Abstract
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.
