NGC2264 - Knoll Observatory EMAIL to AAVSO 01/21/2004


Comparing an image I took last year of the "Cone" Nebula, I noticed a star just above and to the left (about 11 o'clock) of SAO114264 in the image from 12/07/2002. The same star is just barely visible in last Saturday's (01/17/2004) image. The images were taken using a 10 inch LX200 and a ST7e at f/3.3.

I researched images around the internet and found that the star is visible in some and barely or not visible in others. Would definitely be interested in comments.

Hi, Pat.

I think the star you are noticing is V582 Mon, an "Orion Variable" associated with the nebulosity in the Cone Nebula (likely a very young star). If you are interested you could monitor the star closely for about a year and build a light curve to try and identify its type. That would preferably be done with a Johnson V filter but since you don't have any I would observe it unfiltered. If you get a light curve let us know and we'll add the data to our database and see if there is a place to get it published (much depends on the quality of data you are able to get).

Clear skies!
