Re: (meteorobs) More Questions, RA,Decl
Yup, John, I think you've got the hang of it! (I get RA 17 DE +61 as being just
over a degree East of gamma Cas, the middlemost star of the "W".)
But to save you some work for future meteor watches, check out the IMO Web
site, and especially their concise "Meteor Calendar" at:
http://www.imodot net/calendar/cal98.html
At the bottom of that calendar is a neat table showing all the active showers
for any time of this year, and what their radiant positions are. Here's an
excerpt from that table for the next month or so:
IMO Active Radiants during 1998:
Jun 30 CAP JPE
Jul 5 285 -16 SDA 338 +14
Jul 10 PHE 289 -15 325 -19 NDA 341 +15 PER PAU
Jul 15 032 -48 294 -14 329 -19 316 -10 012 +51 330 -34
Jul 20 299 -12 333 -18 319 -9 SIA 018 +52 334 -33
Jul 25 303 -11 337 -17 323 -9 322 -17 023 +54 338 -31

Aug 25 288 +60 332 -5 076 +42 347 -2 065 +60
Aug 30 289 +60 337 -5 082 +42 DAU
Sep 5 088 +42 055 +46 SPI
NOTE this table uses the IMO "3-letter codes" for showers, e.g.,
Pegasids JPE
July Phoenicids PHE
Pisces Austrinids PAU
Southern delta-Aquarids SDA
alpha-Capricornids CAP
Southern iota-Aquarids SIA
Northern delta-Aquarids NDA
Perseids PER
kappa-Cygnids KCG
Northern iota-Aquarids NIA
alpha-Aurigids AUR
delta-Aurigids DAU
Clear skies!
