Grey Skies- Bright Moon Ahead

Last night I did observe a very bright moon and the planet Jupiter hanging in the sky after dark. Bad news for this week end Star Gazing Events. The forecast is for a full moon and more clouds with heavy rain on the way by week's end.

Bad News as the Cameras and Instruments went dark on the MESSENGER as the space craft skimmed 142 miles above the planet Mercury yesterday. The entire system went into safe mode as it received a gravity assist with this fly-by... NO DATA was collected. The Mission Team had to wait nearly an hour before contact was resumed.

Closer to Earth, the LRO zoomed past the Apollo 11 landing site on the moon again. This time in an orbit only 31 miles above the surface.

If it is Clear Tonight: Look south for Fomalhaut, the lone Autumn Star in the night sky.

Finding the LCROSS Impact Crater

News in Cyberspace this morning was full of New Impact information! First, I am hoping the LCROSS Mission folks will make up their minds as to which Crater they will aim at. Second, I hope the rocket hits the Target! Cabeus A or Cabeus proper?
NASA's Lunar Crater Observation and Sensing Satellite mission (LCROSS) based on new analysis of available lunar data, has shifted the target crater from Cabeus A to Cabeus (proper), according to a NASA Ames press release.The impact target decision was prompted by the current best understanding of hydrogen concentrations in the Cabeus region, including cross-correlation between the latest LRO results and LP data sets and after consultation with scientific community, including impact experts, ground and space based observers, and observations from Lunar Reconnaissance Orbiter (LRO), Lunar Prospector (LP), Chandrayaan-1 and JAXA's Kaguya spacecraft.Simualtion models show a small valley in an otherwise tall Cabeus perimeter ridge, which will allow for sunlight to illuminate the ejecta cloud on Oct. 9, and much sooner than previously estimated for Cabeus. While the ejecta does have to fly to higher elevations to be observed by Earth assets, a shadow cast by a large hill along the Cabeus ridge, provides an excellent, high-contrast, back drop for ejecta and vapor measurements.

The Crater lies to the west of the crater Malapert, and to the south-southwest of Newton in the South Rim of the Moon and may not be easy to pick up in the scope. This photo shows the Impact Area.

Whether we actually will see ejecta after impact remains to be seen. I will have the scope trained on the South rim in the area of Cabeus. We will need clear skies the morning of October 9!

Forecast: Mostly Cloudy

The Moon is bright going to full; playing hide and seek through the clouds. Another front is due in tomorrow. Hopefully cooler temps will follow and if it is strong enough, it will blow the clouds south!

Looking forward to the more close up shots of Mercury as MESSENGER'S long journey nears another Fly-by to this planet, closest to the Sun. MESSENGER is approximately two days from its third encounter with Mercury. If you look at our "Where Is MESSENGER?" page, which displays the spacecraft's trajectory status, you'll see that it is practically on Mercury's doorstep. This will be the team’s last opportunity to practice at Mercury before orbit insertion, so many of the instrument command sequences have been assembled to be similar to how they will operate during the orbital phase of the mission, which begins in March 2011.

There is Water on the Moon?

In several reports out today, a group of scientists have confirmed that there is water on the Moon! In ever so small amounts(one quart per ton of soil). Current evidence indicates that water content is higher at greater depths. Research from two orbiting Moon Missions have positive results. These combined with the Cassini pass report: Yes, there is Water on the Moon.

Other news from Cyberspace: MESSENGER will fly-by Mercury a final time and The new ALMA Telescope dish take a ride on the High Road. NASA has set the launch for the Ares I Rocket Test to October 27.

If the Clouds break tonight: Star Hop to the Andromeda Galaxy and look for bright Venus early in the morning, six degrees to the lower left of the star Regulus.

Monthly Group Meeting

Last night eight persons interseted in Astronomy sat at a table and discussed earthly things but not so much events in the sky. Topics ranged from where/when we will continue to meet to Star Parties and will we have enough scopes for Public Events. Not a large turnout but important issues were covered. When we left the building the sky was broken with Clouds. Jupiter was visible before a cloud covered him. Arcturus with the handle of the dipper was visible in the NW, the Scorpian and the Tea Pot were visible in broken clouds.

Satellites bring Alternate Season

Each year when summer is ending and there is a hint of fall in the night air, Satellite signals are turned to earth and the air is filled with sporting events beamed from Football Arenas to our TVs. Professional and College Football Season starts today. Tonight the stadiums will fill the night sky with lights in certain metro areas, making it harder to view a dark sky. College and Pro Teams will face off in open or domed arenas to fight for the honor of the WIN. Years ago, we would get maybe one or two games on the black and white TV on the weekend. Now, with the use of Satellites, the games we watch on TV seem endless, on Jumbo flat screens and in High Definition. The advancements in technology I have witnessed in my lifetime are truly amazing. Satellites are just one of many in the past two decades!

Weekend Event Horizon: Waning Moon, Cloudy Skies

The Good News is that Clouds and Rain are still covering Texas Skies in our area. The Bad News is that we still cannot view a clear night sky. Moonlight is no longer a problem but clouds rule!
Larry cancelled the Group SP at the YBJS Park Saturday night with no raincheck scheduled.

