Subject: Hello


Dear Masatsugu,


Just a note to tell you that I have sent you another collection of Mars drawings today (from August 16 to 31). Even though the CMO has stopped for the time being, I have decided to stick to the old routine of sending you drawings twice a month, just after the 15th and after the end of the month. Hopefully you also received something from me concerning the last half of July and the first half of August, although I don't know if your mail continues to be forwarded to you (I send the stuff to Mikuni). I am quite aware how busy you must be!


There is one question I would like to ask you. I (and probably other dedicated CMO readers too!) shall soon run out of important Mars data, as the listing stopped at September 10 in CMO no.269. Personally, I am particularly interested in three things: data concerning the diameter of Mars for each day, the Ls for each day, and the declination of Mars for each day. - I have the Handbook of the BAA, which gives the CM for every day, but all the other data are only given there as one value every 10 days, which is unsatisfactory. If someone in the OAA has already made the calculations, do you think it would be possible to have the data laid out for us on the CMO homepage, while we're all waiting for the CMO to appear again???


I sincerely hope you're still enjoying Mars. I am, although now I'm really beginning to feel that it hangs low in the Danish sky. I had imagined that its low altitude here would show up in the form of bad seeing, but that has not been the case. The disk is big and bright, and I have often enjoyed quite satisfactory seeing so far - giving me a nice steady image. But somehow, the really fine details disappeared for me when its altitude changed from 19 above the horizon (which was okay) to 18 1/2 (which was not okay). So the main effect seems to have to do with the resolution one can achieve, not the

quality of seeing as such. Strange!!


Best regards to you and your OAA colleagues -

Dear Masatsugu,


Thank you so much for your fast reply. Oh, I don't think you're lazy at all - from the little I know of and about you I think you're an incredibly energetic person! And I just wondered about the mail, I didn't really expect you to acknowledge each and every collection of drawings that you receive. Although it does feel good to know that they reached their destination, I admit that. E-mail is a nice invention in this respect.


I'm glad you enjoyed such great conditions at Naha. You're right about the hot Europe this summer; even in Denmark, for exactly one month - July 13th to August 13th - we had incredibly stable weather, every day sunshine from a clear sky, calm, and from 25 to 32 degrees Celsius. But on August 13th it changed abruptly, and the weather has been unstable ever since. Particularly the clear nights now get very cold for the season (last night it was just 8 degrees Celsius when I observed Mars around 1:00 local time), as we're getting our winds from the Arctic right now.


I'm glad you called my attention to the ephemeris on the CMO homepage. I should have found it myself! Anyway, now I know it's there and shall certainly use it. Thanks.


I can easily see the dust in Mars' southern hemisphere. These last few nights the preceding (evening) S limb has looked very yellow to me in I.L., and what is more, this same region have been quite bright in W 25.


I have to leave now, to bring Mira to her swimming lesson. But thanks again, best wishes and clear skies to you -
