Note: I try to keep this magnetogram On-line 24H/Day. Around 7:30UTC and 17:00UTC passing cars and garagedoors opening/closing are causing 25nT disturbances in the magnetogram. I try to correct the data as often as possible to keep the magnetogram accurate.
A big change in temperature is also affecting the magnetogram. Temp down > mgram slowly goes up | Temp up > mgram slowly goes down. I'm working to solve this problem.
