There was a mutual event of the Galilean satellites on this chilly Wednesday morning. From09:12 to 09:16 UT Ganymede partially occulted Io. Io was reduced to15% of its normal brightness.I watched as Ganymede and Io drew close, seemingly merged, and thenwent their separate ways through my Orion ShortTube 80 achromat at 57and 114x using a 7mm Tele Vue Nagler type 6 alone and with a 2xCelestron Ultima Barlow lens.I also briefly viewed the just past opposition Saturn and the nearlyfull moon at 114x.For more on this mutual events "season" see the article by Jean Meeus in the December "Sky & Telescope" and on the Sky & Telescope web site (http://skyandtelescope.com/printable/observing/objects/planets/article_774.asp). There is a similar article by Richard Talcott in the December issue of "Astronomy".

Well, with a bright moon in the sky, Jupiter sounded like as good as any target. I was surprised to see a moon in transit accross the planet. I never noticed one before, so it was a pleasant surpise. Early in the evening while Jupiter was still low in the sky, I noticed 3 of the prominent moons just to the west of Jupiter. Later in the evening, one was missing. At 59x, it wasn't really detectable, but increasing magnification to 157x, the small black dot just north of the southern belt was clearly seen. From my perspective, as the evening wore on, it was transiting from right to left accross the planet as the evening wore on. Quite a fun find.......

This evening I observed Jupiter at 133x. The great red spot is now beginning to take on a pinkish shade to it. It still has a tiny black dot in the center of the red spot. I also noticed the north equitorial belt is now much more pronounced than the south equitorial belt is. Last week both belts seemed about equal. I also observed Saturn at 200x. Saturn now has a white spot on it that several observers, including my friend Joe Cseh has seen. So far, I have not seen this white spot but I will keep looking for it. The one thing I do notice about Saturn is its south polar hood is much darker this year than I have ever seen it in all the years I have observed Saturn.

This morning,I was able to observe the great red spot of Jupiter. The spot had only an ashy grey color to it. I also noticed a tiny black dot in the middle of it. I also was able to observe the shadow of either Io or Europa just to the left of the great red spot as seen in a newtonian reflecter. Once again, the north equitorial belt was loaded with festoons, but unlike last year it looks smaller than the south equitorial belt.

This morning, at 133X, I noticed that the south equitorial belt was wider than the north equitorial belt. However, the NEB had a number of festoons on it. It looked very lumpy. The north temperate belt showed quite well this morning. Finally, the south polar hood was much brighter than the north polar hood.

Even though Jupiter was low on the horizen, I still was able to observe it fairly well at 133x. The north equitorial belt had some festooning on it, while the south equitorial belt seemed very smooth. The north temperate belt, which was easily seen last year, was seen with great difficulty this morning. The south polar hood was evenly shaded, while the north polar hood was only very slightly shaded.

At a local star party, we used a 12.5" dob. toview the 5 naked eye planets gathered in the western sky. Jupiter was spectacular. The north eqitorial belt had several large festoons on it.We also noticed how the north temperate belt had also become obvious.The red spot was not on the earth facing side while we viewed Jupiter.We also viewed Mercury and saw some albedo darkening on the limb of Mercury, just below the equator. Venus was almost at full phase. On it we saw some darker shadings on its cloudy surfce.Saturn's south polar hood showed wellBut we were not able to see the cassini division on its ring systom.Mars had a orangy tint to it and it was in a gibbous phase.

Jupiters north equitorial belt was bright and maroon colored at 200x. The south equitorial belt was about 70% as thick as the neb but showed. The north teperate belt was a long pencil line. The south polar region was much darker than the north polar region. The great red spot was not out this evening, but at other times I've seen it as an tannish colored object. Michael Amato

Tonights sky was good, with slight turbulence in short intervals. I first turned my attention to jupiter. I put in my 25mm, which yielded a magnifacation of 36x. I could easly distinguish two large cloud bands bands near the equator of the planet, they both looked pale brown in color. I also could see 3 satellites. 2 on the western side, and 1 on the eastern side. Then I put in the 12.5mm, basically the same image. The planet was quite more turbulent though. Just for experementation I put a lunar filter over the 12.5mm, and wow! It gave me much more contrast, yielding alot more definition to the planet. Next I turned my attention to saturn. Using the 25mm the ring structure was easily destinguishable. I switched to the 12.5mm. Half way up up from the equator. I thought I was seeing a cloud structure, or bands. But was not sure, so I decided to put in the 5mm, yeilding a magnifacation of 186x. And sure enough I could see a faint cloud band near the top of the planet. clear skys!!!

I went to a small park on the east side of the St Johns River and was treated to a beautiful view of the conjunction of Jupiter with Mars and the Moon with Saturn.I used a low-light video camera (Supercircuits PC23C) with 50mm Contax f/1.7 SLR lens (giving approximiately 5 degree FOV) to record real-time images to Hi-8 video tape. I digitized the recording using Dazzle video capture device and made a mosaic of three still images.The mosaic and the full video are available on my FTP site at ftp://24.129.70.60 A high speed digital or cable modem is recommended for the video, since it runs about 35 Mb.

I hadn't been out observing in many months, but my first view through the eyepiece on this clear, cold evening definitely rewarded me: Jupiter, with two of the Galilean moons perched just off the disk like Mickey Mouse ears, and the Great Red Spot (I assume; a dramatic dimming of the SEB, at least) approaching meridian transit. A few hours later, after dinner, I looked again, and now Mickey's ears were both next to each other, and the SEB was a solid band. Some fairly dramatic detail was visible in the NEB during this later observation.

