Hi,

There's a comet beginning to make an appearance for northern hemisphere observers--it might become a bright one. I made this sketch and observation early this AM and posted it in the Solar System and Planetary Observing forum.

I worked with HB and 2B pencils and a stump on white Artagain sketch paper and inverted things digitally (also applied 5% blur).

It was cold and I can't sketch with gloves usually, so I kept a HotHands chemical warmer in the muff I wear around my midsection and was able to keep my fingers functioning.

Let me know what you think. :)

Michael,

Very nice sketch of this early morning comet. :bow: :cool: Your techniques always impress me and work so very well. I know what you mean about sketching in the cold, below 25 degrees F I start having trouble with numb fingers. This comet will be fun to follow.

Frank :)

Frank, Brad--thank you very much. I'd like to make several observations of C/2007 N3 but you never know about comets--this one might fizzle (hope not).

Frank, try the handwarmers--it's really nice to have something hot to grab onto when your hands start to chill and it puts the feeling right back into my fingers.

Happy New Year, everyone!

Michael,

An excellent observation of this interesting new comet. I hope that it does brighten for all of us to follow it. Thank you for sharing it with us all.

Happy New Year!

Thanks, T5. In my advancing old age, it seem to be easier for me to get up early than to stay up late... ;)

I took another look at our icy visitor from the outer reaches of the solar system and made this update to my sketch.

Thanks, Carlos. I'd like to see your take on this comet. :)

I made a new observation and sketch this morning posted here. Media were the same.

Very nice sketch! :bow: :bow: :bow: I just posted to another link with your sketch where Rev Aaron had started the post to alert observers. It looks as if from projected charts that the comet could reach peak brighteness in February as it moves from Virgo toward Leo and close to Saturn.

I noticed that it is difficult to find dates or RA ~ DEC on comet posts in the web as I am always curious to know, where exactly is it in the sky currently? And why no dates in these sites? I would think that astronomers would be the most astute about posting dates especially as comets positions change constantly. The three sites that Carlos listed are useful though; Thanks Carlos!

I found a nice rough and fine charts but again no dates >

Thanks again to all for the heads up; I'll look forward to observing the comet, as weather permits,

Hi Mark,

If you go to this Ephemeris site
http://www.cfa.harva...ets/2007N3.html you will find below the orbital elements a good Ephemeris which includes RA and Dec for selected dates throughout the year. Using a transparent film you can plot these on your favorite star chart for locating on any date by extrapolation. The Heavens above site you copied above gives the coordinates for the date and time you are looking. Look at the data under the first image. I hope this helps.

Frank :)

Michael,

Nice update to the sketch sequence you have started. I may need to wait a few more days to get a clear morning and a look for myself. Keep going if you can. :bow: :cool:

Frank :)

Thanks, Mark. The charts posted on Heavens Above are for the current day you view the chart. I posted a link on the Planetary and Solar System Observing forum to another chart that will take you through January 31st. Good luck!

Frank, thanks for the encouragement. I hope you get the weather and opportunity to see Comet Lulin soon. The Moon will shortly become a limiting factor, but after that, Lulin will be higher in the sky and hopefully brighter.

Ed,

Not only is that an excellent sketch, you have given me a new target to look for (providing the clouds go away).

Thank you, Wade. I hope you get a chance to go for this comet. The Moon won't be a factor for a couple more days if you can catch a clear morning and don't mind getting up with the chickens. ;)

Hi,

I posted a new sketch of Comet Lulin done with 2B and HB pencils and a stump and inverted.

The moon is out of the picture now so it's a good time to go comet chasing. :)

Michael,

Another fine sketch of this morning comet. Tried to catch it the last 3 morning but all three were cloudy. Eventually I'll get a look. Thank you for posting your excellent capture here. :bow:

Frank and others

Thanks for the Ephemeris on Comet Lulin. It has taken me three weeks to get back to this post to catch up on responses!

I've been lost in space and so many other things lately.

Thanks, Frank. The comet's getting better so don't worry about clouds making you miss anything. ;)

Michael,

Thank you for your excellent observation of Comet Lulin. This is an interesting comet to follow. I hope to be able to observe it soon myself. I look forward to your future observations.

Rony, Carlos, thank you much. :) Hope to see your comet observations soon. It might clear here over the weekend and allow me another look.

Thanks, T5. Drag yourself out of bed and take a look--binoculars will do the trick. :cool:

I made a new observation and sketch this morning (Feb. 1st). The sketch is here. This drawing was done indoors with HB and 2B pencils and a stump from observing notes and then inverted digitally.
