Dear Masatsugu,


My cousin Noel Cumbia mentioned that a friend of his, Dick Schwinn, has been imaging Mars with his webcam. I suggested that he send his images to you, and I understand that he did so. I hope his imaging proves useful to your CMO.


The weather here continues to be poor for observing, especially when I am not working.


Tyler was sick last night, and I stayed up with him. I have to try to sleep fast in order to work this evening. With luck, Tyler will be well and the sky will be clear when I get off around midnight.

Dear Masatsugu,


Attached you will find a sketch made this morning. I was pleased to note some details in the shrinking south polar cap. I hope you will forgive me if I look up the CM, etc. in the morning after a good night's sleep.


I will try to write to Dick Schwinn in the morning, regarding the data you need.


Tyler was released from the hospital this evening. He is doing well.

Here is what I wrote to Dick Schwinn this morning. I hope it was what you had in mind.

Masatsugu Minami wrote yesterday and said that he needs the appropriate data for your Mars photo: date, time, instrument used, magnification, seeing, transparency, observer's name, and observing station. It would also be helpful to include the central meridian longitude, De, and Ls. These last three can be determined using tables found on the pages of ALPO and OAA. If you need any help with any of this, let me know. Maybe one day you can tell me how to do some good webcam images of Mars. I had a good view with my 6" Newtonian last night, sketching Solis Lacus and the diminishing south polar cap.


I mis-spoke yesterday when writing that he prefers celestial west on the right. He likes it on the left. That is the traditional orientation in the days before Schmidt-Cassegrains. Maybe you have a program that can mirror reverse your image. If not, Masatsugu, will probably be glad to get it anyway.


I should not write emails after staying up all night.


Best wishes,

Thank you for sending the very fine Mars image. Dr. Minami will surely appreciate it. I will drop him a word of introduction. I think he likes having his Mars images oriented south at the top and preceding (celestial west) at the right. Anyway, that's the custom.


I was up most of the night with my sick son, so I will try to grab a couple of hours of sleep, will write more later.


Noel's cousin, Sam

I am the fellow that Noel told you about that has been doing some astrophotography. I started with an Orange Tube C-8 back in the mid 80s, but didn't really do much in the 90s. About 6 months ago I decided to give digital astrophotography a try and I am now hooked again. I sent the picture I've attached here to the CMO - I wasn't sure how to submit it so I just sent it to the guy who is in charge of the photo page. It isn't perfect, but it is the best I've done so far. This one was taken with a TAK FS102, 4X Powermate and a Phillips Toucam.

Sam Whitby suggested I send any Mars pictures I have as you may have some interest in them. The weather has been bad here all summer, but on the 17th I was able to get some descent pictures. The one I am enclosing was taken with a TAK FS102 with a 4 X Powermate and Phillips Toucam. The images were stacked and then processed with "Images Plus." I hope you find some benefit with this picture.

The attached is a scanned image of a Mars sketch that I made this morning. The planet's image was still but very dim due the August-in-Virginia haze. The edge of the spc looked ragged, but I could not make out any specific details. Solis Lacus and its environs were dusky on the preceding limb. I could not detect a north polar hood.