While observing Jupiter on Saturday morning I noted three small red spots (barges?) in the NEB. The most prominent red spot transited the CM around 05:20 UT. There were two others, one preceding this spot and one following it. The red color was verified by another ASH member. Observations were made at 202, 249, 259, and 324x using the 17" f/15 classical Cassegrain located at the ASH Naylor Observatory. The festoons themselves were unmistakable and had a somewhat bluish tint. Early Friday night the seeing was rather poor and I used a 10" aperture mask. Later on the seeing became quite steady but it was rather variable.This was the second night that I noted these red spots during this year's Jovian apparition.

Tonight, I was able to resolve Jupiters 5th closest moon, (which I have researched and discovered to be 112,500 miles from Jupiter's surface). It was detectable, although its albedo was much lower than the four major moons. It was positioned the alloted distance from Jupiter. I caught this moon with 144X and had a clear view of same. This was my first ever sighting of any moon other than the "Big Four." Anyone know the name of this moon?

Tonight, observed Jupiter for the first time since last fall. It was extremely bright and was easy to spot naked eye. All 4 giant moons were plainly visible as were the northern and southern equatorial bands. We had extremely low humidity here (around 20%) and the seeing was quite good. Jupiters disk seemed somewhat brighter than this time last year. It is coming to opposition soon.

Recently returned to astronomy after a long layoff so started with the obvious observation targets. Jupiter, low to the horizon, was hampered by only fair seeing (and tube currents in my scope) but even so had moments of wonderful cloud detail even without a filter at 100x. Main impact of tube currents was some ghosting. Venus was too bright without a filter to look like much of anything. Saturn, higher in the sky, was the best of the three. By the time I targeted it, my tube currents had settled and the seeing was slightly better. Good cloud detail and a surprising number of moons (4-5 I think). Actually jacked up the power to 240x (just below by theoretical max) and still had good detail.

The Sunday night forecast was for rain but the skies stayed clear long enough for me to witness the reappearance of Io from eclipse. I used my 114mm f/7.9 C4.5 at 106x (17mm Tele Vue Ploessl with a 2x Celestron Ultima Barlow lens) and 134x (6.7mm Meade UWA) from my residence about 10 kilometers east of Harrisburg, PA. Prior to the event Ganymede was situated to the west of the planet and Europa and Callisto were to the east, fairly close and quite distant respectively. Because of increasing haze it was somewhatdifficult to see Io come out of Jupiter's shadow at 23:41 UT. By 00:30 UT (1/18/99) Io was directly north of Europa. As Io continued eastward (away from Jupiter) and Europa westward (to begin a transit of Jupiter at 01:51 UT) they assumed a more horizontal configuration as Jupiter disappeared into the western tree line.

Tonight I viewed an interesting dance of three of the Galilean satellites as a shadow transit of Europa transpired (22:54 to 01:31 UT). When I began observing at 00:20 UT Europa was well clear of the western limb of Jupiter and formed a right triangle with Ganymede and Callisto. By 01:36 UT the right triangle had transformed into one of the isosceles variety. As Ganymede continued its eastward progress towards occultation at 04:56 UT the isosceles triangle changed aspect and narrowed (00:50 to 01:00 UT). By 01:35 UT the three moons had formed a dogleg pattern. As time passed the dogleg straightened out somewhat. Jupiter was well into the western treeline at 02:30 UT, the time of my last observation. I used magnifications of 106 and 134x under rather unsteady seeing conditions.

I witnessed one of the moons of Jupiter reappear from eclipse this evening. Prior to when Io emerged from Jupiter's shadow the only Galilean satellite visible was Callisto to the west of Jupiter. Europa and Ganymede were transiting so a casual observer would notice that Jupiter had but one moon! One minute later at 23:13 UT Europa's transit ended. At 01:54 UT Ganymede cleared Jupiter's disk. Shortly thereafter all 4 satellites were visible once again.

Tonight, after enjoying a great Thanksgiving dinner, we looked toward the setting planet, Jupiter. We have seen this gas giant several times through binos and my telescope. What made tonight's observation different was the location of Jupiter's moons. Io and Europa seemed so tidally locked that they appeared as "binary" moons. They were so close to one another it looked like they would crash!. Equatorial bands on Jupiter were very evident. My small scope would not resolve the "Great Red Spot", however it's moons were awesome. Clear Skies, everyone!!

Jupiter was spectacular this evening. I observed what I believe to be the moon Io transit the planet. (if I am reading my S&T chart correctly) the moon was a very visible black dot and at times I could see the shadow cast on the planets surface. Allot of detail was visible on the surface. several cloud bands were very apparent. I also observed Saturn for a time but it was low on the horizon and very turbulent viewing at high power.

I had a good session of observing Jupiter this evening. A thin veil of clouds helped to keep the brightness down which actually helped I think. I could see alot of detail on the planet at high power. I think I saw the giant storm But I'm not sure. Only 3 moons were visible for an hour then the 4th peaked out from behind!

Tonight I had a good observation session of Jupiter. The planet rose about midnight but no good views happened until 1am. with my 9mm eyepiece I could see 4-5 cloud bands and 3 moons were visible while I observed. It was still pretty low on the horizon so the air was turbulent but clear views presented themselves with continuous observing. I was unable to stay awake until saturn rose. maybe next time.
