Solar Eclipse Google Map Help. A click anywhere inside the penumbral area of the eclipse will display a tooltip with the local circumstances. At the same time the ant umbral shadow outline will be displayed at the local maximum eclipse if the click is inside the path, i. When hovering the cursor over the various contact events the position of the shadow outline will be recomputed at the current contact time. Eclipse type Duration The type and duration of the eclipse as seen at your location taking into account that the Sun may not be above the horizon until the eclipse is in progress, etc. The corrected duration taking into account the lunar limb profile is displayed only inside the path of totality. Displays if the eclipse is underway at sunrise or sunset,UmbralAntumbral depth The percentage of the way from the edge of the eclipse to the centre line that this location is at,Path Width The width of the total or annular path in kilometers,Obscuration The percentage of the Suns disk surface covered at maximum eclipse this box will display if the Sun is below the horizon at maximum eclipse,Magnitude at maximum The fraction of the Suns diameter covered by the Moon at the local maximum eclipse,MoonSun size ratio The ratio of the apparent size of the Moon to that of the Sun at the local maximum eclipse,UmbralAntumbral velocity The speed of the umbraantumbra,Eclipse diagram The eclipse diagram displays the relatives positions of the Sun, Moon and ground in horizontal coordinates the refraction and terrain declivity are not taken into account. The solar north is indicated by the red tick mark and the diagram is updated when hovering the cursor over the various contact events. Eclipse Event or sunrisesunset,The Universal Time UT Date and Time of the event. When the event occurs while the Sun is below the horizon, an asterisk will appear after the hour. The given time is provided without any lunar limb correction, to know the time with the limb correction just add the value found in the LC column. Be aware that the computations are executed using the standard IAU 1.

To have the value with the atmospheric refraction, hover the cursor over the value for a few seconds to get a tooltip,Azi Azimuth of the sun, in degrees 0 due north, 9. P Angle, in degrees, between the north point on the Suns disk and the contact point with the Moon. When the current event is sunrise or sunset, the obscuration of that event is displayed over the two columns when the eclipse is in progress the time is then rounded to the nearest minute and the atmopsheric refraction not taken into account,V The oclock position on the Suns face of the contact point with the Moon eg V1. Suns disk,LC The calculator is able to determine a correction factor to the time of the start and end of the eclipse due to the fact that the Moons limb is not smooth. When it is, then the correction in seconds is given. A click on the LC column header will display the lunar limb profile and Bailys beads in a new window. Cheese Quesadilla, Green Beans, Potato ChipsPretzels, Pineapple Tidbits, Fresh Fruit, Juice Cups, Milk 1 White, Milk FF Chocolate, Alt Salad Bar, Alt Hot Dog. A Google employee familiar with the feature spoke to Lifehacker to clarify how corrections to the OneBox section affect search results. Feedback is ordered by.

Grand Theft Auto V is an actionadventure video game developed by Rockstar North and published by Rockstar Games. It was released on 17 September 2013 for PlayStation. The Sims Hogwarts Wizarding World. Solar Eclipse Google Map help by Xavier Jubier. Tools. All the tools can be activated by clicking on their respective icon. Plus one more click to deactivate them. The timezone tool will give you the time offset needed to compute local time at the observers location. The road traffic tool will indicate you the current state of the road traffic. The road traffic can be activated by default when loading the map by just appending Traffic1 to the URL. The elevation profile in the maximum eclipse line of sight is there to let you make sure the eclipse will be visible over the horizon. To compute it, first click on the elevation tool to activate and then click at the observers location. The min value is the minimum height between the bottom of the solar disk and the terrain. If negative, then part of the eclipse will not be visible the apparent diameter of the Sun is roughly half a degree. The day and night areas can be activated by default when loading the map by just appending ND1 to the URL. The day and night tool will let you display areas where the Sun is set at the given time from the observers location. The areas if civil twilight, nautical twilight, astronomical twilight and night are all shaded appropriately. When hovering the cursor over the various contact events the display will be updated to show the situation at the contact event time. The elevation profile can be activated by default when loading the map by just appending EP1 to the URL. When activated the geolocation tracking tool will constantly center the map on the observers location while displaying the local eclipse circumstances. When zooming far enough you can visualize around your location the 9. To work this feature needs you to allow geolocation please refer to your browsers privacy settings your operating system may also have some geolocation privacy settings. Please take note that no data is transmitted or stored on the server generating the map. Various techniques GPS cellphones, triangulation GSM3. G4. GLTE cellphones, Wi Fi triangulation cellphones and MAC address databases, IP address correspondence with databases are put to use for more or less accurate geolocation. Over time they can be combined to refine the result. Some methods such as GPS are slower than others and more energy intensive especially on cellphones. That is why the first step is often to get a rough approximation often by GSM triangulation and then start up the GPS module after a few seconds this is visualized on i. OS by the gradual decrease of the extent of blue circle. The geolocation can be activated by default when loading the map by just appending GL1 to the URL. Limitations. Those computations do not account for atmospheric refraction, which makes a difference if the eclipse occurs close to sunrise or sunset a good example of this was the midnight Sun eclipse in Antarctica on November 2. However, by hovering the cursor over the altitude value a tooltip will show the correction with refraction,Corrections for the irregular lunar limb are only available when you are online, i. Internet. This can produce a few seconds time difference on the start and end of totality or annularity,It is not possible to predict the exact value of T in advance, although the extrapolated value should be good to better than 0. Acknowledgment. Thanks to Sergey and Larry for making regular and timely imagery updates to locations where eclipse chasers will be going.
