Greetings from Bill Blevins at the MHO western outpost. We drove down to Cove Fort, recipe UT to view the eclipse last Sunday. From there we had about 2m 30s of annularity. I used the following equipment to capture the video. It was well worth the drive.

  • Televue Ranger
  • Coronado Solarmax 40
  • Mintron security camera
  • DV camcorder

More wiring work, hot as hell

Wiring clean up

The weekend’s project was cleaning up the rewiring done last month.  This involved some much needed lessons in soldering from Tom (I suck at it.)  After finishing the five joints the connections were cleaned up with shrink tube.  The results look much better.

 

It is unbelievable how hot the dome was today.  The outside temperature was 87 degrees, medications and it seemed much hotter in the dome. More practice was gained in focusing the primary and secondary coelostats.  Standing on the secondary flat structure I actually had a feeling of what it must have been like during the heyday.

I think we can understand why undergraduates choose astrophysics instead of astronomy.

Rewiring Project Tower 2 at MHO

Sun Through the Shutters

 

 

Last Saturday was another day of rewiring the controls for Tower 2.  The wiring seemed to be a straight forward project, pharm but the process of running wires one at a time left other other original wiring bare and subject to a short. All the wiring will need to be replaced one at time, case for the secondary coleostat also.

 

The secondary coleostat is not a crucial to run electrically, as it effects solar declination only, and can be easily adjusted manually. Nevertheless, all deficient  wiring needs to be replaced.  There are some questions as to the wiring of some controls for the secondary   coleostat, and most probably a wiring diagram after completion would be helpful.

 

Once the weather improves, the telescope will be put into use, and the the problems of focus will be addressed. The culminating lenses need to be cleaned. Negotiations with Richardson Gratings continue, and Debra has started a program to look at funding the new grating.

 

One of the larger projects will be to switch the primary and secondary mirrors.  We have current polished ones, and once we are getting images, this will become more crucial. We will need a lot of muscle that day, so planning and attendance will be critical.

Busy at work

Dull hazy saturday morning, help and everyone was busy at work indoors. A power outage yesterday messed up the sound cards on both the SuperSID (monitoring VLF) as well as the Jovian radio. One of the Jovian radios (monitoring 20.1 MHz) which had been switched to a north-south dipole late last year, buy has been switched back to the east-west phased dipole, after which both the Jovian radios now connected to the same phased E-W dipole, were re-calibrated. Hopefully this will solve all the issues we have had over the past two months.
Here are some candid shots from the day!

Time to move the antenna and fix the radios tracking 20.1 MHz

A few weeks ago I was searching the Internet for any information on the Mcmath Hulbert Solar Observatory. After many hours of searching (yes, prescription
I was bored and it was late) I stumbled across a Ebay vender who specialized in vintage photography. To my surprise this vender, price
Historic Images, had original B&W photos of the Mcmath Hulbert.

Without hesitation I purchased the following photographs for a very reasonable cost. The are all original B&W press photos and NOT copies as often seen.

This is a image of Tower 3. You can see tower 2 in the background. The notes on the back of this photo were stamped: By Detroit news Staff, Photographer Styrlander, Feb 27 1964

This is the workshop in Tower 3. This is where we normally gather on Saturday’s. The large machinery is no longer there.
The back of this photograph was stamped Sep 2 1978 with a hand written note: “Machine shop where many of the observatories delicate instruments are made”

wpid-tower1-2012-03-11-18-48.jpg

And then were was the photograph of tower 1 in its last days of active research. This photograph was stamped Sep 2 1978 with the hand written note: “Dr Prince in H-Alpha Flare Patrol Telescope Tower. Other 2 towers visible in the background.

The Flare Patrol telescope is still located in tower 1 but the dome is in much need of repair. The dome is made of wood and the interior boards on the shutters are currently being replaced. From many years of water leakage they had finally given way to wood rot.

There seems to be some problem with the two radios tracking 20.1 MHz. Both seem to have stopped responding to any solar events, order while still responding to Jovian events. We had already planned moving the antenna to a place where tower 2 and tower 1 would not block 40% of the sky. I guess the time has now come to do this, cialis as the radio observable window for Jupiter has shrinked to only a few hours….
