Welcome to Helios ( / hiːli.os /; Greek:Ἥλιος"Sun", Latinized as Helius) scientific project!Helios is a scientific application designed to uniteSolarAmateur Observers around the world, by gathering informationoftheir observations to a common place for further analysis. Thedatafrom the observations is send to a server and then it isprocessedto create graphics using MRTG (Multi Router TrafficGrapher).How does it work?1. When an Observer makes a new daily observation and logsdownhis results in the Helios application, he has the ability tosendthe data to the WWSOS (World Wide Solar ObservationServer)server.2. If the Observer uses an Android mobile phone, the phone numberisused as a unique identification number by the application andallowsone Observer to communicate with another Observer or otherObserversvia SMS messages.3. If the Observer uses an Android tablet PC withoutGSMcapabilities the application uses the tablet's model as auniqueidentification number but lucks the capability to communicatewithothers.4. When new data reaches the server, a poller application plotstheuser's data and presents a graph within 5 minutes. The unique idisused to identify the graph that corresponds to theObserver.5. The server assumes that a normal observation time will lastforat least (1) one hour. If no further data, is received withintheallowed time, the graph's data value is reset to (0) zero.

Calculate the Gegenschein CoordinatesAlso known as the Counterglow. The Gegenschein is veryfaintlight seen on the ecliptic, 180o from the Sun. It is part ofthezodiacal light and it is a reflection of light by dust particlesinthe ecliptic plane of the solar system. It is about 15o to20oacross, and it's fainter by a factor of 15 relative to thezodiacallight. It is best seen when it is far from the Milky Way(Galacticplane) in September and October.
