We report the discovery of two extreme scattering events (ESE; 1, 2) in progress:

PMN J1740-0811 (RA=17:40:01.6 dec=-08:11:14.8 J2000) appears to be a long duration ESE which started about MJD 57300. It appears to be currently demagnified.

87GB 192724.2+090329 (RA=19:29:47.9 dec=+09:10:03.6 J2000) is a rapid ESE that probably began around MJD 57360. It appears to be currently during its second magnification.

Radio light curves and spectra are available here [3]

We are currently monitoring both ESEs with the ATCA and VLBA. We encourage multiwavelength monitoring.
