Observations of the Solar Faculae at San Fernando Observatory and Solar Dynamics Observatory
Abstract
In this paper we compare the full disk images of the Sun obtained in 393.4 nm Ca II K line from Cartesian Full Disk Telescopes (CFDT) of San Fernando Observatory (SFO) and 1600Å and 1700Å images from Solar Dynamic Telescope (SDO). The facular excess and facular area are determined for these two types of images using the data reduction procedure developed at SFO. We find strong correlation between the derived quantities from SFO and SDO images. Also, the facular excess and facular area show a very good correlation with the sunspot numbers. The sunspot numbers derived from the SDO images from our model agrees well with tabulated values.
