Finding Local Maxima Peaks in Solar Data
Detecting intensity peaks in solar images can be useful as
a simple flare identification mechanism. This example illustrates detection
of those areas where there is a spike in solar intensity.

In this feature I worked on  implementing the *skimage.feature.peak_local_max*
function to find the local peaks in the solar data collected from AIA plot.

Using the *map functionality* in SunPy we first plot the AIA data.

Now using the peak function from  skimage we plot the AIA data distribution showing the local peaks.

Once we get the local peaks position, we plot those coordinates in the actual AIA map plot.
