Following reports of renewed optical activity in the black hole X-ray transient MAXI J1820+070 (ATel #14492), we observed the source with NICER and Swift on March 29. NICER started observing MAXI J1820+070 around 19:44 UTC for ~670 s. The source was detected significantly above the background between ~0.4 and ~2 keV, with a 0.4-2 keV source count rate of 0.49+/-0.03 cts/s.
