It had been cloudy earlier and looked like impending rain but is clearing off as I am observing. The wind is strong and gusting. Dust is being blown up from the streets and is getting in my eyes.

It looks like the times listed in Space.com are wrong again today. I observed the Sun to be lined up with the center of 34 St and above the mountains on the NJ horizon at 2010 EDT. When I got back into the street on the next light change the Sun had moved to the northern side of the street and was 1/3 down. There is no way that the Sun would be lined up with the street grid at 2017 EDT.

It was the usual observer pandemonium as people ran into the street to watch and photograph the Sun on each red light for the crosstown traffic. But added to the confusion this year was a backup of traffic heading east. I suspect that President Obama was still in town causing the delays.




Sunspots Observed

I was not able to do any solar observing this month. TheSun has been a little more active this month than last but there probably wasn't anything there that I would be able to pick out with binoculars anyway.

It had been cloudy out to the west earlier in the day but seems to be clearing up now.

Space.com said the event would take place at 2017 EDT and at that time the sun would be ½ below the horizon. I found that the sun was lined up with the center divider line of the street at 2010 EDT and the entire sun was above the horizon which is a hill on the NJ side of the Hudson River so well above where the real horizon would be if I were looking out over the ocean.

President Obama was having dinner in the West Village when I arrived in Washington Square Park to read before the Henge event. I figured that since he was going to the theater tonight he would be leaving the Village around 1930 EDT so went up to 14 St about then. I saw the motorcade pass by and the presidential lomouisine (I thought it was supposed to be a two-tone venicle) but can't say that I saw him waving as others saw.

I may have estimated the asimuth incorrectly. I don't think there was enough cloud up there to have obscured a mag -2. I was able to see Spica (Mag. 0.98) lower down on the horizon.

I read an editorial on the last page of the June issue of Sky and Telescope where the big advantage to Moon exploration and colonization is that it take 1/22 as much fuel to launch from deep space from the Moon as it does to launch from Earth. But we are Earth-centric and everything that goes anywhere comes from and is controlled by here. Mission control practically has to tell astronauts it is OK to breathe. So where does the fuel savings in launches from the Moon come from if we first have to launch components from Earth to the Moon?

Sientists think NYC was hit by a giant tsunami about 2,300 years ago. There is debate on whether the evidence is actually a tsunami and what caused it if it was. Some people think it was an underwater earthquake and others a meteorite or asteroid impact.

NASA has confirmed 1401 EDT on 11May09 as the target for the launch of the HST Servicing mission.

They have also announced that they are laying off as of today the first 160 of about 900 Shuttle workers to free up funds so they will be able to remain within budget through the end of next year when the Shuttle fleet will be retired. They said that everyone being laid off right now is contractor personnel who are engaged in Shuttle construction. I would assume that the contractors have some subcontractors working on the Shuttle program and that these contractors to the contractors will be gin to jump ship and move to the private space industry causing an even faster trim down of the Shuttle program staff.

Let There Be New Flowering

let there be new flowering
in the fields    let the fields
turn mellow for the men
let the men keep tender
through the time    let the time
be wrested from the war
let the war be won
let love be
at the end
