C/2012 X1 (LINEAR) - Comet

C/2012 X1 (LINEAR) 
(Passing through starfield in 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.

Evening Session

 Nova Delphini 2013 - nova

Nova Delphini 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

The image below was taken 80 days after discovery when nova had faded to around +10.6
The Nova is the central object in the image.

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
