// The GOES Mesoscale images come in two domains.
// Separate the two groups using ee.Filter.eq.
var goes17_mcmipm = ee.ImageCollection('NOAA/GOES/17/MCMIPM');
var goes17_mcmipm_2019 =
    goes17_mcmipm.filterDate(ee.Date('2019-11-01'), ee.Date('2019-11-05'));

var d1 = goes17_mcmipm_2019.filter(ee.Filter.eq('domain', 1));
var d2 = goes17_mcmipm_2019.filter(ee.Filter.eq('domain', 2));
print(goes17_mcmipm_2019.size()); 
print(d1.size());
print(d2.size());
