-
attempt at variables of lowly altitude on southern
meridian.
-
V553 Cen [at -32o Dec] eg F4-K01 type a surprisingly
good spectral profile match for R Pup [G2] and U Pyx [K5].
-
R Crv at min mag <13 [via AAVSO webpage] is an
IR emitter like R
Cnc, R Leo, o
Cet [Mira].
-
R Crv fieldstar GSC 6105:1025 [mag 9.2 at -19o
Dec] obviously M-type at download and spectral match with SW Vir.
-
First spectrum of C/2001 Q4 [NEAT] shows just reflected
yellow sunlight. G5 [yellow] + A5 [white] stars for comparison.
-
experiment with 30o prism before 135mm
fl f/2.8 lens + HX5 CCD with profiles via AstroArt. Lens chromatic
aberration seen in fishtail flare in near IR/UV.
-
V Her 04 - bland spectrum [no obvious emission or
absorption lines] of new CV? variable. Blue object [LH slope] with
AK Cep [F6-G2] a fair match..
-
V1316 Cyg [UGSU type] reported to brighten 2004 late
June but faded to ~m17 before spectrum could be obtained.
