RE: [APML] Comet IZ & M31 [was: Comet IZ from Arizona]
I'm getting the same 22 degrees separation for IZ and C/2002 F1 from SkyMap,
but I noticed C/2002 E2 (Snyder Murakami) lurking in Vulpecula. (Updated CfA
ephemeris data today.)
IZ and Snyder Murakami will be less than 3 degrees apart on April 30, with
predicted mags of 5.3 and 10.8 respectively. Both will be circumpolar with
minimum altitude of about 10 degrees (for Latitude 41 degrees (Chicago))
near 6pm (daylight time) (2300 UT). Transit is around 05:40 - 05:45. (1040
UT)
