In this talk, I will discuss the current state of the MASCARA and bRing networks, and go into detail on how our observations can be combined with TESS to search for long period transiting exoplanets. These networks have discovered four exciting transiting exoplanets which are ideal for follow up atmospheric characterization surveys. The near continuous observations of these networks provides a unique synergy with TESS, where our long-term monitoring of all stars brighter than 8.4 magnitudes in the sky will provide information needed to find long period transiting systems when combined with the shorter term TESS data. The MASCARA and bRing networks are composed of a set of observatories in the northern and southern hemispheres with the aim of finding Hot Jupiters around bright stars using photometry. They are composed of four stations, two main MASCARA stations located in La Palma, the Canary Islands and La Silla, Chile, and two smaller bRing stations in Sutherland, South Africa and Siding Springs, Australia. Each MASCARA station is equipped with five interline CCD cameras, and observes the local sky down to an airmass of around 2. The smaller bRing stations are equipped with only two interline CCD cameras, and observe the declination range of -30 to -90 degrees down to an airmass of around 10. The bRing stations are combined with the southern MASCARA station, and allows for at least one station observing at any given time for much of the year in the bRing declination range, provided weather permits. With five minute exposures, we obtain photometric observations of tens of thousands of bright stars over years with a window function which is unprecedented for ground-based observatories. All MASCARA data will soon be freely available through the ESO database.
