LtE in CMO #246,247,248

From Frank J MELILLO


@. . . . . . Here are my latest images of Mars on 6-9-2001 UT. The seeing was terrible again. But at least, the images came out pretty decently. Regards,

@. . . . . . Here are my latest images of Mars on 6-20-2001.

 The seeing has been below average lately.  So all my images are so-so even though I was using the adaptive optics. Most of the time, Mars was  imaged when it was no higher than 23 degrees above the southern horizon. From what I remember in 1986 Mars' apparition, which is similar to this one, the seeing was a lot better. I guess in July and August of that year, we had a  long heat-wave (Bermuda high) here in New York and that may caused the air mass to be more stabilized.

  Let's see what happens next month or two and perhaps the seeing will be a lot better!

@ . . . . . . . . . . . .Just a short note as of July 3rd at 4:00 UT. The seeing was terrible due to the strong cold front that went through last night (Sunday night) in New York City area. According to my CCD images (not fully process yet) and visual report at 60 degrees CM longitude, M Erythraeum and Aurorae Sinus are seen well with perhaps lower contrast. Solis Lacus is difficult to see.  I'm not sure if this relates to dust clouds approaching that area that lowers the contrast or just a bad seeingcondtion.

 Also, again, I'm not sure if I suspect any dust clouds yet along the eastern limb.

  Let's see what happens later this week!

I will send my images shortly

@ . . . . . . . . . . . Here are my latest images of Mars on 7-3-2001. A strong cold front went through the night before so the seeing was 2 on the ALPO scale. I used the adaptive optics and I did my best to bring out as much details as possible.

 With Wr. #25, yes, Solis Lacus is visible with a weaker contrast and so is Tithonium Lacus just to the North. The images look very weird with all haze around the limb. The SPC may be seen but it was difficult to judge. At this CM longitudes at 59 and 66 degrees, it is hard to judge whether the dust clouds can be seen especially along the eastern limb.

More later........

@ . . . . . . . . . . . .Here are my latest images of Mars on 7-7-2001 4:00 UT. The seeing was 2 on the ALPO scale. Mars looks very unusual at 25 degrees CM longitude. Some features are hard to recognize. Most of the information is printed on this jpeg file.  Regards,

@. . . . . . . . Just a short note. I was imaging Mars last night (July 10th at 4:00 UT)and the seeing was a lot better first time in a month!! The CM was about 0 degrees.

In Wr. #25, yes, Merdiani Sinus is completely obscured by the dust. But Sabaeus Sinus is visible as a long thin streak. Mare Erythraem is the darkest feature on the disk but Aurorae Sinus is obscured by the dust also. To the north, very weak contrast where Niliacus Lacus and Mare Acidalium are located. The SPC looks smeared along the southern limb.

My images will follow shortly. Regards,

@. . . . . . . .Here are my latest images of Mars on 7-14-2001 at 4:14 UT.

   Syrtis Major is at least visible thought the dust and Mare Serpentis is the darkest area on the disk.

More later........
