Here is an unprocessed image I capture on the Corona Camera yesterday. It not only shows the Diamond Ring but also a flash spectrum! More about the expedition to follow.

One week from today and the Moon will eclipse the Sun! All the equipment is packed and ready to travel. The expedition leaves for base camp in 3 days. Everyone is very excited and ready to go. Last minute provisions are being acquired...we are going to be self contained as the center line locations should be pretty much maxed out.

Two of the eclipse crew checking out pin hole solar viewers...notice the technique of these two budding solar astronomers! Well there are 10 days until the eclipse...plenty of time to refine the technique. Pix by MM Iadevaia

Here are the first three slides of my eclipse talk I will be giving the night before the eclipse. It is estimated that 500 people will be at the camp ground for the eclipse! Maybe I should put out a hat. :-)

Tonight the pursuit of the Sun by the Moon has begun. On Monday, 7 August, the Moon will be full as it moves closer toward its new moon phase in 14 days...then on 21 August, the unseen Moon captures the Sun and for about 2.5 minutes subdues its light to extinction. The Great American Eclipse has begun!

IMPORTANT INFO REGARDING LIVE VIDEO STREAM FROM ECLIPSE BASE CAMP
Live streaming of the eclipse and activities pertaining to the eclipse will be sporadically transmitted between 8:00 AM to 2:00 PM MDT (1400 to 2000 UTC) on the day of the total solar eclipse, 21 August 2017. Streaming will include the actual period of totality which will begin at 11:20 AM MDT (1720 UTC)... totality is at 11:45 MDT (1745 UTC). If you miss the live stream the sessions will be recorded and available on my YouTube Live Channel. If you are at one of the grandkids’ school tune into the channel and leave your computer on the channel from 8:00 AM MDT (7:00 AM Tucson time) to 2:00 PM (1:00 PM Tucson time) and anytime we transmit a segment you will see it live.
Teachers of the grandkids…the grandkids will be transmitting their reports during this time period. Their parents can send you a text when they will actually be on air. Be sure to give their parents a number to text to if you need to know specific times. That’s the best I can do. I will be extremely busy up to totality collecting data and making sure the science equipment is working properly.
The URL for my YouTube live stream as well as the recorded sessions is:
The live video stream is dependent on a trouble free satellite uplink from my satellite ground station. There will be a delay of 0.75 seconds or longer due to the round trip of 48,000 miles from my base camp to the satellite and back and bandwidth usage at the time. You will not notice this delay except the times of the activities transmitted from the base camp time stamp might differ from your local clock. That is the reason I will start the totality coverage at 11:20 AM MDT.
If the weather is not cooperating at the base camp we will be activating the escape plan and head to clear skies. The eclipse will be recorded with portable equipment and uploaded to the satellite when we return to the base camp. That video will also be available on my channel.

Several people have ask me about taking a picture of the eclipse using a cellphone. There are several problems that arise. The first is if you do not have a proper solar filter covering the lens of the cellphone camera during the partial phase DO NOT try it.!!!There is a very good chance that you will fry your cellphone camera's detector. However during totality, when you remove your solar glasses, you can attempt to take an image of the eclipsed Sun. The second problem is one of focal length. Below you see two images of the Sun...one taken with a cellphone at maximum zoom the other image is taken with a 600 mm focal length lens...both with proper solar filters attached...guess which is which?? Go ahead an try you never know what you might capture! Some cellphones have great zooming capabilities. Try zooming in on the Moon this week to see how big an image your cellphone camera can display. 17 days until the eclipse!

All testing has been completed and the equipment is now in bins..a total of 10 bins! The satellite ground station will be the last piece of equipment to be packed up. Linda is coordinating base camp organization. Elise and Wyatt are planning special meals for the entire base camp group the day and night before the eclipse. The grand kids are getting excited. Everyone is pitching in to make this a very special event. Now the weather watch begins and the escape plan has been made but hopefully not have to be implemented...but the goal is to see the eclipse...the science in this case is secondary...because I will be with my children for a total solar eclipse...I have waited 26 years for this!
