What a night!
by Patrick Wiggins 16 May '05

16 May '05

What a great night we had at SPOC tonight. As if excellent views of the planets and several NGC objects weren't enough, we had a nice ISS pass, a -7(!) Iridium flare and capped it off with a very nice auoral display (that continues even as I type this). No doubt we'll pay for this good fortune with 6 more weeks of bad weather... Patrick :-)

At 01:00 AM UTC 05/15/2005, I arrived at my OP (Little Mountain Pass, 10 miles east of Salt Lake City, Utah, Latitude N 40.8, Longitude W 111.9) to find the auroral display had already begun. This display was principally a continuous faint homogenous Type C (green) skyglow along the northern horizon from W 20° to N 0° to E 70° between 0° and 30° altitude. Through the course of display, the homogenous glow would partially coalesce into faint discrete rayed arcs. Unusually, Type C skyglow patches formed between 15° to the zenith (90°) in altitude. These lasted between 30-45 secs, with occassional patches lasting for 75 secs. Type C green aurora are caused by highly excited oxygen at 100-200 km above the surface. Only one instance of faint Type D (red) streaking was seen at the far W 20° azimuth. During part of the display, homogenous Type C arcs started to form on the northern horizon. From the 5-10° angle between the north horizon and the base of these proto-arcs, it was estimated the main auroral band was about 1100 kilometers (685 miles) north of N 41° latitude on the U.S. Canadian border at N 46° latitude. Brightness varied from International Brightness Codes I (IBC I equal in brightness to the Milky Way) to IBC II (brightness equal to a moonlight cumulus cloud). For comparison, the contrast between the Aquila dark clouds and the Milky Way disk was visible in the south-east sky. Cassiopeia was rising in the bright glow band along the northern horizon. The principal stars of the constellation figure (alf-del Cas) were visible with eps Cas (3.4v) representing a boundary between the visible and secondary invisible Cas stars like zet Cas (3.6v) and iot Cas (4.5v). One diffuse skyglow patch formed directly over over Lyra. Alf Lyr (Vega, 0.0v) was clearly visible, while gam Lyr (3.2v) and bet Lyr (3.4v) were not. Although fainter and more diffuse than prior aurora seen at this low-latitude site, the unique feature of this display was its total extended duration with multiple transitions. The display lasted about two and one-half hours. The display repeatedly faded in and out. A draft of my full observing log is at: http://members.csolutions.net/fisherka/astronote/observed/CME200505/CME2005… I shot a roll of 35mm film. If any pictures come out, I'll post them at a later time. - Canopus56 (Kurt) Yahoo! Mail Stay connected, organized, and protected. Take the tour: http://tour.mail.yahoo.com/mailtour.html

Space Weather News for May 14, 2005 http://spaceweather.com A coronal mass ejection (CME) is heading for Earth following a strong solar flare on May 13th. Sky watchers should be alert for auroras when the cloud arrives on May 14th or 15th. The display, if it materializes, will be best over high latitudes--e.g., Alaska and Canada. But CMEs sometimes spark auroras over lower latitudes, too, so everyone should keep an eye on the sky this weekend. Visit http://spaceweather.com for updates.

Re: RE: [Utah-astronomy] Stinkin' birds (was Scientists BoycottEvolutionHearings)

There is a simpler solution. We have a barking beagle here who loves to chase cats and birds. All we have to say is "get the birdy" and he will scare them out of our yard. It is really fun to watch by the way. In the summer, he is also called the "bug patrol" because he likes to kill cockroaches.

Hi Wayne, It would probably take care of the birds but it would also require the building of that new observatory that Michael spoke about. <g> So, it would probably get the -wife- veto. -----Original Message----- From: utah-astronomy-bounces+dale.hooper=sdl.usu.edu(a)mailman.xmission.com [mailto:utah-astronomy-bounces+dale.hooper=sdl.usu.edu@mailman.xmission. com]On Behalf Of Wayne Sent: Thursday, May 12, 2005 2:14 PM To: 'Utah Astronomy' Subject: RE: [Utah-astronomy] Stinkin' birds (was Scientists BoycottEvolutionHearings) Would a potato cannon barrage help?
