18 July 2010

I was supposed to have backed out some past observing reports this weekend. Unfortunately my laptop died during the week and we think it is beyond resuscitation. It was an old machine. I have a new, to me anyway, MacBook on order but it may not arrive until the end of the month. Then it is going to take a while to set it up. Some of my astronomy software is PC only so I am going to have to run a virtual machine and install Windows and the PC programs on it. I had been doing nightly backups of most of my data so I probably haven't lost much. But the back out I had started last weekend was saved to the desktop and that doesn't get backed up. And each time I entered the data into the blog template I deleted it from the Palm log so half of that nights Observations may have been lost forever.

The weather tonight was a lot worse than NOAA or any of my other weather resources had predicted. Peter had brought the TelePort but never bothered to set it up. We did a little naked-eye observing but mainly talked since it has been a couple of weeks since we have seen each other..

Later in the evening when Venus dropped into more atmosphere it lit up a ring of haze around it. This effect is very prohounced in the binocular but visible to the naked eye.

CommentsVenus was the first planet to become visible which was nor surprising since it is the brightest planet.  I was surprised at how easily I found it and recovered it naked eye before seeing it in the binocular.  Once the sky got dark it looked planetary even to the naked eye.  The binocular view doesn't give any hint of phase.

CommentsMars was the next planet to become visible which was surprising since it was not as bright as Saturn. Which was in a part of the sky where the contrast was a little better.  I estimated the offset from Venus based on the information in Planetarium and there, after a while, was a faint reddish dot which became planetary in the binocular.  Tracking back along the ecliptic with the binocular I located Regulus which did not become visible to the naked eye until 2101 EDT.

CommentsSaturn was the last of the planets to become visible.  I don't think I ever looked at it in the binocular.

Extending the line from Venus to Saturn it was my impression that Regulus and Mars were both slightly below the line.

30 June 2010

This month has not been a good astronomy month.

Sunspots Observed

My only solar observing this month was the Sun Triangle alignment on the June Solstice.

CommentsI arrived early for the Sun alignment to take some measurements.  I has already checked my SoHo app and knew that there is a sunspot group in the NW quadrant of the Sun which is supposed to be growing rapidly but is probably still too small for me to see with my 8x hand held binocular but I gave it a try anyway.  I didn't see anything through just the welders glass so gave it a try with the glass Helsinki in front of the binocular.  I wasn't able to get ten sun into sharp focus.  I suspect that there are two many air/glass boundary transitions for this system to work well.

R = (Groups * 10) + Spots)

The Sun Triangle points to approximately 240° magnetic.  I tried laying my iPad and compass along the edge of the pedestal but, as I suspected there would be, there appears to be a ferrous framework within the Triangle that is sheathed in a shiny metallic skin and I can't get compass readings there.

Planetarium says the Sun will be at azimuth 180° magnetic at 1241 EDT.  At 1242 EDT I measured it's azimuth to be about 186° magnetic.

The alignment appeared to have occurred at about 1257 EDT but I can't be sure of that because one of the local Druids had to stand under the point of the Triangle where he was casting a shadow where the shadow of the Triangle's point should have been.  And he was not looking either up the edge of the Triangle or back at it's shadow.
