(meteorobs) Abbreviated 2015 Orionid max...

Hi Paul, Norman,

Don't forget to tell the people about your higher radiant altitude ;-) 

If I would have 25 ORI's  in the last hour before dawn; it would be more thana  normal return  (at least when I am talking about the 2015 event...)  I'm observing from 50° North. 

So far for the Orionids: the weather wasn't cooperative at all...  Only one 3-hour session in the morning of October 21th. I observed 26 Orionids (hourly counts 7-9-10 with a declining limited magnitude 6.3 till 6.1). But I saw some nice onces inluding a -5 fireball! 

My greatest ORI return so far: 2007! 5 clear nights in a row starting with October 20-21 till 24-25... more than 700 Orionids observed!! 


Norman: never thought about starting some video observations, for exemple the CAMS project from dr Peter Jenniskens??


Kind regards, 


Michel

Good to hear from you Norman and I hope you're right about the ORIs.  I plan to check it out this year.  I don't think I've ever watched them for five straight nights before but I do know that they have quite a plateau maximum for sure.  Our weather here in north Florida has been very uncooperative this year so far for the ORIs, but I did manage to get in two disjoined hours of watching this morning (Oct 21/22) and had 25 ORIs in the last hour before dawn with fog degradation.  The majority of them were quite faint, for sure.  More complete report to follow.   
Sorry to hear of the perception problems, I worry about that quite often myself.  So far anyway, I seem to have kept at least enough of mine to be able to hang in there which amazes me with all the computer-related work I've done.  So far anyway, it has been only my close-up vision that has been hammered and my glasses correct that.  I don't need or use them at all when I am out meteor watching.  They have horrible spherical aberration and double most of the star images anyway...;o).  They are totally useless for meteor watching.
Clear skies, Paul J in north Florida

Only three?  In my active times I found the Orionid maximum lasting for
five nights.  Just as strong on the morning of October 25 as October
21.  On October 26 it would be cut in half.



My last attempt at meteor observing was 3 years ago.  I went out east
of town to somebody's semi dark-sky house location for the 2012
Orionids.  A decent sky with LM 6.5.  I still saw the brightest Messier
open clusters as resolved naked-eye.  The session October 21 was to
cover 3 hours before dawn.  But I had to wait half an hour before
seeing the first meteor!  The date was a memorable night in numerous
prior years, so it was disconcerting to see almost nothing.  I quit
after an hour and a half with only 12 meteors, mostly Orionids and
absent all of the faint ones.  That night confirmed that my perception
for meteors is largely gone.  So it is no longer worthwhile for me to
pursue meteor observing.



The first hint of a problem came for the 2012 Perseids from the same
location.  In just over an hour starting around 2 A.M. I saw only 9
Perseids, and almost nothing fainter than magnitude 2.  So I quit
earlier than planned that night also.



Speaking of faint meteors, I found the Delta Aquarids to be tied with
the Orionids for the rank of faintest shower.  Around 20 years ago I
received a call from the local newspaper.  Somebody got wind of a
meteor shower due at the end of July, so he wanted to stump up a story
about the usual fiery show of meteors but at an unusual time.  I
recommended that he cancel any such story.  People in town would be
lucky to see anything at all.