The cloudy weekend forecast will make it difficult to view stars over my sky, but Tammy covers several targets in the Weekend Skywatcher's Forecast: Mars, the waning Moon, Globular Cluster M56 and The Blinking Planetary Nebula.

Discovery Landed in California Friday evening. A You Tube Video places it on the ground at Edwards AFB. The Japanese H-2 Transfer Vehicle was launched and should arrive at the ISS Thursday.

Mark your calendar for October 9....More LCROSS Crater Impact information are covered in an Sky and Telescope article and noted in the news article from Universe Today.

Discovery Landing, LCROSS Crater Chosen

Finally, Rain showers here....and in Florida. The Rain at the Cape has delayed the landing of Discovery until this afternoon. First attempt is at the Cape is 2:47pm CDT. If showers hang around, the Shuttle will land at Edwards AFB in California Friday evening.


The LCROSS team announced Wednesday that Cabeus A will be the target crater for the LCROSS dual impacts scheduled for 7:30 a.m. EDT on Oct. 9, 2009.
They selected Crater Cabeus A based on a set of conditions that include proper debris plume illumination for visibility from Earth, a high concentration of hydrogen, and mature crater features such as a flat floor, gentle slopes and the absence of large boulders. "The selection of Cabeus A was a result of a vigorous debate within the lunar science community that included review of the latest data from Earth-based observatories and our fellow lunar missions Kaguya, Chandrayaan-1, and the Lunar Reconnaissance Orbiter," said Anthony Colaprete, LCROSS project scientist and principle investigator at NASA’s Ames Research Center in Moffett Field, Calif. "The team is looking forward to the impacts and the wealth of information this unique mission will produce."

Breaking News....Rain Showers, Hubble's New Photos

We missed the Shuttle/ISS double fly by last night, too many clouds. The area finally received some Rain this morning! High percent of Rain is forecast througout the coming weekend. This means the Larry's Event scheduled for Saturday will be a No-Go, for me!

No luck looking at stars but the Hubble finally started posting new pictures and they are Great!!! The orbiting Telescope released photos from all six science instruments. Shuttle Discovery is scheduled to land Thursday at 6:05 pm CDT.

Interesting article that covers types of Telescopes for Amatuer Astronomers was posted today from Universe Today.

Clear Sky before Dawn...some Cloudy Nights

Expecting more clouds in the evenings, it has been clear and cool in the early morning hours. Clear enough to view the Constellation Orion that has greeted me the past couple of mornings, as he rests abover the Treeline around 4:30AM. The Bright Dog star Sirius and Venus shine at Tree level. Mars is running higher in the Sky this month, not very bright, but red enough to see with naked eye. Also visible, the Gemini Twins with nearby Taurus and red Aldebaran drifting below the Seven Sisters looking down from the Top of the Sky. A hint of fall early in the morning; is it possible we may get a real Cold Front early this year?


The Shuttle Discovery will lock up today and undock from the ISS Tuesday. Friday, after Discovery lands, JAXA will launch a H-II Transfer Vehicle to the Outpost on September 11.

If the clouds break tonight: Look for Orion's belt to point to Sirius

Weekend Event Horizon...Cloudy

Forecast for the Weekend....Clouds and maybe some rain? There is still NO SUNSPOT ACTIVITY on the Sun! What affect is the sunspot cycle having on Global Warming? There is also a Full Moon filling the night sky with moon beams of light. Good luck spoting DSOs.

If you missed the Jupiter Moon Event (no Moons), our friend in Austin got some shots the night it happened. This is the time period of Saturn's Ring Plane Crossing. My dark Sky Blog covers the Event. LRO comes through again with another photo of the Apollo 12 landing site.

Tammy discusses several targets in her Weekend Skywatcher's Forecast. She points out the Full Corn Moon, A pair of stars Omicron 1 Cygni, items in Vulpecula and what to look for in the next few nights with Jupiter's Moons.

STS 128 is in Flight Day 8. Will complete third EVA Saturday evening. NASA announced today an additional Module will be added on the last flight to the ISS using a modified MPLM, "Raffaello".

Orion before dawn

Good chance of showers tonight/tomorrow and into the Labor Day weekend. Early this morning I viewed Orion laying over the tree line. Spica and Venus were bright and just at the tree line. I missed the ISS fly by at 6:33 AM. I will get more chances in the next couple of days. I was watching Shuttle Flight Day 5 Highlights, in HD, when I realized the Ship would be sailing over head! The 13 member crew will complete a Second EVA today.

Star Fields, Darker Skies

Took a recon trip to Pedernales Falls State Park, near Johnson City yesterday. Several Amateur Astronomers have mentioned the area to set up and observe the sky from this dark sky site. The site itself is a flat grassy area, close to the Bird Blind and the Horse Corral. Will have to confirm an overnight Camp out, because the park closes at 10. Had lunch in Johnson City and toured the Hill Country, came back through Kyle.

Last night Jupiter was left of the Moon. It is a waxing moon near Jupiter.

C--------(J)---I--------E---G

Tonight Jupiter will appear alone, NO MOONS. Look between 11:30 and 1:25 AM Thursday. This will not happen again until November 2019.

As we move to a Full Moon on Friday, keep watch for the star U Scorpii to super nova! Predicted to blow sometime this year.
