Re: NEOCP object A11nyuL

Forgot to add: image was taken on May 25.13 UT.

Dear all,

?

Here is one of the images I obtained last night from LCO-SAAO. 180-second exposure with a 35-cm Cassegrain; cropped, but otherwise no processing.

?

I have another set of images ordered up for tonight.

Dear Krisztian, Med, all,

?

It¡¯s still quite early in the game, but, indeed, this object does look interesting. There does seem to be some similarity to the orbit of the Daylight Comet of 1910, although the difference in the ascending node (as of right now, anyway), would seem to preclude a relationship. But, we¡¯ll see what the future holds . . .

?

I succeeded in getting some images last night via LCO-SAAO. The appearance is almost stellar, although it does seem to be slightly diffuse when compared with stars of similar brightness. I¡¯ve reported it to the MPC (and CBAT) as a ¡°possible¡± comet.

?

If something like the present orbit holds, the post-perihelion viewing geometry (when there would likely be the most dust tail development) favors the northern hemisphere. For a while, the phase angle is somewhat high, so possibly some dust tail (if there is one) enhancement from forward scattering. And ¨C yea! ¨C it¡¯s in the evening sky. On the other hand, with this small a perihelion distance, it would have to survive perihelion to put on any kind of show, and that is always problematical.

?

Again, we¡¯ll just have to wait and see. I¡¯ll probably try imaging it again in a day or so.

Sincerely,

Alan

Hello all ,

?

I know it's still too early to ask this, as the data is still uncertain, and I might be overstepping into something I don't fully understand, but I just realized that this object shares almost the same orbital elements with the Great Comet of 1910. Can you please confirm this?

?

Thanks,

Med

Hi Folks,

What do you think about NEOCP object A11nyuL, which is a possible small perihelion distance comet?

Thanks,
