is a geminid.
- - 
------------------------------------------------------------------------------
- - ----------------------------------------------------------
1.You buzz for 5 seconds(This signals that just a few seconds ago, you saw the 
meteor.  When you go back an analyze the data, the program has a timer, so you 
can determine when the meteor occured, accurate within 5 seconds.).
2.You buzz 3 times, each interval is 1 second long(This signals 
magnitudedot below is a chart).

buzzes            mag
- - ---------------------------------
1                     0
2                     1
3                     2
4                     3
5                     4
6                     5
7                     6
8                    -1
9                    -2
10                  -3,etc.
- - --------------------------------
3.You buzz 3 times(This signals speed, using the mag scale.).
4.You buzz once(This signals color.  A sample chart is below.).

buzzes                      color
- - ----------------------------------------------------------
1                             white
2                             red
3                            orange
4                            green
5                           blue
- - ---------------------------------------------------------
5.You buzz 2 times(This signals train length, based on the chart below.).

buzzes                     length
- - --------------------------------------------------------------
1                            1/4 second
2                            1/2 second
3                            3/4 second
4                            1    second
5                            2    seconds,etc.(trains into the minutes may 
become troublesome!)
- - -----------------------------------------------------------------
6.You buzz ? times(This signals shower.  The charts will vary, of course.).
- - 
------------------------------------------------------------------------------
- - ---------------------------------------------

Please let me know what you think about this!!!
