On that site, the default map doesn't show much detail so I'll outline a few settings I've found helpful if your computer or other viewing device displays and can handle them. When you're using the SBARC Earthspot site and listening to their K6TZ Repeater, you'll hear occasionally hear mention of what it's displaying. I find it useful to keep them both open in different browser windows.
•At the top-right of the map portion of the site is a rectangular box labeled "Contrast" that you can pull-down that menu and select Terrain (2nd from the bottom) to get great detail you can zoom in on and compare with other stuff you find that's using gMaps Terrain mode.
•At the top-left of this same map screen is a box with a gear icon named "Menu" that you can click. The third option from the bottom of the menu that pops down is "Shortcuts" where you can click "Pause" to minimize your data use while retaining your settings.
•If you click the Menu then "Options" and then "Filters" you can disable all the airliners high above that are irrelevant to the fire. Because the FAA has issued a massive Temporary Flight Restriction (TFR) over SB & Ventura County areas in the fire area, only fire aircraft can fly below the 9,500' TFR. So next click "Filters" then the Enable checkbox, then pull down the box labeled Airports. Pull that down and select the next item down named "Altitude" and click the "+Add Filter" box. "Between" appears and to the right of it, type in the number 1 to set the lowest altitude at which an aircraft will be displayed. In the next box to the right, type in 13000 and pretty much only fire aircraft and the occasional news helicopter will show up over the fire area. Instead of 13000 you can of course type in 9500 to stop displaying the news flights. If you don't have an easy way to input those numbers you can use the up arrows next to the boxes to input the numbers you want. Note that right now there's a fire survey aircraft up above 16,000' if you'd like to watch it.
•Other settings I like are:
*Menu/Shortucts/Disable Auto Select.
*In the Menu/Options/Aircraft items:
+Number of label lines: 2
+Aircraft label line 2: Altitude
+Show Short Tails
