ASC 2016: Day 5

Day 5 of the American Solar Challenge marks the start of Stage 3, the longest stage. Beginning at Wilson’s Creek National Battlefield near Republic, MO, the solar cars pass through checkpoints at the Brown v. Board of Education National Historic Site (Topeka, KS) and Homestead National Monument, camping along the road en route to Scotts Bluff National Monument:

The day seems to have begun with rain again. Here is Principia’s morning charge:

However, skies cleared by the start:

The chart below (click to zoom) shows the standings as of this morning (i.e. for the first two stages of the race). The horizontal axis shows the distance (in km) from the start. The vertical axis is the time (in hours) that cars are lagging behind a theoretical baseline car that drove 75 km/h all the way. Higher is therefore later, and steeper lines are slower. Data is taken from the official timings. The vertical segment at the end of some lines represents the combined Stage 1 and 2 penalty time (this includes a small daily width penalty for Michigan, and larger penalties for some other teams). Teams with large trailering penalties (6, 17, and 55) are not shown.

Steep line segments on this chart mark the Day 1 problems experienced by Toronto (77), the general effect of the rain on Day 3, and the specific problems that hit Minnesota (35) that day. Michigan (2) are several hours ahead of everyone else, while Toronto (77), Dunwoody/SER (51), and Principia (32) are very, very close in 2nd, 3rd, and 4th.

In early racing today (see map above – click to zoom), Principia (32) is fighting hard for 2nd place.

Update 1: Michigan (2) reached Topeka, KS at 14:30:31, followed by Toronto (77) at 15:20:26, Dunwoody/SER (51) at 15:25:54, Missouri S&T (42) at 15:41:25, Principia (32) at 15:55:32, App State (828) at 16:00:51, and Berkeley/CalSol (6) at 16:07:35. Illinois State (17) were 8th, Minnesota (35) 9th, Iowa State (9) 10th, Poly Montreal (55) 11th, and ETS Quebec 12th – almost 3 hours behind Michigan. It is very good to see all 12 cars running well today. Here is the Toronto car in Topeka:

Here are the night-time positions of the cars at various motels and campsites. App State (828) are in Holton, KS, for example. These positions may therefore not accurately reflect positions in the race. And Michigan are well ahead of the GPS position on the map, having stopped at Beatrice High School, only 7 miles from Homestead National Monument.

Here are Michigan, in fact, doing their evening charging:

Update 2: Here is a revised race chart incorporating the unofficial timings into Topeka, and penalties for Stages 1 & 2 only:
