C/2012 X1 (LINEAR) - Comet

C/2012 X1 (LINEAR) - 2013-11-01 (passing through Coma Berenicies) Sun Distance 2.18 AU Located around 450 million km from Earth, Comet C/2012 X1 (LINEAR) has undergone an explosive eruption sometime around  21st Oct (2013-10-21). Amateur astronomers report that it underwent a 100-fold increase in the comet's brightness  compared to its predicted brightness.  (Spaceweather.com  page for 2013-10-22) The comet's atmosphere or "coma" now resembles that of exploding Comet 17P/Holmes in 2007.   Image below was taken  2013-11-01 (Conditions : early morning sky)

Keid - Triple Star

Keid (Eridanus)  Keid is a triple star system located around 16.5 ly away. Star A (a main sequence orange-red dwarf) was discovered by William Herschel in 1783.  Stars BC was discovered to be a binary pair by Struve in 1851.  Star B was the first white dwarf to be discovered in 1910. Star C is a dim red dwarf. Star A and the binary pair BC have a wide separation of about 418 AUs and  an orbital period of some 8,000 years.  The B and C pair of stars have an "average"  separation of about 35 AUs in a highly elliptical orbit  that lasts about 252 years

 Nova Delphini 2013 - Nova (V339 Del)

Nova Del 2013 (Delphinus) Nova Delphini was discovered on 14th August 2013 by Japanese observer Koichi Itagaki at magnitude +6.8.  Koichi had imaged the same field the day before and nothing was visible at the same location. The progenitor star was identified from archive images as being magnitude +16.9 Alias:  V339 Del
