Add to ORKGFollowing the report of a new outburst of the accreting millisecond pulsar SAX J1808.4-3658 by Markwardt and Swank (ATel #1728), the source was observed using the CTIO/SMARTS 1.3m telescope on MJD 54732.0998, in I- and H- bands. We clearly detected the source at magnitudes significantly higher than its quiescent level, confirming that the source is indeed in outburst
