Hi everyone,
Captured this image two nights ago while imaging Comet Atlas. I believe the trails are from a Starlink train that passed through during the 60-second exposure. There were no trails on either the image taken just before or after this one.

One of my objectives last night was to capture some RGB data on M13. ?M13 was near the meridian and I got just enough data to make a worthwhile image. ?This effort resulted in my first really good example of an RGB image. ?I also was able to get additional data for M51. ?I wanted to experiment with M13 before tackling M51.

I sent his earlier, but attach the original file which may have been too big. ?Delete that or refuse it if it comes to you.

Spectacular color image of M13, Scott.? I look forward to seeing M51 in color too!

Can' say if I’m happy with this or not. ?You tell me. ?I added 30 minutes of each channel (RGB) to the 3.5 hr M51 I took over multiple nights. ?Probably would improve with more RGB data. ?

Comet Atlas has double nucleus!
Dear MSRO and friends,
Images obtained last night with the 12-inch LX-200 show a splitting in the nucleus of Comet Atlas. It now has two definite condensations which undoubtable are a result of a major fragmentation event in the nucleus. I wonder if we will start to see two separate comets or fragments with their own dust tails in the coming days. I would encourage close observation as a lot is happening now with this comet!

That
is very cool.? I’d love to use the FRC on that comet, but I can find it
because it’s too dim.? My observatory software star charts don’t list Atlas
in the DB.? I’m not sure how accurate my SkySafari 6 Pro version is.?
I’ve tried to star hop and scan, but just can’t find it.? If you could send
R.A. and Dec coordinates blindly to me via text message periodically when you
are imaging.? That might help me find it.

Dear MSRO and friends,
Images obtained last night with the 12-inch LX-200 show a splitting in the
nucleus of Comet Atlas. It now has two definite condensations which
undoubtable are a result of a major fragmentation event in the nucleus. I
wonder if we will start to see two separate comets or fragments with their own
dust tails in the coming days. I would encourage close observation as a lot is
happening now with this comet!

Re: Comet Atlas has double nucleus!
Yes it is diffuse and faint. One of the nucleus components is still visible but the other has dissolved.?

Hi Scott,

Here is the link to the Minor Planet Center for Comet Ephemerides I created
this table based on your location
LAT: +38.17528
LON: -77.8636

You should be able to do this query in the future to get the exact RADEC
values at any time.

That
is very cool.? I’d love to use the FRC on that comet, but I can find it
because it’s too dim.? My observatory software star charts don’t list Atlas
in the DB.? I’m not sure how accurate my SkySafari 6 Pro version is.?
I’ve tried to star hop and scan, but just can’t find it.? If you could send
R.A. and Dec coordinates blindly to me via text message periodically when you
are imaging.? That might help me find it.

Dear MSRO and friends,
Images obtained last night with the 12-inch LX-200 show a splitting in the
nucleus of Comet Atlas. It now has two definite condensations which
undoubtable are a result of a major fragmentation event in the nucleus. I
wonder if we will start to see two separate comets or fragments with their own
dust tails in the coming days. I would encourage close observation as a lot is
happening now with this comet!

Comet Atlas showing nucleus fragment dissolving
Dear MSRO team and friends,
Here is a two frame animation made from stacks of exposures taken almost exactly 24 hours apart on April 21 and 22, 2020 centered on 2H UT. They show how quickly the nucleus fragments change and fade. The 12-inch LX-200 of MSRO Station 2 was used for this sequence.
Also, a special thanks to the folks in the Birmingham Astronomical Society for inviting me to participate in their virtual meeting Tuesday evening. It was great being able to share some experiences imaging the comet and seeing some familiar faces from 30 years ago when I was an active member!

Re: Comet Atlas showing nucleus fragment dissolving
You can definitely see a fragmented nucleus in one of the photos.? Very nicely done, Myron! ?

Hi David,
Thank you. Yes the one fragment just dissolves away. There is a cool HST image out there showing the comet fragmenting and dissolving.

Astronomical League Update
RAClub Members,
The Astronomical League Has finally been in touch. They have been having several internal issues that have been solved.
They are working on updating their website, so our information should be brought up to date soon.
The AL calendar year for the Reflector is July to June, so the time to renew is approaching. If you want to receive the Reflector please send the renewal fee ($7.50) to me by June 15. Several members have already paid, and no further action is required.
Thanks,
Matthew Scott RAClub Treasurer
