My anticipated “weekend” away from work is being extended by a planned 3 week vacation.

We are currently camped at a KOA in La Junta, Colorado. Yesterday, we camped at Sandy Cove Corps of Engineers campground on Canton Lake in Oklahoma.

Tomorrow we will be traveling on for a week in the Rocky Mountain National Park area. We’ll be camped in the park for four days. When we reserved our campsite for the park, there was nothing available for the Labor Day weekend, so we made reservations at the Estes Park KOA. We prefer to have spots reserved for holiday weekends rather than trying to find a campsite when there will likely be a lot of other people camping.

After Labor Day, though, we shouldn’t have any trouble finding a place to camp.

We will be traveling on Labor Day, though…, and will probably be traveling I40, which brings back memories of another Labor Day on I40.

In 2001, we were headed from Steamboat Springs to Estes Park and decided to go by way of Golden to see a quilt exhibit. We didn’t even think about the fact that there would be heavy, heavy traffic heading from the mountains back to the cities.

We ended up in a traffic jam backed up for miles.

Fortunately, this time, we’ll be heading away from the cities, going west.

Here are a few photos from yesterday at Canton Lake:

The following “drawing” of boys at play in Lake Canton was rendered from a photograph using Corel Paintshop Pro Photo X2.

While I will be “off-line” and away fro the internet until Friday, there will continue to be daily posts that have been “pre-published.”

I plan to have more photos to share later in the week.

This post is being simultaneously published on Exit78 and Haw Creek Out ‘n About.

The Sun has Lost it’s Spots (continued)

Today, it reached a count of 700 days.

On average, a solar minimum has 485 days where the surface of the sun is blank, with no sunspots appearing.  The solar minimum is the period in a sunspot cycle where the number of observed sunspots  is at its lowest. Sunspot cycles  average 11 years from beginning of minimum through maximum and back to the beginning of the next minimum.

The current solar minimum began in 2004 and was predicted to end late in 2007.

Since the minimum began, there have been 700 days with no sunspots.

The last observed sunspot disappeared 47 days ago.  If there are no sunspots by this time next week, this will have been the longest period without any sunspots during this minimum.

Long solar minimums have been observed in the past. However, this is the first long minimum where we have had sensitive instruments that can monitor the sun.

The jury is still out on the meaning of this extended minimum.

Advocates of the hypothesis of anthropogenic global warming discount any significant change in the energy received from the sun.  Others, however, point to previous periods of low sunspot and solar activity, which, by chance, happened to roughly correspond to the cold times of the Little Ice Age and the Dark Ages.

(to be continued in about a month or so)

Note: Previous posts on the sun were The Sun Has Lost Its Spots (Part 1, Part 2, and Part 3) and The Sun Has Found Some Spots. I will be posting a continuation update about monthly.)

The Photochrom Print Collection has almost 6,000 views of Europe and the Middle East and 500 views of North America. The richly colored images look like photographs but are actually ink-based photolithographs, usually 6.5 x 9 inches.

I’ve been working quite a number of hours in the simulator the last few weeks.

One of the requirements for reactor operators is that they demonstrate the ability to start up the reactor.  Each candidate practiced the reactor startup 5 times and then had a startup where he or she is evaluated by someone from Operations management.

So that’s a total of 6 startups for each student.  There are 12 students, so, over the last few weeks, there have been 72 startups for training or evaluation — and I was there for every one of them. Total time in the simulator for this was about 84 hours over a 4 week period — about 20 hours a week. And that doesn’t include the several startups that I did to verify the scenario I was using and to establish the conditions for the evaluations.

This week, I am working in the simulator from about 4 PM to midnight every day, providing support and guidance for a crew of students who are shutting the plant down and cooling to “cold iron.”  Once that’s done, they’ll be doing a heatup to normal operating condition, with a startup and power escalation to as high in power as we can get before the end of the shift on Friday.

I’ll certainly be ready for a rest when the weekend rolls around.
